Global winds are caused by the combination of pressure belts and the Coriolis effect. Secondary Winds or Periodic Winds These winds change their direction with change in season. This belt is subjected to seasonal and spatial variations due to northward and southward movement of the overhead sun (summer and winter solstices). These views of weather conditions pre­vailing in the tropics are now considered as old con­cepts and have now been refuted on the basis of new information based on numerous observations made in the upper air and near the earth’s surface during and after Second World War. The equatorial or tropical fronts are called intertropical fronts (ITF) or intertropical convergence (ITC). : (1) over the tropic of Cancer, 21 June) and comes back to its normal position on Sept. 23 and then shifts southward at the time of winter solstice (when the sun is vertical over the tropic of Capricorn, 22 December). Winds which blow throughout the year from one latitude to another in response to the latitudinal difference in pressure are known as planetary winds. Planetary winds produce surface ocean currents. Along with rising sea levels, King Tides, and the effects of El Niño, oceanic R… These cyclones move along with the westerlies in easterly direction. This Blog consists of data, information, paragraph,direct writings of geography stuffs collected from various sources. These are of three types: i) Trade winds. The illustration below portrays the global wind belts, three in each hemisphere. These winds blow over the vast area of the continents and oceans. The winds blowing almost in the same direction throughout the year are called prevailing or permanent winds. I accumulated, modified, simplified . According to Ferrel’s law (based on coriolis force generated by the rotation of the earth) trade winds are deflected to the right in the northern hemisphere and to the left in the southern hemisphere. At some places on the lands (e.g. Winds blowing from polar high to sub polar low pressure belt, Are very cold in nature as originate in polar areas & do not cause much rainfall, These winds give birth to cyclones when they come in contact with westerlies, Brings frequent change in weather conditions & causes heavy rainfall. These winds being controlled by the pressure belts blow towards the same direction throughout the whole year. Lv 5. Planetary wind definition is - one of the major winds. Planetary winds are also known as permanent or prevailing winds They blow over the vast area of continents and oceans. This is why hot and dry tropical deserts are found in the western parts of the continents within the latitudinal zones of 20°-30° in both the hemispheres (e.g. Before uploading and sharing your knowledge on this site, please read the following pages: 1. Image Guidelines 4. Planetary Winds Planetary winds comprise winds distributed throughout the lower atmosphere. On an averages, the location of high and low pressure belts is considered to be stationary on the globe (though they are seldom stationary). They are also associated with boisterous-gales. Examples of planetary-scale phenomena include: Semi-permanent pressure centers (the Aleutian Low, Bermuda High, Polar Vortex) The westerlies and trade winds; Synoptic or Large Scale Weather . to S.E in the southern hemisphere. Flohn has further maintained that south-western monsoons are, infact, equatorial west­erlies because these winds are extended upto 30-35°N latitudes over Indian subcontinent due to northward shifting of NITC at the time of summer solstice (fig. According to Flohn the doldrums ex­tend upto 200 longitudes in discontinuous manner. This belt of calm is very popularly known as horse latitudes because of the fact that in ancient times the merchants had to throw away some of the horses being carried in the ships in-order to lessen the weight so that the ships could be sailed through the calm conditions of these latitudes. J. This is why the anticyclonic conditions cause atmos­pheric stability, dry condition and very weak air circu­lation. The weather conditions in the tropics are not calm and uniform but they are frequently interrupted by atmos­pheric disturbances (cyclones, hurricanes, typhoons, sea waves etc.). Generally, winds are named based on the direction in which they flow, hence global or planetary winds blow from high-pressure belts to low-pressure belts. The wind belts are basically controlled by the latitudinal pressure belts and by the forces produced by rotation of the earth. Example sentences with "planetary wind", translation memory The plasma flowing down the tail along the open field lines is called the planetary wind. The Earth's atmospheric circulation varies from year to year, but the large-scale structure of its circulation remains fairly constant. There is more or less regular inflow of winds from subtropical high pressure belts to equatorial low pressure belt. 1. Slow-moving oceanic Rossby waves are are fundamentally different from ocean surface waves. Unlike waves that break along the shore, Rossby waves are huge, undulating movements of the ocean that stretch horizontally across the planet for hundreds of kilometers in a westward direction. The deflection of earth's planetary winds is an example of 1 See answer kishorsoni1709 is waiting for your help. The SeaWinds scatterometer is a specialized microwave instrument that measures near-surface wind speed and direction all the time, even when it is cloudy. Other articles where Planetary wind system is discussed: Pacific Ocean: Climate: …Pacific conform closely to the planetary system—the patterns of air pressure and the consequent wind patterns that develop in the atmosphere of the Earth as a result of its rotation (Coriolis force) and the inclination of its axis (ecliptic) toward the Sun.

The direction of such winds remains more or less the same throughout the year though their areas change seasonally. Prohibited Content 3. Philosoraptor. These westerly winds have been called by Flohn as equatorial westerlies (fig. Sahara and Kalahari in Africa, Chile-Peru desert or Acatama in South America, Arabian and Thar deserts in Asia, deserts of S. W. USA, and Australian deserts). The main planetary winds are: (i) the North-east and the South-east Tradewinds (ii) the Temperate Westerlies (iii) thePolar Easterlies, which blow from the polar … This video explains Planetary Winds namely Trade Winds, Westerlies and Polar Easterlies and cells for wind movement namely, Hadley Cell, Ferrel Cell and Polar Cell. Report a Violation 10. Since these winds are distributed all over the globe and these are related to thermally and dynamically induced pressure belts and rotation of the earth and hence they are called planetary winds. Wind is the flow of gases.On Earth, wind is mostly the movement of air.In outer space, solar wind is the movement of gases or particles from the sun through space. (3) Western Coastal Margin of Central America. Westerlies are the examples of planetary winds. Convergent wind zones are where planetary wind belts meet. Terms of Service 7. 9 years ago. 35.7). in the northern hemisphere and N.W. Spanning somewhat smaller, yet large distances of a few hundred to several thousand kilometers, are synoptic scale weather systems. (1) the planetary winds, (2) the monsoon winds, (3) cyclones and anticyclones (4) local winds. 35.8) viz. The eastern parts (spreading over the western parts of the continents) are marked by descent of air currents, inversion of temperature and consequent atmospheric stability and dry conditions. 35.10). THE ANTARCTIC PLATEAU: TYPE EXAMPLE OF A PLANETARY WIND DOMINATED LANDSCAPE. Content Filtration 6. Crowe has identified 3 zones of doldrums e.g. See the equator zone, 00 Divergent wind zones are where wind belts are moving away from each other. The velocity of the westerlies becomes so great that they are called roaring forties between the latitudes of 40°-50° S, furious fifties at 50°S latitude and shrieckng sixties at 60° S latitude. A few meteorologists and climatologists be­lieve in the existence of cyclonic fronts in the equato­rial regions while some refute this concept on the ground that fronts are formed only when two air masses of contrasting temperatures converge but such conditions are not found in the equatorial region. Similar to the solar wind, the planetary wind is composed of light gases that escape planetary atmospheres. Trade wind definition, any of the nearly constant easterly winds that dominate most of the tropics and subtropics throughout the world, blowing mainly from the northeast in the Northern Hemisphere, and from the southeast in the Southern Hemisphere. Such phenomena are typically a few thousand kilometres in size and have lifetimes ranging from several days to several weeks. The general distribution of winds throughout the lower atmosphere is known as planetary winds. In a continuous 1,800 … Although designed for measurements over the ocean, SeaWinds can also collect data over land and ice. See more. Also known as brave winds or roaring forties, furious fifties & shrieking sixties according to the varying degree of storminess in the latitudes in which they blow. Their velocity increases southward and they become stormy. Examples of planetary-scale phenomena include the semipermanent pressure centres discussed above and certain globe-encircling upper-air waves (see below Upper-air waves). Winds blowing from subtropical high pressure area to equatorial low pressure area (Extremely steady winds), Since they travel from high latitude to low latitude area, they become gradually hot & dry and hence have a great capacity to hold moisture, They cause considerable rainfall on eastern margins of the continents as they get moisture after blowing over oceans, These winds converge near equator & form ITCZ, Here these winds rises & causes heavy rainfall, Winds blowing from subtropical high pressure belts towards subtropical low pressure belts, Blow from S – W to N – E under Coriolis effect in N – Hemisphere & from N – W to S – E in S – Hemisphere, Blow from lower latitudes to higher latitudes, Cause considerable rainfall particularly on western margins of the continents, More consistent in direction & blow with stronger force in S – Hemisphere due to lesser obstructions from continents. In this article we will discuss about the classification of planetary winds. Anticyclones are produced due to subsidence of air currents in the horse latitudes. For­merly, it was believed that trade winds blow from the subtropical high pressure belts to the equatorial low pressure belt. Explain how local winds are different from planetary winds. Planetary winds pdf Hot air rises.draw diagram showing pressure belts and planetary winds. The Icelandic and Aleutian low pressure cells persist throughout the year. Indo-Pacific Doldrum extending from the eastern coast of Africa to 180° longitude for a distance of 16,000 km and cover­ing an area of 25,800,000 km2, thus, covers about one third of the total length of the equator, (2) Equatorial Western Coastal Region of Africa, and. b. seasonal changes. Because of the dominance of anticyclonic conditions there is strong atmospheric stability, strong inversion of tem­perature and clear sky. Contrary to common consensus, the team found that stellar winds are not spherical but have a shape similar to that o to N.E. Trade winds blow in a belt lying between 5°N-30°N in the northern hemisphere and 5°S-30°S in the southern hemisphere. Global Wind Explained. Planetary winds: The primary winds are known as Planetary winds. The westerlies become more vigorous in the southern hemi­sphere because of lack of land and dominance of oceans. d. tilted axis. Each of these wind belts represents a "cell" that circulates air through the atmosphere from the surface to high altitudes and back again. On an average, there is westerly air circulation (form west to east) in the doldrums or say in the intertropical convergence. It’s an amazing contradiction.” And that’s not the only mystery blowing in the planetary wind. The northern and southern boundaries of intertropical convergence are called north intertropical convergence (NITC) and south intertropical convergence (SITC) respectively (fig. Because of the dominance of land in the northern hemisphere the westerlies become more com­plex and complicated and become less effective during summer seasons and more vigorous during winter season. These westerlies bring much precipitation in the western parts of the continents (e.g., north-west European coasts) because they pick up much moisture while passing over the vast stretches of the oceans. On the other hand, winds with seasonal changes in their directions are called seasonal winds (e.g., monsoon winds). They are tropical easterly or trade winds, westerlies and polar easterlies. The winds at the surface may be classified into four main types, viz. The western parts of subtropi­cal anticyclones (covering the eastern parts of the continents and western parts of the oceans) are humid because some sort of atmospheric instability is caused due to weakening of air descent (e.g., in the areas of Caribbean Sea, Mexican Gulf and adjoining areas, eastern China, southern Japan, south-east Brazil and eastern Australia). Thus, this zone (30°- 35°) is characterized by weak and variable winds and calm. Atmospheric Circulation, Climatology, Geography, Planetary Winds, Winds. Planetary winds are also known as permanent or prevailing winds, Blow from high to low pressure, over the earth surface & oceans throughout the year & in a particular direction. There is much variation in the weather conditions in their poleward parts where there is con­vergence of cold and denser polar winds and warms and lighter westerlies. The Earth's planetary winds are deflected as a result of the Earth's? The north-east and south-east trades converge along the equator and there are upper air anti­trades blowing in the opposite directions of the surface trade winds. shwetlana3026 shwetlana3026 The deflection of earth's planetary winds is an example of corioles effect which is created by revolution of the earth How to use planetary wind in a sentence. 3Radebaugh1, L. Kerber2, R. Harvey3, J. Karner4, ... winds are typical for the Antarctic plateau, so as the storm moved out, the winds resumed and blew the snows, often with the texture of small, sand-like ice The weather conditions throughout the tropical zone remain more or less uniform. These anticyclones are known as ‘subtropical highs’ or subtropical anticy­clones, the eastern and western parts of which are characterized by contrasting weather conditions. It has been discovered that trade winds blow with regularity only over some parts of the tropical oceans (mainly over the eastern parts). These winds are called trade winds because of the fact that they helped the sea merchants in sailing their ships as their (of trade winds) direction remains more or less constant and regular. On the other hand, winds with seasonal changes in their directions are called seasonal winds (e.g., monsoon winds). The discovery is based on a set of observations of stellar winds around aging … There is seasonal shifting in the NITC and SITC with the northward (summer solstice) and south­ward migration (winter solstice) of the sun. Astronomers present an explanation for the mesmerizing shapes of planetary nebulae. c. rotation on its axis. Thus, the descent of winds from above causes high pressure on the surface which in turn causes anticyclonic conditions. The discovery is based on an extraordinary set of observations of stellar winds around aging stars. Monsoons are the best example of large-scale modification of the planetary wind system. Add your answer and earn points. Global winds or Planetary winds are large body air masses created mainly as a result of the earths rotation, the shape of the earth and the suns heating power. The winds blowing almost in the same direction throughout the year are called prevailing or permanent winds. Account Disable 11. Planetary winds pdf DOWNLOAD! There is a belt of calm or doldrum characterized by feeble air circulation. The wind, moving in one general direction, pushes the ocean water to produce these currents (see Ocean Surface Currents chart). Thus, such winds are called permanent winds. This belt is called the belt of calm or doldrum because of light and variable winds. NASA's QuikSCAT satellite carries the SeaWinds instrument, a scatterometer.A scatterometer is a microwave instrument that measures the microwaves reflected or scattered back to the instrument from the sea surface. Generally, the areas extending between 30°N and 30°S latitudes are included in tropical zone. In fact, a cyclonic front, called as polar front, is formed due to two contrasting air masses as referred to above and thus temperate cy­clones are originated. According to Flohn the equatorial westerlies cover the areas extending from the western parts of Africa across the Indian Ocean to the western Pacific Ocean. PLANETARY WINDS The general, permanent circula­tion of surface winds throughout the world is.denoted by the term 'planetary winds'. Copyright 9. S.E. The air after being heated near the equator ascends and after blowing in opposite direction to the surface trade winds descends in the latitudinal zone of 30°-35°. The poleward parts of the trade winds or eastern sides of the subtropical anticyclones are dry because of strong subsidence of air currents from above. c. rotation. On Earth, winds get faster as you get higher in the atmosphere. Important Geophysical phenomena such as earthquakes, Tsunami, Volcanic activity, cyclone etc., 1. Planetary winds: The general distribution of winds throughout the lower atmosphere is known as planetary winds. Topic: Salient features of world’s physical geography. a. revolution around the Sun. 1 Answer. The zone of polar winds shrinks due to northward shifting of pressure belts at the time of northern summer (summer solstice) in the northern hemisphere but it is extended up to 60°N latitude during northern winter (winter solstice). This type of gas loss from a planet into space is known as planetary wind. A low pressure belt, produced due to dynamic factor, lies within the latitudinal belt of 60°-65° in both the hemispheres. In fact, the belt of doldrum shifts northward during summer solstice (when the sun is vertical (fig. The planetary wind is of three types such as : the trade wind, the westerlies and the polar wind. These are also called as invariable or planetary winds because they involve larger areas of the globe. It was believed that doldrum is a regular feature all along the equator and is character­ized by strong convective instability leading to the formation of cumulonimbus clouds and copious rain­fall daily but the recent observations have now shown that the belt of doldrum is not continuous but is con­fined to certain localities only. It must be noted that not all the western coast of the temperate zone (30* – 60*) receive Westerlies throughout the year due to shifting of wind belts coz of earth’s inclination. 35.10) which cover 200° longitudes. The permanent winds blowing from the subtropical high pressure belts (30°-35°) to the subpolar low pressure belts (60°-65°) in both the hemispheres are called westerlies (fig. Feedback from star-formation, in the form of supernova explosions of massive stars, stellar winds or ultraviolet radiation from massive stars, or outflows from low-mass stars may disrupt the cloud, destroying the nebula after several million years. Information, data, figures are collected from various Sources. Giving examples, highlight the role of local winds in influencing climate, agriculture and livelihood in various regions. The strongest winds seen on a planet in our solar system are on Neptune and Saturn.. Short bursts of fast winds are called gusts.Strong winds that go on for about one minute are called squalls. 35.7). These fronts represent the meeting ground of north-east and south-east trade winds. Atmospheric circulation is the large-scale movement of air and together with ocean circulation is the means by which thermal energy is redistributed on the surface of the Earth.. These are called polar winds which are north-easterly in the southern hemisphere and south-easterly in the south­ern hemisphere. On the other hand, the equator-ward parts of the trade winds are humid be­cause they are characterized by atmospheric instability and much precipitation as the trade winds while blow­ing over the oceans pick up moisture. The winds regularly blow throughout the year confined within latitudinal belts, mainly in north-east and south-east directions or from high-pressure polar-regions to low-pressure regions. These winds are divided into 3 categories viz. New discoveries have now put question marks against the views of zonal character and regularity of surface trade winds, uniformity of weather conditions in the tropics, and upper air antitrade winds. Astronomers have presented an explanation for the shapes of planetary nebulae. Thus, winds blow from polar high pressure to sub-polar low pressure cells. So, in short, the characteristics of planetary winds are as follows: These winds being controlled by the pressure belts blow towards the same direction throughout the whole year. SAMPLE QUESTION •The seasonal shifts of Earth’s planetary wind and moisture belts are due to changes in the 1) Distance between Earth and the Sun 2) Amount of energy given off by the Sun 3) Latitude that receives the Sun’s vertical rays* 4) Rate of Earth’s rotation … Conse­quently, winds blow from high pressure belts to low pressure belts. These tropical winds have north-easterly direction in the northern hemi­sphere while they are south-easterly in the southern hemisphere. Thus, this belt separates two wind systems viz., trade winds and westerlies. This belt of low pressure is more persistent in summer season but generally disappears in winter season. Simple theme. Thus, the general characteristic features of the westerlies are largely modified due to cyclones and anticyclones associated with them. Waves in the ocean come in many different shapes and sizes. There are much variations in the weather conditions in the different parts of trade winds. So, for example, airplanes experience more wind than cars do. Other examples of periodic winds include land and sea breeze, mountain and valley breeze, cyclones and anticyclones, and air masses. Note that the U.S. lies primarily in the Westerly Wind Belt with prevailing winds from the west. “Yet winds are just screaming around the planet. … In both cases, the disruption of the air flow creates imbalances in temperature distribution both vertically and horizontally. The gen­eral direction of the westerlies is S.W. Disclaimer 8. These winds include trade winds, westerlies and polar winds (fig. Powered by, https://www.affairscloud.com/assets/uploads/2016/04/wind.png, Planetary Winds: Their Types and Definition. Planetary winds: Planetary or permanent winds blow in the same direction throughout the year. Mysterious winds. Relevance. A belt of low pressure, popularly known as equatorial trough of low pressure, extends along the equator within a zone of 5°N and 5°S latitudes. They blow over large areas of the globe (across continents and oceans) in the same direction throughout the whole yea… The wind responds by seeking a return to a "balanced" atmosphere and changes speed and/or direction. Asia and southern USA) the trade winds disappear during summer season due to forma­tion of low pressure cells because of high temperature but the trade winds are more constant and regular over the continents during winter season. 35.9). Plagiarism Prevention 5. It may be stated that the trade winds are more regular and constant over the oceans than over the lands. They are so large and massive that they can change Earth's climate conditions. i tried to assemble geography contents for my academic purposes.Geography students might find it handy and may use as hand note. Favorite Answer. An example of a five planetary-wave pattern. The dynamically induced (due to subsidence of air currents) subtropical high pressure belt extends between 30°-35° (25°-35°) lati­tudes in both the hemispheres. There is very high pressure over the poles because of exceedingly low temperature. Thus, the tropical zone is character­ized by doldrum, equatorial westerlies, and trade winds. Examples of star-forming regions are the Orion Nebula, the Rosette Nebula and the Omega Nebula. It may be pointed out that the zone of trade winds is called Hadely Cell on the basis of the convective model prepared by Hadley for the entire earth. …phenomena is known as the planetary scale. It is also apparent that the subtropical high pressure belt is the source for the origin of trade winds (blowing towards equatorial low pressure belt) and westerlies (blowing towards sub-polar low pressure belt) because winds always blow from high pressure to low pressure.
