Types of winds is one one the most important topics in geography. The Planetary winds. 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. Thus, a south wind is deflected as a south-west wind in the northern hemisphere and as a south-east wind in the southern hemisphere. Thus, they are more localised in their extent and cover limited horizontal and vertical dimensions and confined to the lower levels of the troposphere. The Jet Stream is a geostrophic wind blowing horizontally through the upper layers of the troposphere, generally from west to east, at an altitude of 20,000 - 50,000 feet. Good examples of local winds are sea breezes and land breezes, and mountain and valley breezes. UPSC CSE - GS. Geomorphology for General Studies UPSC Civil Services 1. Since trade winds blow from the subtropical latitudes to the warmer equatorial latitudes, they have great capacity of holding moisture. The optional papers are divided into two papers - Papers I & II carrying 250 marks each. The general distribution of winds in the lower atmosphere is called as Planetary winds. 7.

New developments if any: UPSC has the habit of asking questions regarding latest developments in the field. For example, within the tropics, the trade winds blow from the east and hence, north equatorial and south equatorial currents flow east to west. Such winds bring down the temperature of the land like the Kuroshio (warm) current, which flows along the east For the UPSC … Answer: Western Disturbances are low-pressure systems (temperate cyclones) embedded in the Westerlies, the planetary winds that flow from west to east between 30 o - 60 o latitude. Free classes & tests. Prelim special: Pressure belts and global planetary winds. Planetary Winds These winds are also known as Permanent/ Primary or Prevailing Winds.

The two most well- understood and significant winds for climate and … On the other hand, winds with seasonal changes in their directions are called seasonal winds (e.g., monsoon winds). ... Planetary Winds… Planetary winds: These winds blow in the same direction throughout the year. This results in variations in the atmospheric pressure. Trade winds: These winds are mainly caused due to the Coriolis effect and Ferrel’s law. C) Monsoon winds … But due to Coriolis force their direction is deflected. Good Morning Friends, We are Posting Today’s Prelims Marathon . The Planetary wind system of the world accompanies the presence of the High and Low-Pressure Belts. Winds blowing over a warm current become warm and at the same time, pick up moisture. Wind System:-Download PDF Here. UPSC: The UPSC IAS Mains Optional papers carry a total weightage of 500 marks. Body – Explain the impact that the shift in pressure belts has on Mediterranean type of climate, regions lying between 60°-70° latitudes are characterized by two types of winds in a year because of shifting of pressure and wind belts, Monsoon climate is the result of the shifting of pressure and wind belts. Since trade winds blow from the subtropical latitudes to the warmer equatorial latitudes, they have great capacity of holding moisture. Topicwise MCQs for Economy for UPSC. Radhamohan Jena. Planetary winds blow in the same direction throughout the year, while the other types of winds get modified due to certain reasons. Important Geophysical phenomena such as earthquakes, Tsunami, Volcanic activity, cyclone etc., 1. The effect of the earth’s rotation (Coriolis Force) tends to deflect the direction of these winds. Air expands when heated and gets compressed when cooled. This stage is officially known as the Civil Services (Preliminary) exam but in common parlance, aspirants refer to it as UPSC Prelims or IAS Prelims. ; Jet Streams develop where air masses of differing temperatures meet. Planets A celestial body moving in an elliptical orbit around a star is known as a planet. During winter due to southward shifting of pressure and wind belt the planetary system of northeast trade winds is established over the region. The pattern of the movement of the planetary winds is called the general circulation of the atmosphere. Winds are grouped under planetary, periodic and local winds. I pinged you on the Whatsapp number some 30Hrs back.. A) Trade winds done clear. Explain how local winds are different from planetary winds. Winds like Loo, Mistral, Foehn, Bora. The rain-fed and rain-shadow areas are the characteristics of the (A) Cyclonic rainfall (B) Convectional rainfall In the northern hemisphere, they blow towards the equatorial low and called North East Trade Winds. When isobars are straight and when there is no friction, the pressure gradient force is balanced by the Coriolis force and the resultant wind blows parallel to the isobar.

Based on the above parameters, wind can be classified into different types: Planetary winds: These winds are also known as prevailing winds and are caused due to the difference in air pressure from one latitude to another latitude. Winds tend to blow from high pressure belts to low pressure but due to Earth’s rotation are deflected to right in north hemisphere and left in south hemisphere - “Ferrel’s law”. These winds are in the form of large air masses which are being formed due to the earth’s rotation along with the shape of the earth and the sun’s heating power.
