The immense temperature contrast between two air masses produce a sudden change in the pressure gradient, thus sudden change in the velocity. In Deutschland kommt der Wind oft aus westlicher Richtung, vom Atlantik her. There are primarily two jet streams in each Hemisphere: Subtropical Jet Stream originated in the Equator but flow between 20 to 30 degrees latitude from west to east; Polar Jet stream; originated between 50 to 60 degrees latitude in both hemispheres and flow around 70 to 80 degrees latitudes. They are relatively narrow belts of swift-moving winds having velocity in the range of 100km/hr to 900km/hr. Details, Madhya Pradesh The weather over northern India becomes hot, dry and squally due to larger incoming solar radiation and hot winds like loo.

Electrical Prep Strategy, GATE Enginners Zone, Practice UPSC Previous Years' Prelims Paper. Equatorial extension of the Jet Stream is more in winter because of the southern shift of the pressure belts. Years Paper, JEE Advanced Answer Key This results in more active southwest monsoon and heavy rainfall is caused. Jet streams are typically active at 6 – 11 kilometer above the surface of the earth and is mostly found in the troposphere. The north east monsoon (winter monsoon) is related to the subtropical westerly Jet Stream which blows between 20 degree and 35 degree latitudes in both hemispheres. Engineers Career Group, Qaisar Hafiz - - Recruitment Notification, TPSC - Class XI JEE Main + Advanced 2014-2019, While jet streams do exist in the southern hemisphere, they are strongest between latitudes of 30°N and 60°N. Length profile of these Jets is in the range of 1600-3200 km and depth is around 1-2 km. Helps in the intensification of S-W Monsoon over Indian Subcontinent. During winters, the thermal contrast increases and the intensity of the high pressure centre at the pole increases. Optional by Majid Husain, Law Optional & Test Series by Aditya Tiwari, Integrated Pre Cum Mains Prelims Syllabus, UPSC GS It is found due to the thermal contrast between sub-polar layers and polar layers, and become westerly due to Coriolis force.
