2. C LIMATE India has varied climatic conditions. Very hot and very cold regions as well as regions with very h e avy rainfa l l and very scanty rai n fall. A large part of south As i a has tr op i cal m ons o on cl i m ate. The climate has been influenced by its position , size and relief features as well as on air, pressure and wind condition .

11. Upper air circulation Upper air circulation or jet stream are fast flowing, narrow air currents found in the atmosphere. The main jet streams are located near the tropopause , the transition between the troposphere (where temperature decreases with altitude) and the stratosphere (where temperature increases with altitude) .

12. JET STREAM IN SUMMER An easterly jet stream is formed towards the end of June over the Indian Peninsula in the south-west monsoon season. It has be e n found that this j et stream is strong when the monsoon is very active. When this jet stream shifts further , towards north latitude, weak monsoon conditions prevail.

13. TIBET JET STREAM IN WINTER Another sub-tropical westerly jet stream is formed along the latitude of 27 degrees North during winter at an average height of 12 Km. The velocity of this jet stream decreases as it migrates to north. This sub-tropical jet adds to the thunder activity in north and north-west India.

16. Cyclones Cyclones are hurricanes that happen in this area. They can cause a great deal of damage.

17. CLIMATE OF INDIA Features of Indian climate Monsoon winds are the main factors that determine the climate of this region. They also influence a large part of India. Seasons The Climate of India may be divided into four seasons- Winter - From December to February Summer - From March to May South-West monsoons or rainy season - June to September Retreating monsoons - October and November

34. Nawomica Sahay, Cambridge school Bangalore The summer monsoon brings in moisture from the Indian Ocean and produces a tremendous amount of rain. The moisture from winter monsoons are largely blocked by the Himalayas.

35. VARIABILITY OF RAINFALL

36. MORE DIVERSITIES………………….. Churu (Rajasthan) records a 50°C or more on a June day. I t i s 19 ° C in T aw ang ( Ar u n a c h a l Prades h) on the s a me da y . Most parts of India receives rainfall during June to September. Tamilnadu coast remains dry during these months. Tura of Meghalaya receives rainfall in a single day is equal to the total rainfall of Ten years in Jaisalmer of Rajasthan. Very low rainfall in North west Himalayas and western Rajasthan which is equal to 10cm per year. Snow fall over the Himalayas. Only rainfall over rest of India. MONSOON REGIME IS THE UNITY OF INDIA

39. WHAT CAN BE DONE???

40. Mango showers are the pre-monsoon showers in the Indian states of Karnataka and Kerala that help in the ripening of mangoes. Also known as April rains or Summer showers, they are a result of thunderstorms over the Bay of Bengal . These summer rains normally come in the second half of the month of April, though the arrival is difficult to predict. The showers prevent the mangoes from dropping prematurely from trees and are crucial for the mango cultivators of South india .
