2. CLIMATE
 India has varied climatic conditions.
 Very hot and very cold regions as well as regions with
very heavy rainfall and very scanty rainfall. A large part of
south Asia has tropical monsoon climate.
 The climate has been influenced by its position, size
and relief features as well as on air, pressure and wind
condition.

12. 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).

13. 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 been found that this
jet stream is strong when
the monsoon is very active.
•When this jet stream shifts
further , towards north latitude,
weak monsoon conditions
prevail.

14. 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.

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

18. 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-
1)Winter - From December to
February
2) Summer - From March to May
3) South-West monsoons or
rainy season - June to September
4)Retreating monsoons -
October and November

• 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.

36. VARIABILITY OF RAINFALL

37. MORE DIVERSITIES…………………..
Churu (Rajasthan) records a 50°C or more on a June day.
It is 19°C in Tawang (Arunachal Pradesh) on the same day.
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.

40. WHAT CAN BE DONE???

41. • 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.
