Indian Climate Flashcards
(47 cards)
There are six major controls of the climate of
any place. They are:
Latitude, altitude,
pressure and wind system, distance from
the sea (continentality), ocean currents and
relief features
The Tropic of Cancer passes through the middle
of the country from t
The Rann of Kuchchh in the west to Mizoram in the eas
Coriolis force by
Ferells law
Subtropical westerly jet streams are located approximately
over
27°-30° north latitude
Over India, these jet streams blow
south of the Himalayas, all through the year except in
summer
An easterly jet stream, called the sub-tropical easterly jet stream blows over
peninsular India, approximately over 14°N during the summer months.
These are a narrow belt of high
altitude (above 12,000 m) westerly winds in the
troposphere.
jet streams
are weather
phenomena of the winter months brought in by the
westerly flow from the Mediterranean regio
The western cyclonic disturbances
Tropical cyclones occur during the monsoon as well as in October - November, and are part of the
easterly flow
is a broad trough of low pressure in equatorial
latitudes.
The Inter Tropical Convergence Zone (ITCZ,)
The difference in pressure
over is computed to predict the
intensity of the monsoons
Tahiti (Pacific Ocean, 18°S/149°W) and
Darwin in northern Australia (Indian Ocean,
12°30’S/131°E)
it would mean below
average and late monsoons. A feature connected
with the SO is the El Nino
If pressure is negative
‘El Nino’ is a Spanish word
meaning ‘
the child’, and refers to the baby Christ,
as this current starts flowing during Christmas
Normally when the tropical eastern south Pacific
Ocean experiences high pressure,
the tropical eastern Indian Ocean experiences low pressure.
The Arabian Sea and the Bay
of Bengal branches of the monsoon merge over
the northwestern part of the Ganga plains
Delhi generally receives the monsoon showers
from
the Bay of Bengal branch by the end of
June
characteristic feature of the cold weather
season over the northern plains is the inflow of
cyclonic disturbances from the west and the
northwest
though the total amount of
winter rainfall locally known as ‘
mahawat
In West Bengal, Localised thunder storms are known as the
‘Kaal Baisakhi’.
Mawsynram in the southern ranges of the
Khasi Hills
breaks in monsoon are related to the
movement of the monsoon trough
By the beginning of October, the monsoon
withdraws f
rom the Northern Plains
The bulk of the rainfall of the Coromandel Coast is
derived from
depressions and cyclones.
Mawsynram, the wettest place on the earth is also reputed for
its
stalagmite and stalactite caves
