(i) During winter, a high pressure area develops north of the Himalayas.
(ii) Cold dry winds blow from this region to the iow pressure areas over the
oceans to the south.
(iii) In summer, a low pressure area develops over interior Asia as well as
over northwestern India.
(iv) This causes a complete reversal of the direction of winds during
summer.
(v) Air moves from the high pressure area over the southern Indian ocean
in a south-westerly direction, crosses the equator and turns right towards
the low Pressure area over the Indian sub-continent.
(vi) These winds are known as south-west monsoon winds.
(vii) These winds blow over the warm oceans, gather moisture and bling
widespread rainfall over the mainland of India.
(i) Latitude: Due to the round shape of the Earth, the amount of solar energy received varies according to latitude. As a result, air temperature decreases from the equator towards the poles.

(i) Latitude: Due to the round shape of the Earth, the amount of solar energy received varies according to latitude. As a result, air temperature decreases from the equator towards the poles.
(ii) Altitude: As one moves up to the higher altitudes, the atmosphere becomes less dense and temperature decreases. Therefore, hills are the cooler during summers.
(iii) Pressure and winds: Pressure and winds system of an area depend on the latitude and altitude of the place. Thus, it influences the temperature and rainfall pattern.
(iv) Distance from the sea: If the region is close to the sea, it makes the temperature moderate but if it is away from the sea, it experiences extreme weather conditions.
(v) Ocean currents: Ocean currents along with the onshore winds affect the climate of a coastal area. Any coastal area with warm or cold currents flowing past it, will become warm or cold if the winds are onshore.
(vi) Relief: High mountains act as barriers for cold and hot winds. They may also cause precipitation if they lie in the path of rain-bearing winds. The leeward side of mountains remains dry, whereas the windward side is able to receive rain.
(i) There are variations not only in the form and types of precipitation but also in its amount and the seasonal distribution. (ii) Precipitation is mostly in the form of snowfall in the upper parts of the Himalayas but it rains over the rest of the country. (iii) The annual precipitation varies froRead more
(i) There are variations not only in the form and types of precipitation but also in its amount and the seasonal distribution.
(ii) Precipitation is mostly in the form of snowfall in the upper parts of the Himalayas but it rains over the rest of the country.
(iii) The annual precipitation varies from 400 cm in Meghalaya to less than 10 cm in Ladakh and western Rajasthan.
(iv) Most parts of the country receive rainfall from June to September but some parts like the Tamil Nadu coast gets most of its rains during October and November.
(i) In summer the maximum temperature goes up to 50'C in some part of Rajasthan. (ii) Whereas it may be around 20'C in Pehalgam in Jammu and Kashmir. (iii) The night temperature at Drass in Jammu and Kashmir may be as low as minus 45'C. (iv) Thiruvananthapuram, on the other hand may have a temperatuRead more

(vi) On the other hand there is hardly any difference in the day and night temperatures in Andaman and Nicobar islands or in Kerala.
Leh is also called a cold desert. (i) Leh has moderate precipitation almost throughout the year because of its topographical location. (ii) It lies on the landlocked high Ladakh plateau, beyond the Himalayas. (iii) The local precipitation is very less, but it is well distributed in the form of rainsRead more
