(iii) Which part of India does experience the highest diurnal range of temperature and why? (iv) Which winds account for rainfall along the Malabar Coast? (v) What are jet streams and how do they affect the climate of India? (vi) Define monsoons. What do you understand by ""break"" in monsoon? (vii) Why is the monsoon considered a unifying bond?
Answers
Answer:
1.the control which affect the climate of india are as follow
sea level, magnitude, distance from equator ,sun light effect
2.it is because india is a sub contient region and covered by ocean add seas from three sides gente when the clouds are generated from these seas and ocean the monsoon sinds comes from south gente india calls very near to them so it has a monsoon type climate
Explanation:
1.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
Relief features
2.The monsoon type of climate is characterised by a distinct seasonal pattern. The weather conditions greatly change from one season to the other. These changes are particularly noticeable in the interior parts of the country. The coastal areas do not experience much variation in temperature though there is variation in rainfall patterns. Four main seasons can be identified in India – the cold-weather season, the hot weather season, the advancing monsoon, and the retreating monsoon with some regional variations.
3.Surface winds account for rainfall along the Malabar coast.
4.Jet streams are a narrow belt of high altitude (above 12,000 m) westerly winds in the troposphere. Their speed varies from about 110 km/h in summer to about 184 km/h in winter. A number of separate jet streams have been identified. The most constant is the mid-latitude and the subtropical jet stream.
Over India, these jet streams blow south of the Himalayas, all through the year except in summer. The western cyclonic disturbances experienced in the north and northwestern parts of the country are brought in by this westerly flow. In summer, the subtropical westerly jet stream moves north of the Himalayas with the apparent movement of the sun. An easterly jet stream, called the tropical easterly jet stream blows over peninsular India, approximately over 14°N during the summer months.
5. The seasonal reversal in wind direction during a yeat is called the monsoon. Monsoon tends to have ‘breaks’ in rainfall; which means that there are wet and dry spells in between The monsoon rains take place only for a few days at a time and then come to the rainless intervals.
6. Despite great moderating influences on the climate of India, there are great variations in the temperature conditions. Nevertheless, the unifying influence of the monsoon on the Indian subcontinent is quite perceptible. The seasonal alteration of the wind systems and the associated weather conditions provide a rhythmic cycle of seasons.
