Characteristics of Monsoon Rainfall in India : i. Monsoon winds are not trades as trade winds are steady and permanent winds. ii. They are not steady winds but are pulsating in nature. iii. They are affected by different atmospheric conditions encountered by it. On its way over the warm tropical seas. ADVERTISEMENTS: iv. The duration of the monsoon varies from 100 to 120 days from early June to mid- September. v. Around the time of its arrival, the normal rainfall increase suddenly and continues regularly for several days. Vii. This is called the ‘burst’ of the monsoon. viii.

Characteristics of monsoon rainfall in India: (i) The duration of the monsoon is between 100 to 120 days from early June to mid-September. (ii) Around the time of its arrival, the normal rainfall increases suddenly and continues for several days. This is known as the ‘burst’ of the monsoon. (iii) The monsoon has characteristic wet and dry spells or ‘breaks’ in rainfall. The monsoon rains take place only for a few days at a time. They are interspersed with rainless intervals. (iv) The moisture is carried by pulsating south westerlies that are affected by different atmospheric conditions, thereby giving monsoon rains an uncertain character. The annual rainfall is highly variable from year to year (v) The rainfall is unevenly distributed across the Indian landscape. Parts of the western coast and north-eastern India receive the maximum rainfall. Regions such as parts of Rajasthan, Gujarat, Leh and the leeward side of the Western Ghats receive very little rainfall. Effects of monsoon rainfall in India: (a) Indian agriculture is largely dependent upon the water from the monsoon rains. Late, low or excessive rains have a negative impact upon crops. (b) Due to the uneven distribution of rainfall across the country, there are some regions that are drought prone and some that are flood afflicted. (c) The monsoon provides India with a distinct climatic pattern. Hence, in spite of the presence of great regional variations, it has a unifying influence upon the country and its people.

Answer Characteristics of the monsoonrainfall in India: the duration of the monsoon varies from approximately 100 to 120 days from early june to mid September.The monsoon arrives at the southern tip of the Indian peninsular region generally by thejune's first week. They are distinguished from the pre-monsoon showers because of their increase in amount of rainfalland regularity. Effects of the monsoon rainfall in india: Agriculture in India largely depends onmonsoons for water. Late, low or excessive rains have negative impact upon the crops.Due to the uneven distribution of rainfall across the country there are few places that are drought prone affected and few are flood affected. The monsoon provides India with a diverse climatic pattern. Hence, in spite of the presence of great regional variations, it has a unflying influence upon the country andpeople of this region.

This affects millions of farmers all over the country.

Answer In Rajasthan, the weather is very hot and there is less rainfall.Some part of the state is covered with desert. The thick walls of the houses insulate the people against the heat in summer and extreme cold in winter due to the desert. Flat roofs are easier to construct and as there is not much rainfall, water will not collect on the rooftops. Questions 2. Why is it that the houses in the Tarai region and in Goa and Mangalore have sloping roofs? Answer The houses in the Tarai region and in Goa and Mangalore have sloping roofs because they get heavy rain during the monsoon season. When there are sloping roofs, the rain water can easily flow off towards the ground or to a receptive unit where water is collected instead of collecting on the rooftop. Question 3. Why houses in Assam are built on stilts? Answer Houses in Assam are built on stilts because the state receives abundant rainfall due to which there are chances of floods, In case of flood the water might get inside the houses, if the houses are built on ground level, so in order to avoid flooding of houses, houses are built on stilts and above the ground level. Question 4. Why most of the world’s deserts are located in the western margins of continents in the subtropics?

The tropical easterly winds become dry by the time they reach the wester...
