How are monsoons caused?
The primary cause of monsoons is the difference between annual temperature trends over land and sea. This low pressure regions sees continuous rise of moist wind from the sea surface to the upper layers of the atmosphere, where the cooling means the air can no longer hold so much moisture resulting in precipitation.
How do monsoons work?
A monsoon is a seasonal change in the direction of the prevailing, or strongest, winds of a region. Monsoons cause wet and dry seasons throughout much of the tropics. Monsoons are most often associated with the Indian Ocean. Monsoons always blow from cold to warm regions.
Why do monsoons happen in India?
What Causes the Monsoon in India. The monsoon is caused by differing temperature trends over the land and ocean. During the monsoon, the wind direction reverses. Moisture-laden winds from the Indian Ocean come to fill up the void, but because they can’t pass through the Himalayas region, they’re forced to rise.
What are the disadvantages of monsoons?
1) Rain water creates flood situation everywhere and hence that kills thousands of people and animals. Also the flood damages the crops and other plants. 2) Excess rainfall forces migration of the people living in the area closer to the river catchment. 3) Also rain water causes excessive load on our drainage system.
What is monsoon and its types?
A monsoon is a seasonal wind system that shifts its direction from summer to winter as the temperature differential changes between land and sea.
What is monsoon mean?
1 : a periodic wind especially in the Indian Ocean and southern Asia. 2 : the season of the southwest monsoon in India and adjacent areas that is characterized by very heavy rainfall. 3 : rainfall that is associated with the monsoon.
Where are monsoons most common?
The most prominent monsoons occur in South Asia, Africa, Australia, and the Pacific coast of Central America. Monsoonal tendencies also are apparent along the Gulf Coast of the United States and in central Europe; however, true monsoons do not occur in those regions.
What is an example of a monsoon?
An example of a monsoon is a storm that causes heavy flooding and extreme wind damage. A wind from the southwest or south that brings heavy rainfall to southern Asia in the summer. The disparity causes strong winds to blow between the ocean and the land, bringing heavy seasonal rainfall.

Why is monsoon known as uncertainty?
1 Answer. (i) The movement of low-pressure trough controls the spatial distribution of rainfall. (ii) The alteration of wet and dry spells varies in intensity, frequency and duration. (iii) It sometime causes heavy floods in one part, it may be responsible for drought in other.
What is the monsoon known for?
Monsoon is known for its uncertainties. The alteration of dry and wet spells of rains vary in intensity frequency and duration, while it causes heavy floods in one part, it may be responsible for droughts in the other.
How is monsoon known for its uncertainty Class 9?
Answer: The alternation of dry and wet spells varies in intensity, frequency and duration. It may cause heavy floods in one part and drought in the other part. It is often irregular in its arrival and retreat.
What are the vagaries of monsoon explain?
In India, the subnormal and abnormal activities of the Monsoon affecting the seasonal pattern of rainfall are known as the vagaries of monsoon. It is caused by the early arrival or late withdrawal of rainfall which ruin the crops leading to slowdown of the economy. The Monsoon in India is erratic and irregular.
What are southwest monsoon winds?
This is the southwest monsoon. This causes the winds to blow over the Indian subcontinent toward the Indian Ocean in a northeasterly direction, causing the northeast monsoon. Because the southwest monsoon flows from sea to land, it carries more moisture, and therefore causes more rain, than the northeast monsoon.
What are the features of monsoon Class 9?
Around the time of its arrival, the normal rainfall increases suddenly and continues constantly for several days. This is known as ‘burst’ of the monsoon. (d) The monsoon has a tendency to have ‘breaks’; thus, it has wet and dry spells. In other words, monsoon rains take place only for a few days at a time.
What are the characteristics and effects of monsoon rainfall in India?
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.

What are the characteristics of the tropical monsoon climate?
Tropical monsoon climates have monthly mean temperatures above 18 °C (64 °F) in every month of the year and a dry season. Tropical monsoon climates is the intermediate climate between the wet Af (or tropical rainforest climate) and the drier Aw (or tropical savanna climate). of average monthly precipitation.
