Where do the monsoon rains come from?
The summer monsoon is associated with heavy rainfall. It usually happens between April and September. As winter ends, warm, moist air from the southwest Indian Ocean blows toward countries like India, Sri Lanka, Bangladesh, and Myanmar. The summer monsoon brings a humid climate and torrential rainfall to these areas.
What two factors cause the monsoon?
The primary cause of monsoons is the difference between annual temperature trends over land and sea. The apparent position of the Sun with reference to the Earth oscillates from the Tropic of Cancer to the Tropic of Capricorn. Thus the low pressure region created by solar heating also changes latitude.
Why do summer monsoon rains arrive on the west coast of India?
According to this theory, the onset of the southwest monsoon is driven by the shift of the subtropical westerly jet north from over the plains of India toward the Tibetan Plateau. This shift is due to the intense heating of the plateau during the summer months.
Where are the two major monsoon systems located?
Monsoon systems are associated with colocated pairs of continents such as Asia and Australia, or continents straddling the Equator such as north-west and south-west Africa, and North and South America defining, respectively, the Asian–Australian monsoon system, the West African monsoon, and the American monsoon.
What are the advantages of monsoons?
Advantages: Monsoon rains give a good beneficiary for the farmers and agriculture. The rainfall helps in storing water for irrigation, electric power and drinking. A proper usage of monsoon leads to the prosperity for agriculture and everyone.
What are the negative effects of monsoons?
Summer monsoons can bring heavy rains that destroy homes, damage infrastructure, wash away crops and destroy Water, Sanitation and Hygiene (WASH) infrastructure. During winter monsoons, dry weather can lead to drought and crop failures from lack of moisture.
What are the types of monsoons?
MANILA, Philippines—Monsoons are seasonal winds that bring heavy rains. According to the Philippine Atmospheric Geophysical and Astronomical Services Administration, the country experiences two kinds of monsoons—the northeast monsoon and the southwest monsoon.
What are 3 effects of a dry monsoon?
Yet the main health hazards during summer monsoon season are diseases like cholera, dengue, chikungunya, and malaria, as well as stomach and eye infections.
What are the factors affecting Indian monsoon?
Factors influencing the onset of SW monsoons:
- Intense low-pressure formation over the Tibetan Plateau.
- The permanent high-pressure cell in the South of the Indian Ocean.
- Subtropical jet stream.
- African Easterly jet (Tropical easterly jet)
- Inter-Tropical Convergence Zone (ITCZ)
What type of wind is monsoon?
A monsoon is a seasonal wind system that shifts its direction from summer to winter as the temperature differential changes between land and sea. Monsoons often bring torrential summerrains, such as on the Indian subcontinent where the summer monsoon delivers three-quarters of the country’s annual precipitation.
What is Amihan season?
In the Philippines, Amihan refers to the season dominated by the trade winds, which are experienced in the Philippines as a cool northeast wind. As a rule of thumb, the Philippines’ amihan weather pattern begins sometime in November or December and ends sometime in May or June.
What is known as onset of monsoon?
Explanation: The burst of the monsoon is known as the beginning of the onset of the monsoon and is a phenomenon that involves the sudden changes in the weather conditions and is a characterized by the dry an the wet.
