What causes monsoon patterns?
As air rises near the equator and then flows poleward, it leaves an area of fewer air molecules at the equator. Water vapor condenses as air rises and cools in the ITCZ, forming clouds and falling as rain. The ITCZ can be seen from space as a band of clouds around the planet. This is where monsoon rainfall occurs.
What is a monsoon weather pattern?
A monsoon is a large-scale weather pattern that involves a seasonal wind shift over a particular region and is usually accompanied by an increase in atmospheric moisture and precipitation. When this specific weather pattern occurs, the time frame is identified as the “monsoon season.”
How are the monsoon winds formed?
The air over the land gets heated and rises. This causes the winds to flow from the oceans towards the land, which gives rise to Monsoon winds. The pressure difference in adjoining areas gives rise to air movement which leads to the formation of Monsoon winds.
What causes monsoons quizlet?
Monsoons are caused by the fact that the land heats up and cools down faster than water. Thus, in summer, land reaches a higher temperature (high T, low P) than the ocean. Because winds blow from an area of high pressure to an area of low pressure, an extremely constant, moist wind blows from the ocean.
What is monsoon rainfall?
A monsoon is a seasonal change in the direction of the prevailing, or strongest, winds of a region. The summer monsoon and the winter monsoon determine the climate for most of India and Southeast Asia. Summer Monsoon. The summer monsoon is associated with heavy rainfall. It usually happens between April and September.
What causes monsoon winds answer?
The monsoon is caused by the differences in the temperatures of the ocean and continental wind currents. The heat from the sun heat up the oceanic water and results in the generation of air under high pressure that in the form of large air mass undergoes convection and creates low pressure near the surface of land.
What are the mechanisms of monsoon?
Due to Sun, there is differential heating of land and water. The Intertropical Convergence Zone or ITCZ shifts over Ganga plains during the Summer. The high-pressure area, east of Madagascar affects the monsoon.
What causes the monsoon weather pattern of South Asia quizlet?
Monsoon is a seasonal wind pattern in southern Asia. Crossing the water, the wind picks up moisture causing heavy rainfall. Winter Monsoon. Blows from the North and Northeast.
What is monsoons quizlet?
Monsoon. any wind that changes direction with the seasons.
What causes wet and dry seasons?
In many tropical and subtropical regions, rainfall varies much more than temperature does. Also, because the earth tilts, the direct sun rays, and in turn, the tropical rain belt, shifts from the northern to the southern tropics. So these areas experience just two seasons: a wet season and a dry season.
Which is the main cause of Indian rainfall?
34.18 Rainfall during June – September constitutes the rains due to monsoon, which is the major source of rain in India.
What two factors play an important role in the mechanism of the monsoon?
The presence of abundant water bodies around the subcontinent: the Arabian Sea, Bay of Bengal, and Indian Ocean. The presence of abundant highlands like the Western Ghats and the Himalayas right across the path of the southwest monsoon winds.
What causes the rain to fall in the monsoon?
What Causes Monsoons. It’s a cyclic process, as the moisture-filled cool air, which causes rain, leads to loss of moisture and energy. This further causes heating of air, which rises into the atmosphere and returns back to the ocean, where this air releases heat and again gets filled with moisture.
How are monsoons related to the Indian Ocean?
Monsoons are most often associated with the Indian Ocean. Monsoons always blow from cold to warm regions. The summer monsoon and the winter monsoon determine the climate for most of India and Southeast Asia. The summer monsoon is associated with heavy rainfall.
Where are the monsoon winds most often located?
Monsoons are most often associated with the Indian Ocean. Monsoons always blow from cold to warm regions. The summer monsoon and the winter monsoon determine the climate for most of India and Southeast Asia.
What happens to the air when it rains?
It’s a cyclic process, as the moisture-filled cool air, which causes rain, leads to loss of moisture and energy. This further causes heating of air, which rises into the atmosphere and returns back to the ocean, where this air releases heat and again gets filled with moisture.
