Monsoons in South Asian Countries. Monsoons are seasonal changes in the direction of the wind in a region that causes wet and dry seasons. This phenomenon is most associated with the Indian Ocean where its effects greatly impact South Asian countries. The summer monsoon, which occurs between April and September, brings the wet season.

This monsoon is very strong and has adverse effects on climate in this area (Parker, 2007, p. 1). In this paper, we discuss the causes of the South Asian monsoons and explore their effects on the climate of this region. There exists substantial controversy over the formation of monsoons but one thing is for sure; air pressure is a factor.

The dry season in southeast Asia during the east Asian (EA) winter monsoon is caused by both the decrease in temperature in the north during winter resulting from the cooling of the northern hemisphere and the anti-cyclones caused by the reduced atmospheric pressure.

The rainfall is a result of the convergence of wind flow from the Bay of Bengal and reverse winds from the South China Sea. The onset of the monsoon occurs over the Bay of Bengal in May, arriving at the Indian Peninsula by June, and then the winds move towards the South China Sea.

These rays get reflected and cause warming of the air. This hot air rises up into the atmosphere and the cooler air of the southern hemisphere from the ocean rush to fill the gap. This cool air contains moisture which is the main source of summer rains in Asia. This process is known as summer or southwest monsoon.

How do asian monsoons work?
  • The mechanism affecting the monsoon is that the westerly jet causes high pressure over northern parts of the subcontinent during the winter. This results in the north-to-south flow of the winds in the form of the northeast monsoon. With the northward shift of the vertical sun, this jet shifts north, too.
What causes destruction in monsoons?

As the land's surface becomes warmer, the air above it expands and an area of low pressure develops… As winds blow from the ocean to the land, moist air is brought inland. This is why summer monsoons cause so much rain. Monsoon season does not end as abruptly as it begins.

What causes indian summer monsoons?

The onset of India's summer monsoon is linked to heat differences between the warmer land and cooler ocean, which causes a shift in prevailing wind direction. Winds blow over the Indian Ocean, picking up moisture, which falls as rain over the subcontinent from June to September.

What causes monsoons to form?

In their simplest form, monsoons are caused by differences in temperatures between the oceans and continents. They are most likely to form where a large continental landmass meets a major ocean basin. During the early summer, the landmasses heat up more quickly than ocean waters.

What causes monsoons to happen?

What causes a monsoon? A monsoon (from the Arabic mawsim, which means "season") arises due to a difference in temperatures between a land mass and the adjacent ocean, according to the National Weather Service… The winds reverse again at the end of the monsoon season.

What causes monsoons in ancient india?
