Monsoon - Wikipedia
The subtropical flow directs northeasterly winds to blow across southern Asia, creating dry air streams which produce clear skies over India. Meanwhile, a low pressure system known as a monsoon trough develops over South-East Asia and Australasia and …

2024年11月19日 · Monsoon, a major wind system that seasonally reverses its direction—such as one that blows for approximately six months from the northeast and six months from the southwest. The most prominent monsoons occur in South Asia, Africa, Australia, and the Pacific coast of Central America.
What Are Monsoons and Why Do They Happen? - Center for …
Monsoon winds in the tropical parts of North America, Central America, and South America cause the amount of rainfall to vary with the seasons, even in areas where precipitation is plentiful and rainforests thrive.
What Is a Monsoon? | NOAA SciJinks – All About Weather
2024年11月25日 · As the land heats up in the summer, the wind begins to change direction and blows from the south. This new wind blows moist air from the Pacific Ocean and Gulf of California into the region, resulting in thunderstorms and rainfall.
Monsoon Season: What It Is, Causes, and Hazards - ThoughtCo
2019年7月12日 · All winds blow as a result of pressure imbalances between two locations. In the case of monsoons, this pressure imbalance is created when temperatures across vast landmasses such as India and Asia, are significantly warmer or cooler than those over neighboring oceans.
Monsoon - Education | National Geographic Society
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.

2016年7月7日 · Between April and September, warm land temperatures drive pressure patterns and winds that draw in moist air from the Indian Ocean, producing heavy rainfall. During the winter months, the winds move in the opposite direction, blowing cool air over land toward the ocean, leading to very dry conditions.
