As the calendar turns to October, the winds shift. The winter monsoon, or "dry monsoon," takes over and lasts through February.
While the experiences the most dramatic version, monsoon systems exist elsewhere:
The delicate balance of the summer and winter monsoons is currently under threat from rising global temperatures. Climate scientists have observed that while the total amount of rainfall during the summer monsoon is becoming more unpredictable, the intensity of individual rain events is increasing. This leads to longer periods of drought followed by "rain bombs" that cause immediate flooding. Additionally, a warming Indian Ocean can weaken the temperature gradient needed to drive the winds, potentially delaying the monsoon's arrival and throwing agricultural cycles into chaos. summer and winter monsoons
The engine driving the monsoon is the disparity in heat capacity between the vast Asian landmass and the surrounding oceans. During the summer months, typically from April to September, the land heats up significantly faster than the water. As the air over the continent rises, it creates a region of low pressure. To fill this void, cool, moisture-laden winds rush in from the high-pressure zones over the Indian Ocean and the southwestern Pacific. This influx of maritime air defines the summer monsoon, known locally in India as the "Southwest Monsoon."
The summer monsoon, often called the "wet monsoon," typically occurs between June and September. In Southern Asia, this is the most anticipated weather event of the year. As the calendar turns to October, the winds shift
Winds blow from the ocean toward the land (Southwest in Asia).
Dictates the rainy season for the Sahel region and West Africa. Climate scientists have observed that while the total
The monsoon cycle is driven by a simple physical principle:
The winter monsoon generally lasts from . As the land cools faster than the sea during winter, the pressure gradient reverses.
While the South Asian monsoon is the most famous, similar patterns occur globally:
