Q

How does the STAC influence the wet season?

A

The descending air travels back to the ITCZ as easterly trade winds that pick up the needed moisture form the Indian Ocean

Q

Describe the temperature, rainfall, winds, humidity and TRS in the dry season of the monsoon climate?

A

Temperature: Decreased but still hot temperatures (15-23 Celsius)
Rainfall: Little
Winds: Weak
Humidity: Less intense because TW are offshore
TRS: More

Q

How does the ITCZ affect the dry monsoon season?

A

Winds now blow offshore so less humidity

Changes the position of the important STAC and other influences

Q

How does the STAC affect the dry monsoon climate?

A

It creates an area of high pressure which creates the associated weather and can lead to droughts

16
Q

How does the STJS affect the dry monsoon climate?

A

It can bring western weather systems such as valuable depressions due to droughts to India

17
Q

How does the ocean and TRS affect the dry monsoon climate?

A

It can bring more TRS to the area that brings the weather

18
Q

What does climate change threaten the monsoon climate?

A

Divert the ITCZ away from India drastically changing the whole annual climate
Dry season: Warmer oceans means more TRS. It may also make the STAC even drier

19
Q

What is currently the most important factor in the monsoon climate?

A

ITCZ because it affects all other influences
