Geographic Distribution

• Coastal areas of southwest India,

• Sri Lanka, Bangladesh, Mynamar (Burma),

• Southwestern Africa,

• French Guiana,

• northeast and southeast Brazil.

Controlling Factors

• Summer onshore/winter offshore air movement related to shifting ITCZ or monsoon circulation.

• mE air masses during high-sun; stable mT or cT -> low-sun

Characteristics

• Heavy high-sun rain; short low-sun drought.

• Highest temperature just before rainy period.

Question for thought:

• What's responsible for the two peaks in the temperature curve on the climograph for Mangalore?
