Question

what are the main character of tropical monsoon type of climate

Answer 1

A Tropical monsoon climate (occasionally known as a tropical wet climate or a tropical monsoon and trade-wind littoral climate ) is a type of climate that corresponds to the Köppen climate classification category "Am". Tropical monsoon climates have monthly mean temperatures above 18 °C in every month of the year and feature wet and dry seasons, as
Tropical savanna climates do.
Tropical monsoon climates however features its driest month seeing on average less than 60 mm but more than 100 – [total annual precipitation {mm}/25] of precipitation. [1]
:200–1 This latter fact is in direct contrast to a tropical savanna climate, whose driest month sees less than 60 mm of precipitation and also
less than 100 – [total annual precipitation {mm}/25] of precipitation. In essence, a tropical monsoon climate tends to either see more rainfall than a tropical savanna climate or have less pronounced dry seasons. Additionally, a tropical monsoon climate tends to see less variance in temperatures during the course of the year than a tropical savanna climate. This climate has a driest month which nearly always occurs at or soon after the "winter" solstice for that side of the equator.
