Dry Climate


Dry Climate is characterized by less precipitation almost all year round. The Koppen Climate Classification System has accepted dry climate as a part of the World Climatic Regions.

Dry Climate is witnessed by regular evaporation and transpiration that surpasses the level of precipitation. Dry climate is spread along the areas from 20 - 35º North and South of the equator and the continental regions of the mid-latitudes.

Dry climate is further classified into two parts namely dry arid climate and dry semiarid climate. The dry arid (desert) is a climate that envelops almost 12 % of the land surface and is popular for its xerophytic vegetation. The dry semiarid which is also known as steppe is mainly a grassland weather condition which covers 14% of the land surface.

Dry Tropical Climate is usually originated in low-latitude deserts ranging almost 18º to 28º in the hemispheres. It is situated along the center of tropics of Cancer and Capricorn, lying almost north and south of the equator.

Due to the equatorial subtropical high pressure belt and trade winds which evaporates moisture even during intense high temperature. This type of weather is common in places like southwestern United States and northern Mexico; Argentina; North Africa; South Africa; central part of Australia with recoding a temperature of 16º C.

Wet-Dry Tropical Climates is a part of the dry climate which is usually common is areas like India, Indochina, West Africa, southern Africa, South America and the north coast of Australia. This weather is characterized by wet season and dry season simultaneously. It is usually cool at the dry season and quite hot before the wet season.
