AW Climate Full Form

According to Climatology, AW refers to the Tropical Savanna Climate with winter dry characteristics. The warmest climates are differentiated on the basis of the precipitation of seasonality and they are of the three types mainly :

Af that is no dry season.

Am that is a short dry season.

Aw, that is the winter dry season.

The most used vegetation-based climate classification system is known as Koppen climate classification system. It was created by Wladimir Koppen who was a German botanist. This classification system was developed to derive a formula in order to categorize vegetation zones or bayons according to climatic boundaries. This is a land base classification system in which the Earth is divided into five major types and is represented by the letters A, B, C, D, And E. This system makes use of both precipitation and temperature. This classification system makes the use of both precipitation and temperature. It also makes use of vegetation to categorize the biomes that are present in all the world. This is a good system of classification. There are basically five zones classified based on climatic conditions, these are Zone A, B, C, D, and E.

Zone A

It is called a tropical moist climate zone.

This Zone is present about 150 to 250 latitudes towards the northward and Southward of the Equator; these are tropical and moist climatic zones. The average monthly temperature in this zone is above 18 degrees Celsius throughout the year. The annual rainfall that is present in tropical moist climates is about 1500 millimeters. In this region, we are mainly classified into three types of climatic variations

Af: It is defined as the tropical wet climate. In this area, precipitation occurs year-round.

• The variation in the climate temperature is about 3° Celsius.

• This region is extremely cold and the humidity is extremely high in this region.

• The surface temperature in this area results in the formation of cumulus and clouds in the afternoon time.

• This is the reason that there occurs great rainfall.

Am: It is defined as the tropical Monsoon climate region.

• The annual rainfall is similar to the tropical wet climate.

• The precipitation usually occurs within 7 - 9 the warmest months of the year.

• During the remaining month of the year, there is less precipitation or nearly no precipitation.

Aw: It is termed as tropical wet and also dry climate.

• It is also known as the Savanna climate.

• This is the region of the extended dry season that occurs even during the winter.

• During the wet season here the rainfall is even less than 1,000 mm.

Zone B

These zones are mainly termed dry climatic zones.

A dry climate is dependent upon the nature of precipitation but not on the temperature.

In this type of environment evaporation as well as transpiration exceeds that of the total precipitation.

• This region ranges from 20° to 35° from the north and south of the Equator.

• It is divided into 4 Divisions which are named as- BSh, BWh, BSk, and BWk

There are mainly two different zones that are BS and BW; h and k are the subzones representing hot and cold.

• BW is defined as the dry arid climate and it is considered to be a true desert climate. It covers approximately 12% of the total land of Earth.

• BS represents the type of semi-arid climate. In these regions, grassland is covered and it covers approximately 14% land of the Earth. It receives more rainfall as compared to dry added climate.

Zone C

• It is also termed as moist subtropical mid-latitude climate.

• These are the warm temperate climate regions. In these regions, humid summers and Mild winters can be experienced.

• This type of climate is found in the range of 30° to 50° in the north and south of the Equator.

• These are also mainly seen on the eastern and western sides of the continent.

• In this type of climate thunderstorms can be easily seen but they are seen during summer.

• Cyclones are seen in the winter.

They are further categorized into three zones:

Cw, Cf, and Cs and each zone into three sub-zones of a, b and c.

Zone D

• This type of climate is called the moist Continental mid-latitude climate.

• In this type of climate, summers are warm and Winters are cool.

• They are present towards the pole.

• The average temperature is 10° C in summer and less than -3 degrees Celsius in Winters.

• It is for the job divided into DW, DS, and Df which are further divided into sub-zones of a,b, c and d.

Zone E

This is termed as a polar climatic Zone.

Temperature is very low in this area.

Even during the summer, the temperature is less than 10 degrees Celsius.

It mainly occurs in the northern regions of Asia and North America.

It is divided into ET and EF.

ET refers to the polar tundra. Soil is present in the form of Parma Frost

EF is referred as the polar ice caps they are frozen every time
