Climates of the Eastern Hemisphere

Instructor: Artem Cheprasov
This lesson goes over the many different climate types found in the Eastern Hemisphere using the Koppen climate classification system. This system defines the many different regions of the world based on temperature, rainfall and other climate factors.

Koppen & The Eastern Hemisphere

In the late 1800s, Russian-German climatologist Wladimir Koppen published his work on what is now known as the Koppen climate classification system. It has classified the world's various climates into five distinct types, represented by the letters A, B, C, D and E. This lesson will use each type to describe the various climates of the Eastern Hemisphere.

The Eastern Hemisphere is found east of the Prime Meridian and west of the antemeridian. The Prime Meridian passes through Greenwich, England while the antimeridian passes through the Pacific Ocean, about halfway between Japan and Hawaii.

Type A & B

Type A climates are better known as being humid tropical climates. In the Eastern Hemisphere, much of central Africa has a type A climate. These climates involve a lot of rainfall and have a temperate climate, with the coolest month of the year reaching around 18 degrees C (65 degrees F).

The same can't be said for type B (dry) climates. This climate type is known for little precipitation, sun, and low levels of humidity. The Sahara, the world's largest desert located in Northern Africa, is a good example of this type of climate. Other examples include Baghdad, Iraq and the country of Saudi Arabia.

The Sahara is a great example of a type B climate.

Type C, D, & E

Type C climates are a bit less climatically hostile than many regions that have type B climates. Type C climates have a temperature of at least 10 degrees C (50 degrees F) for the warmest month of the year. During the coldest month of the year the temperature is between -3 degrees C (27 degrees F) and 18 C (64 degrees F). There are many different subtypes of type C climates such as Mediterranean like those found around Israel, Humid Subtropical like the ones near Sydney, Australia and Marine such as the ones found around Copenhagen, Denmark.

Many parts of Israel have what is considered to be a Mediterranean climate.

Type D climates are cooler than type C climates. Type D climates are those that, in part, have a temperature of at least 10 degrees C (50 degrees F) during the warmest month of the year. During the coldest month of the year, temperatures are around -3 degrees C (27 degrees F) or colder. Type D climates can be humid continental in nature like those of Beijing, China, meaning a wide range of temperatures, or continental subarctic, such as Vladivostok, Russia. Continental subarctic regions experience long cold winters and short, cool summers.
