Which countries does Central Asia refer to?

Central Asia refers to the countries in the inland areas of Central Asia.

Central Asia is the abbreviation of Central Asia, which refers to the inland areas of Central Asia. This concept was first put forward by German alexander von humboldt in 1843, and its scope has many definitions, generally limited to the narrow sense of "five Central Asian countries". "Five Central Asian countries" refer to Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan and Turkmenistan.

Geographically, Central Asia is located at the junction of Asia and Europe, in the middle of Russian, China, Indian, Iranian, Pakistani and other big countries or regional powers. It is a transportation hub that runs through Asia and Europe. It has always been the only place that passes through the east, west, north and south, and the ancient Silk Road passes through here. After the Cold War, as an important strategic buffer zone, the geopolitical significance of Central Asia has become more prominent.

Climate in Central Asia

Because it is located in the hinterland of Eurasia, especially in the southeast, the mountains block the warm and humid airflow in the Indian Ocean and the Pacific Ocean, and the climate in this area is a typical temperate desert grassland continental climate. Its outstanding features are as follows:

First of all, the rain is scarce and extremely dry. Generally speaking, the annual precipitation is below 300 mm. The annual precipitation in the desert near Aral Sea and Turkmenistan is only 75-1000mm, while the annual precipitation in mountainous areas is1000 mm, and the southern slope of Fergana Mountain can even reach 2000 mm. However, some rainfall in mountainous areas is less than that in desert areas. For example, the annual precipitation in Pamirs is only 60mm.

Second, the mid-latitude mainland is inland, with sunny days, strong solar radiation, high temperature and strong evaporation. Central Asia can get10-130,000 calories per square centimeter of ground every year due to solar radiation, while Turkmenistan almost gets160,000 calories. According to scientific tests, the amount of sunshine obtained in summer at 40 degrees north latitude in Central Asia is not inferior to that in tropical areas. Extremely dry air and high temperature cause a lot of evaporation. The annual evaporation of the water surface in the Amu Darya Delta reaches 1.798 mm, which is 2 1 times larger than the precipitation here.
