Differences in weather around the world

1. What are the characteristics and causes of the Asian climate?

Features: (1) The zonality is complete and the types are diverse (10 species). Lack of tropical grassland climate and temperate maritime climate

(2) The monsoon climate is typical and extensive. (East Asian monsoon, South Asian monsoon)

(3) The mainland is remarkable and the drought range is wide.

Origin: (1) Geographical location:

A. Latitude position:1o17 ˊ n ~ 77o43 ˊ n.

B. Land and sea location: Eurasia faces the ocean in the east, the European continent in the west, the Indian Ocean in the south and the Arctic Ocean in the north.

(2) Contour and area:

The outline is complete and the area is huge (44 million square kilometers), which makes the land conditions and land-sea position differences between coastal areas and inland areas distributed in a strip shape. The central part (Lan Tu Plain) is controlled by continental air mass all the year round, and the climate is cold and dry.

(3) Terrain:

A Pamir-Qinghai-Tibet Plateau is the center, and mountains extend in three directions (mountains play a barrier role).

West Asia: East-west mountain range, blocking the southern airflow from going deep inland.

East Asia: north-south trend, blocking the eastern airflow from going deep inland.

B. Qinghai-Tibet Plateau-make the branches of the westerly belt (south and north) meet on the east side of the Qinghai-Tibet Plateau, and the west of the meeting point is the "dead water area", where the east wind is strong.

(4) Ocean current:

Kuroshio warm current (the eastern ocean of the mainland), tidal cold current (the northern part of the Japanese archipelago) and Indian Ocean monsoon drift (bringing abundant rainfall to Indochina Peninsula).

(5) Atmospheric circulation:

Atmospheric activity centers affecting Asia;

Winter: Mongolian high (Siberian high) and Aleutian low;

Summer: India low pressure, Hawaii high pressure.

The air masses affecting Asia are: Pc (polar continental air mass), Pm (polar marine air mass), Tc (tropical continental air mass), Tm (tropical marine air mass), Ac (glacial continental air mass), Am (glacial marine air mass) and E (equatorial air mass).
