Geographical environment of Iranian plateau

The Iranian Plateau has a subtropical arid and semi-arid climate, with scarce precipitation, drastic changes in temperature and cold, and large annual range and diurnal temperature range. Most areas belong to subtropical continental grassland and desert climate, with large temperature difference between winter and summer, less rainfall, and most of the water comes from alpine precipitation.

The Iranian Plateau in West Asia is located in the interior of the subtropical continent and belongs to the subtropical continental arid and semi-arid climate. The arid climate is formed because it is far from the sea, because it lives inland or is blocked by mountains, and it is located in the subtropical zone, so it is hot in summer and mild in winter. Semi-arid climate belongs to the type of transition from arid climate to other climate.

The eastern and inland areas of Iran belong to continental subtropical grassland and desert climate, with drastic changes in temperature and cold, hot summer and windy winter, and large areas of grassland, desert and salt marshes are formed inland. The desert area in the east is reduced to about 100 mm, and the mountainous area in the west is affected by the Mediterranean climate, with an average annual precipitation of more than 500 mm, and the average annual precipitation along the Caspian Sea is more than 1000 mm, which is hot and humid and can grow subtropical plants. The vegetation types of Iranian plateau belong to desert grassland, usually xerophytes and gramineous plants, and the soil belongs to semi-desert light brown soil.
