Thar Desert Desert in southeastern Pakistan. To the east of the Indus and Sutlej rivers is the extension of the Indian Desert. It covers an area of ??about 200,000 square kilometers. Sand dunes are generally 30-90 meters high, with a maximum height of 150 meters. The climate is dry and hot, the hottest month in summer is 48-51℃, and the annual rainfall is 150-250 mm. There are severe dust storms from May to June. There are seasonal salt lakes and dry river beds, with only deep water available. Most residents are engaged in animal husbandry. Produces wheat, millet, cotton, etc.
The formation of the Indian desert is due to the subtropical high pressure, which causes the air to sink and heat up, which blocks surface convection and makes it difficult for rain to occur. In addition, the wind and airflow from the western desert first pass through the arid plateau of Afghanistan and Baluchistan, and cannot cause rain when it descends to this area. The monsoon winds that go up the Ganges from the east lose water vapor along the way, and then descend to Punjab, and the air sinks. Increased temperature cannot cause rain.
