What is the cause of tropical monsoon climate?

Question 1: What are the causes of tropical monsoon climate? The winter monsoon in tropical monsoon climate is formed by the difference of thermal properties between land and sea, and the summer monsoon is mainly formed by the seasonal movement of pressure zone and wind zone.

Question 2: Reasons for the formation of the south subtropical monsoon climate In winter, South Asia is affected by the northeast winds from Mongolia and Siberia, forming a dry season; In summer, the pressure belt winds move northward, and the southeast trade winds in the southern hemisphere deflect across the equator into southwest monsoon, which affects South Asia and forms the rainy season.

The winter monsoon in South Asia is caused by the thermal difference between land and sea, and the summer monsoon is caused by the seasonal movement of the position of the wind belt in the pressure belt.

Question 3: The main reasons for the formation of tropical monsoon climate are mainly distributed in the South Asian subcontinent and the northern Indo-China Peninsula, which are related to the huge thermal gap between land and sea and the seasonal movement of the pressure belt.

In winter, there is a strong cold high in the Asian continent, which is the Mongolian high, while the Indian subcontinent and Indochina Peninsula are at the bottom of the Mongolian high. In winter, the cold source of the Qinghai-Tibet Plateau promotes the formation of the northeast monsoon.

In summer, there is a low pressure near thar desert, India, which is the Indian low pressure, while the Indian subcontinent has a southwest wind at the front and bottom of the low pressure. Coupled with the summer heat source of the Qinghai-Tibet Plateau and the northward movement of the equatorial low pressure belt, the southeast trade wind from the southern hemisphere passes through the equator and becomes the southwest monsoon formed by the thermal action of land and sea, forming the strongest monsoon southwest monsoon in South Asia and Southeast Asia.

Question 4: Tropical monsoon climate causes The tropical monsoon climate is mainly distributed in the South Asian subcontinent and the northern part of Indochina Peninsula. The reason is related to the huge thermal gap between land and sea and the seasonal movement of pressure zone. There is a strong cold high in the Asian continent in winter, that is, the Mongolian high, while the Indian subcontinent and Indochina Peninsula are at the bottom of the Mongolian high, plus the cold source effect of the Qinghai-Tibet Plateau in winter. In summer, there is a low pressure near thar desert, India, which is the Indian low pressure, while the Indian subcontinent has a southwest wind at the front and bottom of the low pressure. Coupled with the summer heat source of the Qinghai-Tibet Plateau and the northward movement of the equatorial low pressure belt, the southeast trade wind from the southern hemisphere passes through the equator and becomes the southwest monsoon formed by the thermal action of land and sea, forming the strongest monsoon southwest monsoon in South Asia and Southeast Asia.

Question 5: The causes of the south subtropical monsoon climate;

Winter: Due to the different specific heat capacities of land and sea between Asia and Europe and the Pacific Ocean, the continental temperature is low, the air contracts and sinks, and the air pressure rises. Especially, there is a strong high pressure center in Mongolia-Siberia region at high latitude. On the contrary, there is a pressure difference between land and sea. Under the action of Gongping pressure gradient force, the wind blows from land to sea (the airflow on the same horizontal plane always blows from high pressure to low pressure, and the force that urges the horizontal airflow to blow from high pressure to low pressure is called horizontal pressure gradient force. However, under the action of geostrophic bias, the wind does not blow directly to the ocean, but constantly deflects to the right. Therefore, the east coast of Eurasia is controlled by the north wind in winter, because winter is blown from the high-latitude continent, so it is cold and dry. The real north wind has turned to the northeast wind when it reaches South Asia. The northern part of South Asia is blocked by mountains and the terrain is blocked, which is located on the leeward slope of winter wind. In winter, the wind has the function of burning wind, making it hot and dry. In addition, its latitude is low, and the height of the sun is actually high in winter, so the temperature is high in winter and there is little rain.

Simply put, the cause of the winter monsoon in South Asia: the difference of thermal properties between land and sea. Climate characteristics: high temperature and little rain.

Summer: The southeast trade wind, which should have appeared in the southern hemisphere, moves northward with the direct point of the sun, extending its control area to the northern hemisphere. At this time, due to the different thermal properties of land and sea, a low pressure center appeared near South Asia, and the southeast trade winds continued to move northward. However, due to the influence of geostrophic deflection in the northern hemisphere, the direction of the southeast trade wind is constantly changing to the southwest wind. The southwest monsoon actually blows from the low-latitude ocean, so it is controlled by it to have high temperature and rainy weather in South Asia.

Simply put, the cause of the South Asian summer monsoon: the pressure belt wind belt moves with the season. Climate characteristics: hot and humid.
