What winds prevail in Indochina? Causes

Indochina. The northeast monsoon and the southwest monsoon prevail.

Reason: The northwest monsoon formed by the difference in thermal properties between land and sea in winter is affected by geostrophic deflection forces during its southward movement.

when it reaches Indochina, it deflects into the northeast monsoon; In summer, due to the seasonal movement of the position of the pressure zone and the wind belt, the southeast trade winds from the southern hemisphere cross the equator northward and deflect into the southwest monsoon under the influence of geostrophic deflection forces.

In winter, northeasterly winds from the continent prevail with little precipitation, and in summer, southwesterly winds from the Indian Ocean prevail with abundant precipitation, with annual precipitation of 1500-2000 mm in most areas, but in some areas there are much more than that. The average annual precipitation is affected by the topography, reaching 5000 mm on the windward side and less than 2000 mm on the leeward side. Individual windward slopes and areas of the Malay Peninsula can form tropical rainforest landscapes, while a few inner plains and river valleys form savannahs.

Peculiarity. 1. High temperature all year round, the average annual temperature is above 22, and the coldest month is generally above 16 in the winter half of the year. In Xishuangbanna in Yunnan Province and southern India, the high mountains and plateaus in the north block the southward invasion of cold air, making the temperature in the region relatively high in the winter half of the year.

2. The annual precipitation is large, the dry and rainy season is obvious, and the precipitation is concentrated in summer. In summer, under the control of the equatorial ocean air mass, there is a lot of convective rain, coupled with a large amount of precipitation brought by the passage of tropical cyclones, so it causes more summer rain than the tropical dry and wet season climate. On some windward coasts, summer precipitation even exceeds that of equatorial rainy climate zones due to topography. Annual precipitation is generally above 1500 to 2000 mm.

The hot and humid climate of this region, abundant water vapor, and special topography have created the world's "rain pole" - Qirapunzi. In winter, precipitation is scarce under the control of the dry northeast monsoon.

The northeast and southwest monsoons prevail in Indochina.

Reason: The northwest monsoon formed by the difference in thermal properties of land and sea in winter is affected by the geostrophic deflection force during the southward movement, and deflects to the northeast monsoon when it reaches the Indochina Peninsula. In summer, due to the seasonal movement of the position of the pressure zone and the wind belt, the southeast trade winds from the southern hemisphere cross the equator northward and deflect into the southwest monsoon under the influence of geostrophic deflection forces.

Indochina has a tropical monsoon climate, with southwesterly winds prevailing in summer (influenced by the southwest monsoon from the Indian Ocean).

Southwest monsoon, if you don't believe it, go through the geography textbook of the first year of junior high school and check it.

First of all, this issue has nothing to do with the military, but with geography.

Secondly, the Indochina Peninsula has little to do with the Somali sea - one in the south of our country and one in the western part of Asia.

It is only related to time, December 9, 2009, it is winter.

Indochina has a tropical monsoon climate, during which the winter monsoon blows – the winter monsoon is northeasterly.

March and May are the hot season, the winter and summer monsoon have subsided, the climate is hot, and the average monthly temperature reaches 25 30; The year is divided into two seasons, dry and rainy, June and October is the rainy season, the southwest monsoon prevails, and the precipitation is abundant; November The following February is the dry season, the northeast monsoon prevails, and the weather is dry and rainless. Climatic characteristics: high temperature throughout the year, precipitation is concentrated in summer.

In summer, it is related to the air pressure, which is the point where the air pressure shines directly with the sun.

The wind blows from the south to the north, but the wind direction is affected by the earth's gravity, and it is biased to the right, forming the southwest monsoon, and in winter, the Mongolian Siberian depression.

Moving southward, the wind is blown from being blown to the south, and under the influence of the left-sided gravity of the Northern Hemisphere, the wind direction is biased to the left, forming the northeast monsoon.

The summer monsoon is due to the fact that summer in the Northern Hemisphere is winter in the Southern Hemisphere. Due to the difference in the thermal properties of land and sea, the land cools faster than the ocean, creating a high pressure over the Australian continent. The northern hemisphere is summer, which is also due to the difference in the thermal properties of the land and the sea, and the land in the northern hemisphere is low pressure.

And because the air is blown by high pressure and low pressure.

Therefore, there is a southerly blowing from south to north, southeast wind in the southern hemisphere, passing through the equator to the northern hemisphere, subject to geostrophic deflection force.

The influence turned into a southwest wind.

Indochina Peninsula, the Indian Peninsula has a prevalent southwesterly wind in summer. It is a tropical monsoon climate!

One is the southeast monsoon and the other is the southwest monsoon.
