What is the annual rainfall in the Mekong River Basin?

The precipitation in Mekong River basin mainly comes from southwest monsoon and northeast monsoon, especially from the southwest monsoon of Indian Ocean. Because the mountains on the east and west sides of the basin are perpendicular to the monsoon wind direction, it is beneficial to the formation of topographic precipitation. The maximum annual rainfall is 2500-3750 mm, and the annual rainfall on the middle and lower reaches and the banks of the delta reaches 1500-2000 mm. The annual rainfall on the Nakhon Ratchasima Plateau in Thailand is slightly less, but it is still 1000-65430 mm. Thus, the annual flow of the Mekong River reaches. The Mekong River has a drainage area almost equal to that of the Danube, and its annual average discharge is almost twice that of the Danube. Mekong River is not only rich in water resources, but also the canyon topography of its main tributaries is conducive to dam building, flood storage and power generation, which can promote the development of industry and mining and the economic development of coastal areas. Mekong river basin belongs to a typical tropical monsoon climate, and is located in the center of Asian tropical monsoon region, with tropical climate characteristics. The annual precipitation is very large, about 2000 mm, and there is more precipitation in the rainy season every year. From May to September, influenced by the southwest monsoon from the Indian Ocean, the weather became rainy and ushered in the annual rainy season, and the air was often humid. From June 1 1 to the middle of March of the following year, affected by the cold northeast monsoon from western Siberia, the weather became dry and rainy, so the dry season came. Throughout the rainy season in the Mekong River basin, rainfall will be very frequent and intense, but it will not last as long as the weather in the east. The duration is short, so the influence range is very small.

Sometimes, in most September, there will be heavy rainfall, which lasts for a long time, and will cause large-scale flood disasters, which will seriously affect people's lives. Moreover, the precipitation in the Mekong River basin is very uneven, and almost every place here will experience different degrees of drought. The reason why the Mekong River basin has a steady stream of water supply is because of the rainy climate here. The runoff here comes from rainfall, and the water level of the Mekong River is basically unchanged by the monsoon, with a large amount of ocean water vapor. It is also a good choice for us to come here and play on the bare beaches and islands in the dry season. We can also shuttle freely on the yacht and enjoy the beautiful scenery of all parts of the Mekong River! The climate of Mekong River is a very important factor to form the beautiful scenery here, which is such a place where the climate has nothing to do with cold. Abundant sunshine, beautiful scenery and suitable temperature are the reasons why Mekong River attracts us!
