What is the biggest rain in the history of China?

In the fire known as China Rain Pole. 19 12 The maximum rainfall is 8409mm.

According to the statistics of1906-1944 for 38 years, the average annual precipitation in this area is 6557.8 mm, and there are many days of precipitation, with an average annual precipitation of 2 14 days. So much precipitation in Huoshaoliao is formed by its unique geographical location and topography, which is closely combined with northeast monsoon rainfall, southeast monsoon rainfall, thunderstorm and typhoon rainstorm.

Extended data:

Burning flame:

Huoshaoliao is located on the windward side of the junction of Keelung, Taipei and Yilan. Except for the high altitude in the southwest, the topography in the west, north, east and southeast gradually inclines outward, which is beneficial to the formation of topographic precipitation. Every year, typhoons in summer and autumn, northeast monsoon in winter and southeast monsoon in summer will form topographic precipitation here.

Another kind of fire is the only way of summer monsoon, which is deeply influenced by summer monsoon. Therefore, the northeast monsoon from September to March every year carries a lot of water vapor south, where it is intercepted by the terrain to form dense rain.

Every summer and autumn, the instantaneous rainfall of typhoons is even more amazing, so it is called the "rainstorm center" of Taiwan Province, and it is the area with the largest annual rainfall in China. Now Huoshaoliao is in danger of being submerged by the planned Pingxi Reservoir.

Climatic rainfall:

The reason why Huoshaoliao has become the most rainy area in China is mainly caused by geographical location, topography, winter and summer monsoon, typhoon and other factors. Huoshaoliao is located on a hillside 420 meters above sea level at the northeast end of Taiwan Province mountain range, facing the sea.

In summer and autumn, the humid summer monsoon and typhoon blowing from the southeast sea are lifted by the terrain when landing, and the precipitation is abundant; Winter is also affected by the northeast monsoon. Because the northeast monsoon passes through the vast ocean, especially after passing through the warm water surface of Kuroshio, the water vapor increases sharply. When the airflow reached Huoshaoliao, it was lifted by the terrain, resulting in a lot of precipitation.

According to statistics, from June 1 1 to March of the following year, the winter precipitation in Huoshaoliao accounts for half of the total annual precipitation. Because there is a lot of precipitation in both winter and summer, burning the fire has become the "rain pole" in China.

Rainfall measurement:

Rainfall is generally measured by rainfall pipes, so it may contain a small amount of dew, frost and pine branches. Meteorology, there is always precipitation in years, months, days, 12 hours, 6 hours or even 1 hour, and all the rain and snow falling within 6 hours melt into water, which is called 6-hour precipitation; All the rain and snow falling within 24 hours melt into water, which is called 24-hour precipitation.

A ten-day rain and snow melt into water, which is called ten-day precipitation ... In a year, all the rain and snow melt into water, which is called "annual precipitation". Liquid precipitation is called rainfall, and sometimes the two are synonymous. The precipitation per unit time is called precipitation intensity, usually in millimeters per hour or millimeters per minute. The rainfall per unit time is called rainfall intensity.

The average annual rainfall of a place for many years is called the "average annual rainfall" of this place. For example, the average annual rainfall in Beijing is 532.0mm, and that in Shanghai is1166.1mm. ..

Precipitation refers to a weather phenomenon in which liquid water or solid water falls to the ground. Accurate measurement of precipitation is of great significance for weather forecast, climate analysis, monitoring and early warning of natural disasters such as floods, landslides and mudslides.
