In the past two days, strong rainstorms accompanied by strong convective weather have caused trouble in many places in southern my country. For example, Guangdong, Guangxi and Fujian provinces have encountered more than one heavy rain in the past April. Guangdong has caused many accidents due to heavy rainstorms. For example, the extreme heavy rain in Shenzhen in 411 caused many dredging personnel to be washed away by the sudden flood caused by heavy rain, killing many people. On April 27, a strong rainstorm targeted Taiwan, my country again. The rainfall clouds that erupted on the satellite cloud map were scattering amazing " heavy rain " in many places in Taiwan.
Starting from the early morning of this year, the heavy rainfall in eastern Taiwan of my country began to continue. By 23:10 pm, the cumulative rainfall had reached 510 mm, and the 24-hour rainfall was as high as 525 mm! According to Chinese standards, the 24-hour rainfall exceeds 100 mm is a heavy rain, and more than 250 mm is a heavy rain. Suao undoubtedly suffered an amazing heavy rain, and the rainfall is twice the standard of heavy rain. Guangzhou, which has been quite rainy for this period of time, has a total precipitation in April is less than 400 mm. Suao only took one day to exceed the rainfall in Guangzhou.
In the local area, such heavy rainstorms are also very rare. The original record of 24-hour rainfall in Suao in April was 202.3 mm. Today's strong rainstorms have more than doubled the local daily precipitation record. In addition to Suzhou and Ao, the rainfall in many stations in Yilan, Taiwan today also reached more than 250 mm, which was also a very heavy rainstorm. Today, there were large-scale heavy rainstorms, from heavy rainstorms to even heavy rainstorms on the east coast of Taiwan today.
Does the emergence of heavy rainstorms represent the arrival of Taiwan’s “ plum rain period ”? Because in the general impression, Taiwan only has such violent rainstorms during the plum rain period of the year, but in fact it is not. Judging from the weather map , the subtropical high pressure is still very southerly. The main rain belt in my country is in the Guangxi area of Guangdong, which has led to heavy rainstorms in the Pearl River Delta today. The heavy rain in Taiwan is just the water vapor collected from the East China Sea by cold air, which is caused by rising in front of the central mountain range of Taiwan. In fact, it is essentially a heavy rain caused by the cold air, while the plum rain in is a continuous heavy rain caused by the confrontation of the air mass of with different dew points. Today's heavy rainstorm is very different from plum rain. This cold air is actually the cold air that has previously brought significant cooling and even local "late spring cold" to East China and other places.
supercomputer analysis shows that this kind of heavy rain will often occur in Taiwan in the future. For example, around April 30, strong rainfall will occur again on the east coast of Taiwan. The heavy rain in cold air is so heavy, what if the real plum rain comes in summer? This shows that the recent weather in my country is indeed a bit abnormal, which may be related to the development of El Nino . There may still be a lot of extreme weather in the future, so we must be vigilant.
