Where is the strongest storm in the world?

1On August 4th, 975, Typhoon No.3 in China ("Typhoon No.7503") made landfall in Jinjiang, Fujian after crossing the island of Taiwan Province Province. At this time, just as the air near Australia in the southern hemisphere broke out in the northern hemisphere, the tropical convergence line of the western Pacific jumped northward, causing the landing typhoon not to disappear quickly on land as usual, but to cross Jiangxi, Hunan, Changde and the Yangtze River with rare intensity and suddenly reach the hinterland of the Central Plains. On August 5, the mysterious typhoon 7503 suddenly disappeared from the radar monitoring screen of Beijing Central Meteorological Observatory. Due to the adjustment of the westerly belt in the northern hemisphere, Typhoon No.7503 could not turn eastward on its way northward, so "stop and move less in Henan" led to the disaster. The specific area of "stagnation" is in the big arc zone between Funiu Mountain Range and Tongbai Mountain Range, where there are a large number of horseshoe-shaped valleys surrounded by mountains on three sides and canyons sandwiched between the two mountains. The southerly airflow moves violently vertically here, and with the participation of other weather scale systems, it causes a rare rainstorm in history. This area, which is most prone to rainstorm, is also the best area to build reservoirs-hundreds of mountain reservoirs are scattered here. The rainstorm was unexpected by the reservoir designer. From August 4th to August 8th, the maximum rainfall in the rainstorm center reached 163 1mm, and the maximum rainfall for three days (August 5th to 7th) was 1605mm. The strongest rain belt is located on the windward side of Funiu Mountain Range. From 4th to 8th, the rainfall area over 400 mm reached 194 10 km2. The precipitation area greater than 1000mm is concentrated in Banqiao Reservoir and Shimantan Reservoir to Fangcheng, west of Beijing-Guangzhou Railway. The rainfall intensity of this rainstorm, in the rainstorm center-Banqiao Reservoir Zhuang Lin, the maximum 6-hour rainfall was 830mm, which exceeded the world record at that time (782mm maximum 24-hour rainfall 1060mm in Smith Port, Pennsylvania, USA, and also set the highest record of similar indicators in China. Witnesses said: within a few days of heavy rain, day is like night; Rain is like shooting from a fire hose; Take out the washbasin from the room and it will be full in a blink of an eye; The rain was like an arrow, and there were dead birds everywhere on the mountain after the rain. This extraordinary typhoon brought unprecedented disaster to Henan. Two large reservoirs, Banqiao and Shimantan in Zhumadian, Henan Province, as well as two medium-sized reservoirs and 58 small reservoirs, were dam-broken in just a few hours. The flood of 5.7 billion cubic meters turned Zhumadian 10 county (town) into Zeguo. Adding Xuchang, Zhoukou and Nanyang, the number of people affected was 165438+. Qian, then Minister of Water Resources and Electric Power, said: This is the largest flood with the largest affected area and the largest number of deaths since the founding of the People's Republic of China, and it is the most painful lesson of water conservancy work. In addition, affected by Typhoon No.7503, Fujian, Jiangxi, Hunan, Hubei, Anhui and other provinces were also affected to varying degrees. 5.39 million mu of farmland was affected, 208 people were killed, more than 560 people were injured and more than 60,000 houses collapsed.
