Historical weather in Taizhou City, Zhejiang Province

In 2006, Typhoon Sang Mei caused serious damage to the power grid and equipment in Wenzhou, Zhejiang and Fuding, Fujian. Wenzhou Power Grid * * alone caused 500 kV lines to trip 8 times, 220 kV lines to trip 5 times, 1 10 kV lines to trip 40 times, 35 kV lines to trip 42 times, and 10 kV lines to trip 3 times18 times. The typhoon caused 3 poles to fall on 220kV lines and 98 poles to fall on110kV lines. At the same time, a 1 10 kV main transformer was damaged; Two 35kV substations were destroyed. According to incomplete statistics, the direct economic loss caused by typhoon to Wenzhou power grid is nearly 200 million yuan.

Typhoon is a general term for tropical cyclones, the most destructive large-scale weather system and one of the most terrible natural disasters. According to the report, since 128 1, there have been seven catastrophes in the northern hemisphere * *, which caused more than 654.38+million deaths, including four with more than 300,000 deaths. ? Taizhou, located in the southeast coast of China and the west coast of the northwest Pacific Ocean, is the place with the most frequent typhoon activities. Surrounded by mountains in the northwest and the sea in the southeast, the terrain is inclined from west to east, which is beneficial to the uplift and convergence of heavy rain in the east. It has always been a place where typhoons frequently hit. Huangwen Plain is near the sea, with low terrain, and its northeast is connected with the sea to the south, which is beneficial to the southeast wind to attack and maintain; Taizhou Bay belongs to trumpet-shaped ultra-shallow sea estuary, which is very suitable for strengthening the eastward storm surge. Because of its special geographical location and landform, Taizhou has become the most serious typhoon disaster area in Zhejiang Province and even the whole country. Typhoon has become an important factor restricting Taizhou's economic and social development. Therefore, doing a good job in typhoon prevention is not only related to the life and property safety of thousands of people in Taizhou, Qian Qian, but also directly related to the current and future economic and social development of Taizhou. ?

1. What is the general situation of typhoons affecting Taizhou?

According to historical records (local chronicles, etc. ), Taizhou was frequently hit by strong typhoons in history. From 1000 to before the founding of the People's Republic of China, there were no fewer than ten disasters in Taiwan Province with more than 10,000 deaths. ? In the 56 years since the founding of the People's Republic of China (1950 ~ 2005), the total number of tropical cyclones in the northwest Pacific (including tropical storms, severe tropical storms and typhoons, collectively referred to as "typhoons") is about 1540, of which 23 1 affects Taizhou, with an average of 4./kloc-per year. There are 18 typhoons landing directly on the coast of Taizhou (every three years on average), accounting for 50% of the total number of typhoons landing in Zhejiang Province (there are 1 3 typhoons landing on the coast of Wenzhou in the same period). Most typhoons that landed in Taizhou (6 1%) can reach 12 or above, and most of them (6 1%) have caused serious disasters. ?

Generally speaking, compared with before the founding of the People's Republic of China, the number of deaths caused by typhoons in the whole province has dropped significantly, with less than 200 people except for typhoons 5207, 56/KOOC-0/2, 6/KOOC-0/26 and 94/KOOC-0/7. Since the new century, under the guiding ideology of "people-oriented" typhoon prevention, except for Typhoon Yunna 04 14 and Typhoon Sang Mei 0608, the death toll has dropped to less than 18, and even no death record has been created, which has protected people's lives and property to the maximum extent. ? The distribution of typhoons affecting Taizhou can be seen from May to 65438+February, and nearly 80% (78%) of them affect Taizhou from July to September. Typhoon landed in Taizhou in July-65438+1 October, of which July and August were the most frequent (7 times each, accounting for 39%), followed by September (***3 times, accounting for 17%), and only/kloc in June-65438+1October. However, a typhoon (No.6104) landed near Yueqing in late May. Report to the authorities
