Why did the gale search so many topics this year? What factors are related to strong winds?

Why are there so many topics about strong winds on hot search this year? The reporter learned from the Central Meteorological Observatory that there were 5-7 winds in North China, Northeast China, Huanghuai and other places from the 6th to the 7th, with gusts of 8- 10, and the maximum wind time was from noon on the 6th to daytime on the 7th. The Beijing Meteorological Observatory upgraded and issued a yellow warning of strong wind last night.

At 6 14, the extreme wind speed in some areas of Beijing reached 22. 1 m/s ... The Jilin Provincial Meteorological Observatory also issued a blue gale warning on 6 16. Strong winds also brought dusty weather, and the Central Meteorological Observatory continued to issue a blue warning of sandstorms on the 6th. ? Experts said that the influence range and intensity of windy weather caused by different seasons, climatic backgrounds and weather systems are very different, and strong winds in spring may cause obvious dusty weather. Since the spring of this year, the sandstorm weather in China has been strong, and the total number of sandstorms and strong sandstorms has been the highest since 20 13 years. The windy weather in winter in China is mainly related to cold air activities. If there is strong cold air heading south in the middle and high latitudes of Asia, there will be a large-scale gale cooling or even cold wave weather process in China, which may be accompanied by meteorological disasters such as blizzard and low temperature freezing. Some active small and medium-sized convective systems, such as squall lines and tornadoes in spring and summer, can also cause windy weather. Although the scope of influence is relatively small, the wind intensity is often large, which leads to a greater risk of meteorological disasters, such as April 30 this year. Extreme thunderstorm and windy weather in Jiangsu caused more serious disasters. ? Chen Tao said, in addition, July to 10 is usually the active season for typhoons in the western Pacific. Due to the influence of typhoons, windy weather will also occur in the eastern and southern coasts of China.

Its influence range and wind power are directly related to the typhoon center position, typhoon intensity, typhoon circle radius and other factors. Experts say that windy weather will affect the punctuality and safe operation of roads, railways, planes, ships and other traffic; It may also cause great harm to public outdoor activities, buildings and outdoor facilities; Gale weather will also bring regional floating dust, sand blowing or sandstorm weather, which will affect air quality and visibility. Experts remind the public to pay attention to the forecast and early warning information released by the meteorological department in time. In windy weather, outdoor activities should be avoided as much as possible, safe shelters should be chosen, and fire prevention and falling objects should be paid attention to.
