China's weather net inventory of meteorological big data, revealing which places in my country are the most frequent thunderstorms and when it is the most active.

How did thunderstorms formed?

Thunderstorm is a natural phenomenon, which is the local strong convective weather that occurs in tropical and temperate regions. It is generated by the stream of streaming rainy clouds. Due to the strong development of the Yiyun, it is often accompanied by lightning, thunder, heavy rain, and wind, and sometimes disaster weather such as hail, tornado, and storms.

Where is the most likely to "encounter thunder" in the nationwide thunderstorm map

In terms of meteorology, an observation station heard the thunder observation day as a thunderstorm day. China Weather Network studied big data from thunderstorms from 1981 to 2013 to find that there are more likely thunderstorms in southern my country than north, and there are more thunderstorm days than the plain.

From the national thunderstorm map released by China Weather Network, it can be seen that the areas with the highest thunderstorms in my country are in southern Yunnan, Hainan, most of Guangdong, southeast of Guangxi, and parts of the central Tibet. The land exceeds 100 days; the average number of thunderstorm days in the west of Yunnan, west of Guangxi and north, Jiangxi, Fujian, and southern Zhejiang is between 50-70 days.

Most of Zhejiang, central and southern Anhui, Hunan, Chongqing, Guizhou, western and southern Sichuan, Shanxi, Beijing, northern Hebei, Jilin, eastern Qinghai, and western Xinjiang are between 30-50 days. Most of the northwest region, Inner Mongolia and Huanghuai Plain are areas with lower thunderstorms. The average annual thunderstorm is less than 30 days.

The most easy to encounter a thunderstorm city ranking is released

Haikou Leading

Among the provincial -level cities, Haikou, Guangzhou, Lhasa, Nanning, Kunming and other places are more prone to thunderstorms. The highest number of thunderstorms in Haikou reaches 83.6 days, and thunderstorms will occur almost every 4 days. Guangzhou and Lhasa followed closely with 73.1 days and 69.1 days, ranking two or three; Urumqi, Xi'an, Yinchuan, Lanzhou and other places have a low probability of "Wen Lei", and the lowest Urumqi annual thunderstorm is less than 5 days.

Thunderstorm prefers summer "punch card"

The highest afternoon afternoon

my country is vast, and thunderstorms occur in various places sooner or later. As far as the national average situation is concerned, there are obvious seasonal differences in thunderstorms. Summer is a high incidence period, and it rarely occurs in winter. The low probability of "Wen Lei" in winter can even find confirmation from ancient poems. In the Hanlefu folk song "Shangxie", there is a poem "Winter Lei shocks summer rain and snow, the heaven and earth, but dare to be with the monarch!"

From the perspective of the number of thunderstorm days by month by month, my country's thunderstorms mainly occur from April to September. Among them, the highest peak in July, reaching 8.5 days, basically thunderstorms may occur every 4 days, and from November to February of the following year There are almost no thunderstorms across the country, with an average number of days less than 0.5 days.

Shi Yan, a meteorological analyst of China Weather Network, introduced that the peak of thunderstorms in my country is mainly from June to August, which is closely related to the current weather. At this time, after the outbreak of the summer wind in the south, the warm and humid airflow became more enhanced and the weather was more likely to appear. In the north, due to the frequent activity of the cold vortex in the northeast, the number of streams in North China and Northeast China increased, and the number of thunderstorms was more. After September, the rainy season in the northeast and North China of my country ended, and the number of thunderstorms declined significantly; in the south, with the retreat of the southwest monsoon, the warm and humid air flow decreased, the temperature decreased, and the probability of thunderstorms also decreased rapidly.

During the day, thunderstorms in all parts of my country are generally concentrated in the afternoon to the evening, and the highest peak at 15:00 to 17:00. According to statistics from the Chinese Academy of Meteorological Sciences, in the 10 years from 1997 to 2006, the daily change characteristics of thunderstorms showed a typical single -peak type, which began to rise rapidly at 13:00, and reached a high value at 15:00 to 17:00. It reached the peak at 16:00, accounting for 17.1%.

China Weather Network reminds everyone that it is usually easier to encounter lightning attacks such as empty zones, mountains, balconies, roofs, under trees, convertibles, etc., and minimize outing as much as possible. Close the doors and windows at home and wait for thunderstorms to end. Friends who are outside the outdoors during thunderstorms. Do not avoid rain under the big trees. You can choose buildings such as shops, restaurants and other buildings to avoid, do not answer calls, close to electric equipment, etc. to avoid lightning strikes.
