Recently, severe convective weather frequently occurred in southern China, and lightning casualties also occurred in Jiangxi, Hainan and other places. In fact, China is a country with frequent lightning disasters, and more than 3000 people are killed or injured by lightning every year. As for lightning, only by understanding it and conducting targeted defense in advance can we minimize the risk.

The first professional lightning forecast APP in China was launched

In order to provide accurate lightning forecast and minimize the impact of lightning on the public, "China Lightning", the first professional lightning forecast APP in China, has been launched.

According to Zhang Guoping, Chief Engineer of the Public Meteorological Service Center of the China Meteorological Administration, this lightning forecasting product has three main characteristics. First, it is more accurate than previous lightning early warning. The public can obtain local lightning forecasting within the next two hours in real time, and the accuracy rate of lightning forecasting in the next 30 minutes has reached 81%.

Second, it is more targeted than traditional lightning warning. As long as you click on China Lightning APP, you can automatically obtain the location and display the local actual situation and forecast. The APP will also overlay the information of surrounding scenic spots, gas stations and parks based on the user's location, so as to make the forecast information and life closer and ensure that users can better prevent risks.

Third, lightning information is more comprehensive. This APP can tell users the local lightning frequency and the date of the highest lightning frequency from 2012 to 2017 through positioning, so as to better understand the law of lightning occurrence and plan travel through big data. In addition, the public can also obtain various popular science videos and animations of lightning protection on APP to intuitively master the tips of lightning protection and risk avoidance.

Big data tells you where you need the "life saving secret script" of thunder and lightning?

China is a country with frequent lightning disasters. According to incomplete statistics, more than 3000 people are killed or injured by lightning every year. According to the big data of lightning from 2014 to 2017 collected by China Weather Network, the "high-risk areas" and "high-risk months" of lightning are regular.

From the perspective of regional characteristics, according to the statistics from 2014 to 2017, Guangdong Pearl River Delta, eastern Sichuan, Shanghai, Zhejiang, Fujian coastal areas, southern Guizhou, northern Hubei and northern Jiangsu are areas with high lightning density. Among them, the number of annual thunderstorm days in Southeast Guangxi, West Guangdong and Hainan is more than 70 days.

2014-2017 National Lightning Density Distribution Map

From the time distribution, the active period of lightning activity in China is from March to September, of which June to August is the high incidence period, especially July to August. Statistics from 2014 to 2017 show that in August, the average number of daily lightning strikes in China reached 79000; In July, the average number of daily lightning strikes in China reached 62000.

Zhang Guoping said that when going out in a thunderstorm, do not get close to electrical equipment such as high-voltage lines, transformers, or stay under trees. Stay away from open places, and do not answer or make calls in a thunderstorm. When people are in open areas, mountains, balconies, roofs, under trees, open boats and other places, they may encounter lightning attacks, so the best way is to stay indoors, close doors and windows and wait for the thunderstorm weather to end; When a friend happens to be outdoors in a thunderstorm, he or she can choose nearby stores, restaurants and other buildings to take shelter.

Experts remind that at present, China has entered an active period of lightning activities, and the public must pay attention to lightning forecast. You can download and install the "China Lightning" APP at the following address to do a good job in defense in advance.
