Thunderstorms, strong winds and hail may occur in 9 provinces of China. Where are these nine provinces?

Hail is a natural weather and an inevitable phenomenon. Hail is a kind of ice falling from a strong cumulonimbus cloud. More common in summer or at the turn of spring and summer. When hail occurs, it is often accompanied by strong winds, severe cooling and strong lightning. Next, let's talk about it. There may be thunderstorms and hail in nine provinces of China. Where are these nine provinces?

The Central Meteorological Observatory of 9 provinces continued to issue a blue warning of severe convective weather at 06: 00 on May 14: It is expected that there will be 8- 10 thunderstorm or hail weather in parts of southern Inner Mongolia, south-central Shaanxi, southern Henan, south-central Anhui, south-central Jiangsu, northern Shanghai, northern and western Hubei, northwestern Jiangxi and northern Zhejiang.

There will be short-term heavy rainfall in parts of central Inner Mongolia, northwestern Heilongjiang, southern Henan, central and southern Anhui, central and southern Jiangsu, northern Shanghai, Hubei, northern Hunan, northern and southern Jiangxi, northern Zhejiang, northeastern Sichuan Basin, northeastern Chongqing, northeastern Guangxi, central and northwestern Guangdong, with hourly rainfall intensity of 20-50 mm and local area of 70 mm or more.

The Central Meteorological Observatory continued to issue a blue rainstorm warning at 06: 00 on May 15: It is estimated that there will be heavy rainstorms in parts of Shanxi, eastern Shaanxi, western and southern Henan, eastern Chongqing, Hubei, Anhui, Jiangsu, western and northern Hunan, northwestern Jiangxi, eastern Guizhou and southeastern Tibet, among which there will be heavy rainstorms in eastern Hubei, northern Hunan, southeastern Anhui and southern Jiangsu. Heavy rain (100 ~ 130mm). Some of the above areas are accompanied by short-term heavy rainfall, with an hourly rainfall of 20 ~ 40 mm, and the local area can reach more than 60 mm. The local area is accompanied by strong convective weather such as thunderstorms or hail. How to prevent hail weather?

What should I do if I encounter hail? Hail is most common in summer or at the turn of spring and summer. Sometimes it is as small as mung beans and soybeans, and sometimes it is as big as chestnuts and eggs. Heavy hail is bigger than grapefruit. Once the hail falls, the impact is not small. Generally speaking, hail with a diameter of about 5 cm is the "egg-sized hail" often mentioned in the news, weighing about 30 grams.

According to the law of conservation of energy, when it falls to the ground from a height of 1000m, an object weighing 3 kg falls from a height of about 10m, which is almost equivalent to throwing a flowerpot with soil from a three-story height and hitting people or cars ... this is just hail. If we encounter hail outdoors, it may be that several flower pots fall from the sky. Therefore, when encountering hail, we must not take it lightly.

What should I do if I encounter lightning? In thunderstorm weather, attention should be paid to closing doors and windows, cutting off the power supply of indoor appliances, and pulling out outdoor antennas to install lightning arresters; Do not touch gas pipelines, tap water pipelines and all kinds of live equipment; It is best to wear a raincoat made of plastic outdoors in thunderstorm weather. If possible, you can enter a building with a wide metal frame or lightning protection measures. If you are sheltering from the rain on a street sheltered by buildings or tall trees, you should pay attention to leaving the wall and trunk 8 meters away.

When indoors, stay away from lighting lines, telephone lines, broadcasting lines, TV antennas and various conductors connected with them to prevent the secondary discharge of these lines and conductors to the human body; When there is lightning, it is best for the human body to leave the lines and conductors 1.5 meters where lightning intrusion waves may come.

In addition, doors and windows should be closed to avoid through flow and prevent ball lightning from entering the room and hurting people. When there is lightning, thunder and rain, indoor TV, tape recorder, stereo, air conditioner and other electrical appliances should be turned off immediately to avoid conduction.
