Hails have devastated Guangdong since April, and meteorologists say “more than average in previous yearsâ€
I have never seen such hail
Since April, thunderstorms and other strong convective weather have frequently ravaged Guangdong, and it is particularly evident that there have been many hailfalls in the sky, north to Shaoguan and south to Zhanjiang, and the scope of influence is quite extensive. Many residents of Guangdong shouted: They dare not drive, fear being worn by the ice, but they dare not go out and fear being beaten! "The number of occurrences of hailstorms in April this year was indeed too high!" said Wu Zhifang, chief forecaster of the Guangdong Provincial Meteorological Observatory, echoing the sighs of many people.
More hail weather
Wu Zhifang, the chief forecaster of the Guangdong Provincial Meteorological Observatory, told the Yangcheng Evening News that since April 5th, Guangdong province has experienced frequent thunderstorms, hailstorms, tornadoes, strong thunderstorms, and strong short-term precipitation, especially on the 12th. On the 19th, strong convective weather occurred in 7 out of 8 days, which is rare.
Not to mention the thunderstorms and tornadoes that appeared in various places. From hail alone, from 5th to 6th, records of hail were recorded in Xuwen County, Zhanjiang; on the 12th, hail occurred in Qingyuan Qingyuan County and Huadu District of Guangzhou in the evening, and Shaoguan Lechang. Late afternoon in the Qinglian Sanlian area, there was hail; on the afternoon of the 13th, there was a short ice storm in Panyu, Guangzhou; at noon on the 15th, there was hail in the urban area of ​​Shaoguan; hail weather occurred in parts of the cities of Meizhou, Huizhou, Dongguan, Zhanjiang, and Maoming. On the 17th, hail occurred in several towns in Dongguan; on the 18th, hail appeared in parts of Lianjiang, Wuchuan, and Luoding. On the 19th, Shunde Chencun suddenly dropped hail.
Netizens have uploaded pictures of hail photos and complained about the various annoyances.
Why is hail so frequent?
Wu Zhifang, who has been studying convective weather for many years, introduced that in April, this is the month when strong convective weather occurs frequently, and most of the hailstorms occur between February and May when the cold and warm air meet, and they may also land in strong and lasting thunderstorms in midsummer. But she pointed out: "Compared to the multi-year average, the number of occurrences of hail in April this year is indeed too high."
Why does hail occur so frequently? Wu Zhifang said that the intensity of cold air affecting southern China from March to April has weakened, but the weak cold air still frequently affects southern China. In addition, the tropical system has begun to strengthen the northward lift. Both of them frequently collide in South China, often causing a favorable circulation background. The relatively strong upward movement is the reason for the strong convection weather at this time.
Since the beginning of April this year, the warm and humid air flow has been relatively strong, and the duration of maintenance has been relatively long, while the weak cold air has also become more frequent. The cold and warm air are frequently confrontation over Guangdong, causing strong convective weather to appear frequently.
How to judge the next hail?
According to meteorologists, if the weather is cold in the morning and the humidity is high in the next season, the solar radiation at noon is strong and the air convection is prosperous. It is easy to develop cumulonimbus clouds and hail formation. If you encounter such weather, you need to pay more attention.
Min Yun: "Cool in the morning, break the head in the afternoon," "Morning dew is heavy, and after the ice slams," "Black cloud tail yellow head, hail killed sheep and cattle." However, friends who will not watch the sky should still pay more attention to weather forecasts and warnings.
How long can a strong convective weather forecast be advanced? “In highly recognizable weather, optimistic hailstorms can be forecast 30 minutes ahead of schedule.†And more often, the forecast time is shorter. Due to the difficulty of strong convective weather forecasting, even in the advanced USA in the meteorological field, the average advance time for local severe storm warnings is 18 minutes.
In addition, Wu Zhifang stated that it is not possible to drop two or three kilograms of hail in the sky. It should be after the hail fell to the ground and several hailstones piled together and melted into a mass. However, she also reminded that hail damage is so damaging that if there is strong convective weather such as hail, residents should dodge it in time and they should not go out.
