Analysis: Gathering high -temperature and high energy during the day, easy to develop thunderstorms and windy weather

Liang Zhiyan, chief forecaster of Guangzhou Meteorological Observatory, said that the thunderstorm weather was formed by low -level convergence of high -temperature and high -energy gathering meteorological conditions. Liang Zhiyan explained that when a place is more hot during the day, it is easy to cause the atmospheric instability; when the energy accumulates to a certain degree, it is easy to trigger similar thunderstorms.

Liang Zhiyan said that from the actual situation of the weather on September 18, in addition to Guangzhou, Yangjiang, Shenzhen, Shanwei, Zhanjiang and other places in Guangdong Province also appeared in the afternoon of the day. It is not a solitary case in the province of Guangdong.

From September 20th to 21st, Guangzhou may welcome the heavy wind of thunderstorms

It is expected that from September 20th to September 21st, the thunderstorms in the urban area of ​​Guangzhou gradually turn significantly; 9 On the 22nd, thunderstorms affecting the urban area of ​​Guangzhou will weaken.

Liang Zhiyan said that according to the existing meteorological data, it is expected that from September 20th to September 21st, similar to the thunderstorms from September 18th to the early morning of September 19 will appear again in Guangzhou. However, considering factors such as energy accumulation and consumption, if the thunderstorms on September 20 are relatively strong, thunderstorms on September 21 will be relatively weak; if the thunderstorms on September 20 are relatively weak, then September 21, then on September 21st Thunderstorms may be relatively strong. It is recommended that citizens go out to prepare for rainy gear in the near future and notice the latest information released by the meteorological department.

Although thunderstorms or heavy weather may appear again, according to the forecast of the Guangzhou Meteorological Observatory on the evening of September 19, weak and cold air will reduce the highest daily temperature in Guangzhou City, which is expected to drop from 35 ° C on September 20 to September 21st 33 ° C in the day. Although the maximum temperature of the daily daily daily on the weekend may return to about 35 ° C again, a brief cooling and precipitation can slightly alleviate the effects of long -term dry and high temperature weather.
