Recently, the weather has been abnormal in various parts of the mainland, and extreme weather phenomena have frequently appeared, which have aroused widespread concern. From the tornadoes and hail in Guangzhou in the south to the heavy snowfall in Hebei in the north, a variety of extreme weather events have made people wonder: what causes these anomalies to occur?
Extreme weather is frequent: tornadoes, hail and goose feather snow
On April 27, the city of Guangzhou, Guangdong Province, was suddenly hit by a rare tornado and hailstorm. The tornado is EF3 and the hail is even larger, the size of a melon. In the relatively arid north, the northern part of Hebei also ushered in a sudden goose feather snow on the 28th, and the snow depth once reached more than one foot.

The appearance of tornadoes and hail is associated with the convergence of warm and moist air currents with cold and dry air. With the transition of spring and summer, the warm and humid airflow gradually intensifies, and the solar radiation energy also intensifies, resulting in atmospheric instability. When this warm, moist air meets cold, dry air from the west, it triggers strong convective weather, including heavy rain, tornadoes, and hail. Global warming is also exacerbating the instability of the climate system and increasing the frequency and intensity of extreme weather events.

The occurrence of heavy snow in northern Hebei Province is the result of the conflict between cold and warm airflows. Although summer is just around the corner, there is still the possibility of cold air from the north moving south. When cold air meets warm and humid air currents, it can lead to extreme weather such as heavy rain and blizzards, especially when the temperature is low enough to form a soft snow like goose feathers.

The frequency of these extreme weather events reminds us of the severity of climate change. Global warming has made extreme weather events more frequent and intense, which poses great challenges to human society and natural ecosystems.

In the face of these weather changes, we need to strengthen meteorological monitoring and early warning, raise public awareness of climate change, take effective countermeasures, strive to slow down the process of climate change, and protect the ecological environment of the earth's homeland.
