Is the normal high temperature weather in China caused by the subtropical high in the western Pacific?

According to reports, since the beginning of July, there has been a "large-scale continuous" high temperature weather in China. The Central Meteorological Observatory began to issue a high temperature warning on July 7, and as of July 25, it has issued a warning 19 days. Experts say that the "culprit" of high temperature roasting in the south is the western Pacific subtropical high.

According to the report, according to the climate experts of the National Climate Center, the high temperature in the north in the early stage was caused by the high pressure in the northern continent. At present, the extreme high temperature in the south is due to the strong subtropical high in the south, which dominates the middle and lower reaches of the Yangtze River. Under the control of this huge heating mass, the airflow sinks, the temperature is high, and there is little rain; This weather situation also makes the typhoon path southward, which is not conducive to alleviating the high temperature.

The deep-rooted western Pacific subtropical high is the "culprit" that causes large-scale high temperature weather in South China. In the area controlled by subtropical high, downdraft prevails, which is not conducive to the formation of clouds, and it is often sunny and partly cloudy, which is conducive to the continuous heating of the near-surface atmosphere by solar radiation.

Experts say that the air will heat up with the sinking process, which also makes the subtropical high pressure control area prone to high temperature weather to some extent. Because the subtropical high has been relatively strong, the temperature in many places in the south has hit record highs, and everyone needs to pay attention. Take preventive measures.
