It should be the season of high autumn and crisp, and Guangdong actually appeared to return to the south of the skyIn the past two days, the weather has warmed up, and there have been water droplets on the floors and walls in some parts of Guangdong, and clothes are difficult to dry. There are observation stations in the south of Guangzhou that have entered the range of "there is a possibility of returning to the south". The day after tomorrow, there will be weak cold air moving southward, which may help to ease the return to the south.
"Back to the south" is a folk saying, the reason why it is called "back to the south" is because the north wind generally prevails in autumn and winter, and sometimes after the influence of cold air, the warm and humid airflow in the south strengthens to the north, and then the north wind turns to the south wind, and the tide returns, and the folk use "back to the south" to describe this phenomenon. Strictly speaking, "returning to the south of the sky" is not a real weather phenomenon, but more of a phenomenon of condensation of water on the surface of indoor objects by humid air that is common in life.
It is understood that the "return to the south sky" occurs throughout the northeast monsoon period, and occurs most frequently at the end of the period, that is, in February and April. As long as certain conditions are met, it is possible to "return to the south". Generally speaking, there will be a cold air process before the "return to the south", and in addition, there will be a sudden change in the weather, and it will suddenly become warm and humid after a long period of low temperatures.
Guangzhou experienced a cooling on December 6, and recently affected by the convergence of low-level southerly winds, there are more clouds, with occasional light rain and light fog in the morning and evening. All these have created conditions for the emergence of Hui Nantian.
The reporter saw today that there was a meteorological observation station in Panyu District that was once marked yellow, indicating that "there is a possibility of returning to Nantian". The ground temperature at the site is only 0 percent higher than the ** temperature4℃。*Temperature is the temperature at which water vapor in the air turns into dewdrops. Generally speaking, when the temperature of the object is less than or equal to the ** temperature, the water vapor in the air will condense on the surface of the object. Due to the recent high daytime temperatures, it is not so rampant to return to the south around noon. Shaded areas are more likely to appear back to the south than sunny places.
The weather forecast shows that on December 12, there will be weak cold air affecting Guangzhou. After the northerly wind blows, the phenomenon of returning to the south is expected to ease.
