What does it mean when it rains on a hot day?
If it rains heavily on a hot summer day and the water fills the lotus pond, it will rain frequently throughout the autumn and cause disasters during the plum rains.
And this rainy weather will last for a long time until frost. Therefore, if it rains on the day of Chufu, it is a bad omen. The subsequent weather will continue to rain, and crop yields will be reduced resulting in no harvest. Therefore, in order to prevent rain disasters, everyone must arrange the drainage of crops in advance to minimize the impact of rainy days.
There is a saying that goes, "When the thunder breaks out and people sing, the drizzle will continue until autumn." This means that there will be a lot of rainy weather in autumn. This means that if there is thunder and rain on a dog day, then the entire autumn will be covered with rainy days, with frequent rain and little sunshine.
Generally, thunderstorms are more frequent around the summer solstice, but after the Beginning of Autumn, such weather becomes rare. When the weather comes out, it will basically only rain but not thunder.
Weather on a hot day:
After the hot weather, the temperature in most parts of the south is usually below 30 degrees. The summer heat in South China is still basically controlled by the summer monsoon, so the maximum temperature in western South China often exceeds 30°C and in eastern South China exceeds 35°C.
Especially in the low-altitude areas along the Yangtze River, in years when drought continues, the lingering power of the "autumn tiger" is even more felt. In the south, autumn always feels belated. The reason for the formation of autumn tiger is that the western Pacific subtropical high pressure that controls our country gradually moves southward in autumn, but then moves northward. Under the control of this high pressure, it is sunny and cloudy, with strong insolation and high temperature. pick up.
The period of tiger control in autumn varies from half a month to two months each year. Sometimes the autumn tiger comes and goes, goes and then comes back. Therefore, it is not certain how long it will remain hot after coming out of the ambush, and it must be based on the performance of Qiuhuhu. Mostly at the end of August or early September, the temperature will start to slowly cool down.
