On July 1st, the date of the Dog Days is determined. Will it be very hot during this year’s Dog Days?
It will definitely be very hot. The hot weather in the dog days cannot be ignored, especially since it spans the two solar terms of Xiaoshu and Sushu. Its humid and sultry characteristics prompted the ancients to have to prescribe appropriate medicine to comply with the laws of the solar terms. And life. Facing rising temperatures, many health problems arise one after another. Preventing heat and humidity was a top priority for the ancients. Are the dog days of summer hot this year?
This year’s Dog Days begin on July 16 of the Gregorian calendar, which is June 18 of the lunar calendar. According to the ancients, the dog days of this year are the "mother's dog days". What is Mu Fu? Female volts are compared to male volts. Every year, there are male and female days in the dog days. According to the time of the lunar calendar, the male day corresponds to "yang", which is an odd number; and the female day corresponds to "yin", which is an even number. From this point of view, this year's dog days of summer are called "mother's days".
Even if the temperature is not high in the dog days of summer, because the surface temperature has reached saturation, the temperature difference between day and night is small, and there is no wind at this time, it will still be very hot, but it will be cooler than in previous years. Everyone still needs to be prepared to prevent heatstroke and drink some mung bean soup from time to time.
The weather is not hot and the grain is not harvested. If the dog days are not hot, then the food harvest after autumn will not be good. Because crops need sunlight to grow. Take corn as an example. If there is enough sunshine, one section of corn can grow in three days. Today's corn has just emerged. It needs sunlight and rain during the seedling stage. If you apply some fertilizer at this time, the corn will grow upward in a hurry.
If the weather turns cooler, it means there will be more cloudy days in the dog days, or there will be more rainy days, which will reduce the number of sunny days. More rain will easily cause waterlogging, dead trees, and ultimately harvest. production will be reduced. It seems that the temperature needs of crops and humans are very different.
Generally speaking, for areas in the Yangtze River Basin, if the average temperature in July is below 30℃, the autumn rainfall will be less than 95mm; if the average temperature in July is above 30℃, the autumn rainfall will be less than 95mm. Will be higher than 95mm.
From this point of view, there are advantages and disadvantages, and everything has its own rules. People crave the coolness of the dog days of summer, but crops need to rely on the normal operation of the weather to ensure harvests. If there is a big contrast in the weather, some unexpected conditions may occur this year, so you still have to follow the laws of nature.
