When did Guangdong start to get cold?

1. After winter, the temperature will drop obviously and the weather will get colder gradually. Everyone should be prepared for the cold. The beginning of winter time on 20 17 is: 2065438+0765438+10.7 (the 19th day of the ninth lunar month). After beginning of winter, when people enter winter, the weather will get cold.

As the saying goes, "On the day of beginning of winter, the water began to freeze, and the ground began to freeze". Although beginning of winter has arrived, it is not winter, but late autumn, so the temperature will not drop too much for the time being. But usually around the solar terms in beginning of winter, there will be alternating cold and warm air. One minute the cold wind blows, the next minute the sun shines, and I feel a little dry. With the strengthening of cold air, the cooling trend accelerates. People are used to the coolness in the north. Since the end of 10, heating has been provided one after another, and people have shelter from the cold. For people in the middle and lower reaches of the Yangtze River in the "Xiaoyangchun" in late autumn, if they encounter strong cold air moving southward rapidly, sometimes the temperature can be close to 8 ~ 10℃ or even more in less than a day. According to meteorological data, after winter, cold air activities began to be frequent. Every time cold air comes, there will be an obvious cooling, strong wind, rain and snow, and then it will clear up and gradually warm up, forming a weather change of "three days cold and four days warm".

2. With the strengthening of cold air, the downward trend of temperature accelerates. The average temperature of people in the middle and lower reaches of the Yangtze River is between 12℃ and 15℃. The rain has stopped in Mao Mao. If you encounter strong cold air and move south quickly, sometimes in less than a day, the temperature can be close to 8- 10℃, or even more. But after all, after the gale, the sun shines, the cold air mass degrades rapidly, and the temperature rises rapidly. The rise of temperature and the accumulation of heat prompted the next round of cold air to bring a strong cooling. When there is no wind on a sunny day, there is always warm and comfortable "Xiaoyangchun" weather, which is not only very pleasant, but also very beneficial to the growth of winter crops. But at this time, the cold air in the north also has a strong force, often invading the south frequently, and sometimes it will form a cold wave weather with strong winds, cooling rain and snow.
