Because our country is influenced by La Nina climate this year, the temperature will be colder this winter. Can you believe it? Will this year's winter be a very cold winter, as many reports have said? What is the weather trend this winter? Please see my reasonable statement. Last year, it was widely reported that winter was the coldest winter in 60 years because of La Nina weather. As a result, last winter was a warm winter. Although La Nina still exists in the Pacific Ocean, will it cause a very cold winter this winter? .

As a condition that causes cold in winter, it is of course related to La Nina weather in the Pacific Ocean, but La Nina is also affected by ground temperature and humidity, which are the main conditions and factors that cause cold in winter. If there is cold air invasion, the ground does not have a lot of moisture and humidity, and the ground will not freeze and freeze, nor will it cause long-term cold. After the cold air passes, the temperature will rise rapidly, the ground will not freeze and it will not be cold in winter. There is a folk proverb. "Rome wasn't built in a day", which is why winter is cold or not.

Because most parts of our country are in a completely dry environment, the dry surface soil humidity and water shortage are the main factors causing the surface high temperature. After the arrival of cold air flow, it will only form a cold air flow in the air. Because of the lack of water on the surface, the cold air flow will not have a cold effect on the surface, and the surface will not form frozen ice, and there will be no cold in winter. If the ground is full of moisture and humidity, when strong cold air comes, it will make the water on the ground freeze. Due to the long-term freezing of the surface, the freezing of the surface is like a layer of ice stored in the stratum, which is the main reason for the cold in winter.

Why was it so cold in winter in the fifties and sixties? At that time, there was a lot of water on the ground, and there was water everywhere. When the groundwater level is one or two meters above the ground, it will freeze for a long time in winter after the arrival of cold air, which is why it was so cold in winter in the fifties and sixties.

I remember very clearly that in 2008, on the first day of the tenth lunar month, under the influence of the exchange of hot and cold air, it began to rain moderately. With the strengthening of the cold current, heavy snow began to fall, which caused the ground to freeze. Because winter has just begun, there shouldn't be such cold weather. As a result, many trees in our area froze to death. As a result, there was a long cold weather process that winter. People won't forget the difficulty of long-distance transportation caused by heavy snow road closure and railway, will they? That year was a real winter.

This year, our meteorologists also overturned the saying that this winter is a cold winter. This winter will be a winter of frequent exchange of cold and warm air, and cold air will continue to appear. After the cold air passed, the temperature rose rapidly and the weather turned warmer, which was followed by the arrival of cold air. This winter is such a weather trend.

Because I have been beekeeping for 60 years in my life, I record the meteorological trend every year, that is, I infer the temperature trend of this year according to the annual rainfall. Basically, the reference value is still relatively high, because most parts of China, that is, our great plain Henan Province, are now in semi-arid areas, so I don't think there will be a cold winter this winter. However, cold air will still appear frequently, and this year will not be a completely warm winter, but a weather process of constant exchange of cold and warm. This is the changing trend of the weather this winter.
