Since our country is affected by the La Nina climate this year, the temperature this winter will be even colder. Do you believe it?
Because our country is affected by the La Nina climate this year, the temperature this winter will be colder. Do you believe it? Will this winter be an extremely cold winter as many reports say? What will be the weather trend this winter? Please read my reasonable statement. Last year, there were a lot of reports that due to the influence of La Nina weather, the winter was the coldest in the past 60 years. As a result, last year's winter was a mild one. Although La Niña still exists in the Pacific, will this winter result in what some reports say is an extremely cold winter? .
As a condition that causes cold winter, it is of course related to the La Niña weather in the Pacific. However, La Niña is also affected by the surface temperature and humidity, which is the main condition and factor that determines whether winter is cold. If there is only the invasion of cold air and there is not a lot of moisture on the ground, the ground will not freeze or freeze, and it will not cause long-term coldness. After the cold air passes, the temperature on the ground will not freeze. It will rebound quickly and there will be no coldness in winter. Isn't there a folk proverb? "A three-foot freeze does not mean a day's cold." This is the reason why winter is cold or not.
Because most areas of our country are now completely in a drought environment, the lack of moisture in the dry ground soil is the main factor causing the higher surface temperature. The higher surface temperature, in After the cold air arrives, it will only form cold air currents in the air. Since the surface layer lacks moisture and the temperature is high, the cold air currents will not have a cold impact on the surface layer, and no freezing ice will form on the ground surface. There will be no freezing on the surface, and there will be no winter cold. If the surface moisture is sufficient and the humidity is high, when strong cold air arrives, the water on the surface will freeze. Due to the long-term freezing of the ground surface, the ice on the ground surface will appear to be stored in the ground. A layer of ice is the main reason for the cold in winter.
Why were the winters in the 1950s and 1960s very cold? That was because at that time there was sufficient water on the surface of the earth, and water from rivers and ditches was flowing everywhere. After the air arrives, winter will cause long-term freezing, which is the reason why the winters in the 1950s and 1960s were very cold.
I remember very clearly that in 2008, on the first day of October in the lunar calendar, due to the exchange of hot and cold air, it started to rain moderate to heavy rain in our area. As the cold wave intensified, it began to rain. There was a heavy snowfall, which resulted in the formation of ice on the ground surface. As winter had just begun, there should not have been such cold weather, but as a result, many trees in my land were frozen to death. As a result, there was a long period of cold weather in the winter of that year. People will not forget that the roads and railways were closed by snow that year, which caused difficulties in long-distance transportation, right? That year was the real cold winter.
This year our meteorological experts have also overturned the saying that this winter will be a cold winter. This winter will be a winter with frequent exchanges of cold and warm air flows. Cold air will continue to appear and the cold air will pass. In the future, the temperature will rise rapidly and the weather will get warmer, followed by the arrival of cold air. This winter is the weather trend this year.
Because in my sixty years of beekeeping, I keep records of meteorological trends every year, which is used to estimate the temperature trend of the year based on the amount of rainfall in the year. Basically, the reference value is relatively high. Yes, because most areas of our country are currently experiencing dry weather conditions. Even in Henan Province in our Great Plains, many places are now in a semi-arid situation where the surface layer is lacking moisture, so I don’t think this winter will happen. It is a cold winter, but cold air will still appear frequently. This winter will not be completely warm. It will be a weather process of constant exchange of cold and warm. This is the trend of weather changes this winter.
