What is the conclusion of warm winter?

The concept of warm winter has a strict scientific definition. Whether it is a warm winter depends on whether the national average temperature in the whole winter is higher than the normal value. So when the temperature is high (relatively warm) at a certain time in winter, it is said to be warm winter, and when the temperature is low (relatively cold) at another time, it is said to be cold.

In winter, there will be jokes that winter is both warm and cold.

Xinhua Shanghai Channel 65438+1October 7th News: The temperature below zero is leaving us. Yesterday, the highest temperature in Shencheng reached 15.6℃, which made people feel the long-lost warmth. The reporter learned yesterday that the temperature in this city will continue to climb this week. Therefore, in the next few days, citizens can seize the opportunity to enjoy these warm days in winter.

If the cold air doesn't come, the cold will lose its supporters behind the scenes. Yesterday during the day, controlled by high pressure, with the help of warm sun and southeast wind, the temperature in Shencheng soared. Except that the lowest temperatures in Fengxian and Jinshan are -0.8℃ and -0.3℃ respectively, the lowest temperatures in other areas all exceed 0℃, and the highest temperature is higher than 15℃. As a result, yesterday became the warmest day this winter since last year 12. At the same time, the relative humidity in this city was also very suitable yesterday, and it was basically maintained at around 60% during the day, with a high sense of body.

According to the latest meteorological data, the temperature will continue to climb this week. It is predicted that under the control of the high-pressure wedge, the whole city will be cloudy today, with the temperature of 6℃- 14℃, the highest temperature on Wednesday 15℃ and the lowest temperature on Thursday 1 1℃.

Temperature and date

Does this mean that this winter will be a "warm winter"? Meteorologists said that it is still difficult to draw this conclusion. On the one hand, this year's cold air strength is actually not weak. The obvious wave of cooling around New Year's Day is a good example. As for the temperature rise these days, it is because the main body of cold air activity is northward. If their activities move south to this city, there will be obvious cooling weather in this city. On the other hand, the so-called warm winter, as far as this city is concerned, means that during the three-month period from 65438+February of one year to February of the following year, the average temperature is 1℃ higher than normal, and only one third of this year's winter has passed, so it is difficult to assert that the next temperature will make this city usher in a warm winter again.

However, meteorologists also pointed out that for citizens, the warm winter in the meteorological sense has little guiding significance for daily life. It is important that citizens should take timely measures according to the weather changes in order to spend the winter safely.
