Will it be particularly cold this year?

Since yesterday morning, the circle of friends has started all kinds of "drying?" It's snowing.

1 1 It began to snow, which seems to be much earlier than in previous years. What effect does this phenomenon have on this winter? With questions, the reporter visited experts from the Municipal Meteorological Observatory.

According to lyna, deputy director of the Municipal Meteorological Observatory, the first snowfall began in the early morning of 23rd, mainly switching back and forth between "sleet". The time of pure snow is relatively short, mainly around 8 am, and the time is slightly different in different regions. After that, most areas were sleet, and the underground pure snow time in Xiangzhou and Zaoyang in the north was longer.

The snowfall was mainly affected by the cold air from the south, and the first snow didn't last long. Affected by the eastward fluctuation of high altitude and the cold air on the ground, there will still be light rain in our city today and tomorrow. Citizens still need to pay attention to cold and warmth and carry rain gear when traveling.

Lyna said that the occurrence of snowfall is only the result of this round of cooperation between cold air and water vapor, and does not represent the activity of cold air in the later period.

Meteorologically, the average daily temperature for five consecutive days is lower than 10℃. Even if it enters winter, 1 day is the day of winter.

For example, last year was165438+1October 18, and this year's winter time is165438+1October 2 1, which is actually a little later than in previous years.

As for whether it will be particularly cold this year?

Yu Zhou, a senior engineer of the Municipal Meteorological Observatory, said that since August this year, the central and eastern Pacific Ocean has been in La Nina state, but it is not obvious. After 10 months, La Nina phenomenon has become more obvious. At present, a weak to moderate La Nina event will be formed this winter.

La Nina means "La Nina" in Spanish? A "-"little girl, saint "means the reverse of El Ni? o phenomenon, also known as" anti-El Ni? o "or" cold event ". It refers to the abnormal drop of water temperature in the eastern Pacific near the equator, which is characterized by the obvious cooling of the eastern Pacific and the global climate chaos, and always appears after the El Ni? o phenomenon.
