Starting from the winter solstice, the "Nine Cold Days" begins. "1929 does not take action, 3949 walks on ice" is obviously a symbol of cold weather in the year, but this time, we have a different feeling -
Starting from January 6, Chengdu's average The maximum temperature has been above 14℃, and it reached 18.4℃ at 16:00 on the 9th, which is the highest temperature in the new year! This weekend continues to be cloudy and sunny in the previous period. As of 16:00 today, the average maximum temperature is 16℃, which is 2.8℃ higher than yesterday. It is really ridiculously warm. Why is
so warm? Yang Rong, chief forecaster of the Chengdu Meteorological Observatory, analyzed that since January, the main path of cold air has been eastward. Chengdu is mainly affected by the return of weak cold air, resulting in weak precipitation and insignificant cooling.
After being warm for so long, the slack cold air is finally starting to take effect! The Chengdu Meteorological Observatory predicts that cloudy weather will continue in the next three days, with scattered light rain or sporadic light rain falling from time to time in the central and western regions. The daily maximum temperature will drop from 15℃ in the previous period to 11℃ on the 17th, and the daily minimum temperature will be around 8℃. In addition, there will be a cooling weather process around January 28, with the highest temperature dropping to only 7°C and the lowest temperature hovering around 2 to 3°C.
Under the double pressure of cold air + rain, the familiar dampness and coldness are coming back again. Wear rain gear when going out to prevent cold and keep warm.
Looking back on the weather in 2023
Looking back on 2023, when summer comes early and winter comes late, what moment makes a deep impression on you among the weather this year? Today, Cheng Qingyan, a senior engineer at the Municipal Meteorological Observatory, took stock of the top ten weather and climate events in Chengdu.
January precipitation was abnormally low

Extreme winds occurred on "3·11"
On the evening of March 11, 2023, gusty winds occurred in most places in Chengdu, with the maximum wind speed reaching 24.8 meters/second (level 10). What is the concept of level 10 wind? Generally, wind strength is divided into 13 levels, with the minimum being level 0 and the maximum being level 12. Winds of level 10 are called "squally winds" and can "uproot trees" on land.
In early April, the temperature was abnormally high and exceeded the extreme value.
On April 17, 2023, the highest temperature in Chengdu reached an average of 33.8℃, which was nearly 10℃ higher than the same period in normal years.

On the evening of July 27, 2023, the rainbow and flowing clouds were like a dream.
On the evening of July 27, 2023, as the continuous heavy rainfall gradually stopped, under the afterglow of the setting sun, the sky above Chengdu was filled with clouds and mist, the sea of clouds flowed, and a dazzling rainbow appeared on the horizon.
