What is the specific situation that the temperature in Urumqi drops by more than 20℃?

On September 24th, the autumn rain continued in Urumqi, Xinjiang, and people who went out walked quickly with umbrellas.

The temperature in the city dropped to 2 to 9 degrees Celsius, while the temperature in the city reached 25.8 degrees Celsius at noon on the 23rd. Affected by the strong cold air in western Siberia, Xinjiang has ushered in the strongest cooling weather since autumn.

On September 13, Urumqi experienced short-term rainy weather, and the temperature dropped significantly. People who go out choose long trousers and even put on cotton-padded clothes to keep out the cold.

Before the cold wave invaded, the weather in Urumqi seemed particularly good. The morning is a sunny scene, and the temperature rises all the way during the day. The highest temperature in the afternoon reached 25.8℃.

Some friends who are prepared for the cold weather in advance put on thick clothes early, but they have to complain a few words at noon. There is no need to get caught in the rain to cool down in such hot weather.

Indeed, on the 23rd, the temperature in Urumqi increased significantly. According to the monitoring of Urumqi Meteorological Observatory, in addition to the highest temperature in the main city, the temperature in Midong District even rose to 28.9℃, and even the highest temperature in Nanshan Xiaoqu reached 20.6℃.
