The last cold air is not over yet, and the latter cold air will come one after another. Affected by it, the north will once again usher in a clear wind and cool weather after a brief warming, while the southern region will continue to cool down.
Today, the south continues to rain, and the new cold air is coming again.
Yesterday (7th), affected by cold air, there was a northerly wind of 4~6 in the northern region, and the temperature dropped significantly. According to the actual data at 05 o'clock today, compared with the previous day, most of Jilin, most of Liaoning, Heilongjiang The temperature drop in the central and eastern regions reached 4~8°C, and the local landfall decreased by more than 10°C. In the provincial-level cities, both Harbin and Changchun fell by 6°C.
Small to moderate rains or showers occurred in the eastern part of China's southwestern region, Jiangnan, and southern China. With the rain, the above-mentioned areas generally cooled by 2-6 °C, and the local area dropped by 8 °C.
Today, the north of the Yangtze River is in a cold air interval. The temperature in most areas will rise 4 to 8 °C for a short time, and the range of the highest temperature of 15 °C or above will increase compared with the 7th. In the south of the Yangtze River, South China, and Southwest China, it will still be plagued by rainy weather. In the south and south of the Yangtze River, north-central South China, western Guizhou, and eastern Yunnan, there will still be 2~6 °C cooling.
The previous cold air has not stopped, and a new cold air will hit. According to the Central Meteorological Observatory, on the 9th to 11th, the new cold air will affect the north of the Huaihe River in China, with the main winds cooling. On the 9th, most of Inner Mongolia, northern North China, and northeastern China will generally cool down by 2-6 °C, and there will be sand or floating dust in the central and western Inner Mongolia, Hexi in Gansu, and northern Ningxia.
Spring cold air frequent north temperature changes large south continuous rain
Recently, cold air frequently visited China. In response to this phenomenon, Li Xiaoquan, the chief meteorologist of China Weather Network explained: “This is a remarkable feature of spring weather. The cold air moves in the spring is very fast, often one after another. The invasion of our country, but the intensity is not big."
"The new cold air on September 11th will bring different influences to the north and the south. Among them, the temperature in the northern region is fluctuating, the temperature rise and the temperature change are significant, and there are alternating winter and spring feelings, resulting in less precipitation. In Xinjiang, Qinghai, Gansu, Inner Mongolia, and Northeast China, winds and sands will appear. In the south, it is rainy and the temperature is not obvious. The whole will not affect the spring sowing, but it needs to be prevented from being caused by less light. The downside," Li Xiaoquan said.
In addition to the above-mentioned need to pay attention to, Li Xiaoquan also stressed that because the northern region is affected by cold air and dry air, special attention should be paid to forest fire prevention. At the same time, people should also pay attention to various infectious diseases caused by air drying.
After the blizzard in Xinjiang, there is a significant need to prevent snowmelt flooding
From the 3rd to the 4th, there were blizzards in the Yili mountainous area of ​​Xinjiang, the Tianshan mountainous area and the northern part of the Tianshan Mountains. The capital of Urumqi lowered the rare heavy snowfall in the same period of history. Will the cold air cause heavy snowfall again?
According to the Central Meteorological Observatory, the weather in northern Xinjiang will be mainly sunny in the coming week, and the temperature will continue to rise. Among them, from April 8 to 9, the maximum temperature of Altay will rise from 6-8 °C to 14-15 °C, Tacheng will rise from 11 °C to 16 °C, Yining will rise from 18 °C to 21 °C, Ili Valley It will rise from 9 ° C to 13 ° C. On the 13th, the highest temperature in the above areas will rise to 21 °C ~ 23 °C.
The continuous rise of temperature is likely to cause melting and softening of snow in shallow mountain areas, and induce snowmelt floods or avalanches. It is recommended that all parts of northern Xinjiang pay close attention to the warming of the weather, strengthen the monitoring of river water conditions, dyke dangers and mountain snow conditions. Good related disaster prevention and mitigation work.
