China News Service, Zhengzhou, October 2 (Reporter Han Zhangyun) On October 2, the Henan Provincial Meteorological Observatory issued a forecast. From the afternoon of the 3rd to the 7th, the temperature in the province will "dive", and the temperature drop in some areas can reach more than 24 ℃.
This round of precipitation is beneficial to alleviating the drought, but it is still necessary to pay attention to the adverse effects, and pay attention to preventing cold and warmth, wind and rain.
According to the monitoring and analysis of the latest meteorological data, the front of the strong cold air in the north has entered Inner Mongolia, and will continue to move eastward and southward in the future.
The Henan Provincial Meteorological Observatory predicts that the cold air will begin to enter Henan Province on the afternoon of the 3rd.
Affected by it, from the afternoon of the 3rd to the 7th, the temperature in Henan Province dropped significantly from north to south, the drop in the north could reach 12-15°C, the drop in the south of the Yellow River reached more than 18°C, and the temperature drop in some areas could reach more than 24°C.
With the strong cold air going south, there will be strong winds and precipitation in Henan.
The Henan Provincial Meteorological Observatory predicts that from the afternoon of the 3rd to the 4th, the northerly wind in the province will be around level 5, and the gust will be level 6 to 7.
From the afternoon of the 3rd to the 7th, there were light to moderate rains in most parts of the province, heavy rains in the west and south, and local heavy rains accompanied by strong convective weather such as short-term heavy precipitation, thunderstorms and strong winds.
On the 5th, sleet may occur locally in high-altitude mountainous areas.
Two days before the National Day holiday, due to the influence of the subtropical high, Henan showed a temperature distribution of "ice and fire".
Northern Henan is located on the edge of the subtropical high pressure, and there is precipitation. Southern Henan and southeast Henan are controlled by the subtropical high pressure, with high temperature and high humidity. The highest temperature in Zhumadian, Xinyang, eastern Nanyang, and southern Zhoukou has broken the historical extreme value for the same period since meteorological records were recorded.
This strong cold air process will cause a "big plunge" in temperature. The meteorological department recommends preventing the impact of strong cooling, strong wind and precipitation on transportation, tourism, travel, production and life, and pay attention to cold protection, wind protection and rain protection.
The western mountainous areas need to guard against secondary and derivative disasters such as flash floods and geological disasters that may be caused by short-term heavy precipitation.
At the same time, this round of precipitation is beneficial to alleviating drought, increasing moisture content, and storing water in reservoirs, but strong cooling, strong winds, precipitation and other weather.
The meteorological department reminds all localities and departments to pay close attention to the latest weather forecasts, meteorological disaster warning signals and meteorological risk warnings issued by local meteorological stations.
