Ding Xuan explained that since mid-October, the cold air in the north has been weak and has basically had no impact on Hunan, so it has remained sunny with no rain; In recent days, the low-level southwest airflow has strengthened and the warm, low-pressure soil has developed strongly, causing the highest temperature break in history. Extreme value of the same period.
Not just Changsha. On November 18, the temperature was warmer in many parts of Hunan. The reporter learned from the Provincial Meteorological Office that the highest temperature at 54 sites in the province exceeded 30 ° C from 14:00 to 15:00, including Changning 31.4 ° C, Jishou, Xinhuang, Chaling 30.9 ° C and Anhua and Mayang 30.8 ° C.
The temperature has plummeted, down to 18 ℃
“This is the last ‘stubbornness’ before the temperature drops,” said Ding Xuan, affected by the strong cold air, a significant drop in temperature and rain is expected in Changsha from the night of the 18th to the 19th. 24 hours will drop from 10 to 14-14 and the south wind will change. Winds from the north are level 4 to 5, and most areas have moderate, local thunderstorms accompanied by strong convective weather such as thunderstorms, strong winds, and short-term heavy rains. From 20 to 24, cold air was added to the south, and the rainy weather continued, and the temperature gradually dropped to about 10 ° C.
“Today is 30 degrees Celsius and the sun is shining brightly. Is tomorrow the season to cool off?” Many friends muttered, the weather is really strange. “Due to the continued sunny weather in the early stage, the temperature remained high.” Liu Jianke, chief forecaster of the Hunan Meteorological Observatory, explained: “Affected by the combined effects of the low-level jets and convergence of shear and strong cold air, the temperature of Hunan dropped dramatically and the wind rose and appeared strong. convective weather – around the 23rd, the minimum temperature in western and northern Hunan will drop below 6 ° C. ”
In fact, looking at the entire country, many places have already started the winter process. The most extensive and intense meteorological process of rain and snow in the central and eastern regions of China since the beginning of winter this year began on the 17th. The Central Meteorological Observatory has continuously issued warnings for blizzards, heavy rain and strong offshore winds. . Inner Mongolia and Northeast China have ushered in blizzards today, especially In Inner Mongolia, Northeast China and elsewhere, there were heavy snowstorms and strong local snowstorms.
Summer and winter turn into one night. Starting on the night of the 18th, Huna residents should be ready to add clothes. The Provincial Meteorological Observatory predicts that Hunan will usher in a process of strong cooling, strong convection and increased wind, and the temperature will drop “seasonally.” Among them, there were two effects of cold air from 19 to 20 and from 22 to 23, and the wind power in the province increased significantly; under the influence of cold air, the maximum temperature dropped by more than 12 ° C, and the drop in southern Hunan could reach 18 ° C.
The meteorological experts recalled that attention should be paid to preventing geological disasters such as landslides and urban and rural flooding that can be caused by intense local rains in the short term; to avoid low visibility, slippery roads, and thunderstorms that can be caused by rainy weather and adverse effects on transportation and travel safety; Prevent the adverse effects of thunderstorms, gales and north winds on the safety of water transportation, high altitude operations, temporary buildings, etc .; pay attention and prevent continuous rainy weather from the 19th on the harvest of rapeseed, citrus and other fruits, and the adverse effects of strong winds on the agriculture of the facilities. .
Also, since the 19th, the temperature in the province has dropped dramatically and the temperature will remain low in the aftermath, so a good job needs to be done in preventing epidemic diseases and reminding the public to stay warm.
