国庆假期期间,冷空气活跃,南北方气温波动较大,南方降雨范围较大,西南部分地区需防范次生灾害。
中国天气网讯 国庆假期首日(10月1日),冷空气将继续东移南下,南方多地也将加入降温行列,3日起,新一股冷空气又将登场。两股冷空气接连影响下,南北方多地气温将创今年下半年来新低,江南多地也将开启入秋进程。国庆假期前半段,南方降雨范围较大,西南部分地区降雨超长待机,需防范次生灾害。
两股冷空气接连来袭 南北方多地气温将创下半年来新低
昨天,今年下半年来最强冷空气继续影响我国,青海北部、甘肃中东部、宁夏、陕西北部及华北中南部、东北地区东部等地气温下降6至10℃,局地12至16℃。
国庆假期首日,这股冷空气将继续东移南下,黄淮、江淮、江南、华南中北部等地有4至8℃降温,局地10℃左右,同时北方气温则陆续开始回升。
不过,假期期间冷空气活跃,预计10月3日至4日还有一股冷空气接力南下,届时北方气温又会出现波动,陕甘宁、华北北部等部分地区将降温8至10℃,同时多地会伴有4至6级偏北风,阵风7至8级。
冷空气接连来袭,南北方多地气温将创今年下半年来新低。大城市中,今天哈尔滨、长春、郑州、合肥、武汉、杭州等地最高气温都会刷新今年下半年来新低纪录;最低气温也将大面积创新低,武汉、南京等地6日最低气温可能降到10至11℃。
国庆假期期间,南北方多地凉意明显加重,公众需及时添衣防着凉。随着气温的波动下滑,秋季的前沿也可能会向南推进,江南多地在国庆假期期间有望开启入秋进程。
假期前半段南方降雨范围较大 华北等地2日至4日将有雨水叨扰
预计在10月5日前,受到冷暖气流交汇影响,南方降雨范围较大,西南地区等地将持续阴雨天气,江南、华南等地部分地区则可能出现强对流天气。10月2日至4日,随着高空槽东移,华北、东北也会自西向东有一次降水过程。
中央气象台预计,今天,陕西南部、重庆北部和东南部、湖北西部、湖南西部、贵州、云南东部、广西西北部、广东东部和南部、浙江南部、福建等地部分地区有中到大雨,其中,贵州东部和南部、广西西北部、广东东南部和中部、浙江南部、福建西部等地部分地区有暴雨。
明天,河南中南部、安徽北部、湖北中部、湖南北部、贵州中西部、广东南部和东部、福建西部以及内蒙古中部、西藏东南部等地部分地区有中到大雨,其中,贵州北部和中部等地局地有暴雨。
后天,贵州大部、云南东部、重庆东南部、湖南西部和北部、湖北南部和东部、江西北部、安徽中南部、江苏南部、浙江西北部、广西北部、广东北部以及内蒙古中部、辽宁中部、西藏东南部等地部分地区有中到大雨,其中,湖南西部、贵州南部、广西西北部等地局地有暴雨。
国庆假期前半段,南方降雨范围较大,西南部分地区降雨时间较长,需警惕持续降雨可能引发的滑坡、泥石流等次生灾害。受冷空气影响,华北、东北等地也将有雨水叨扰,公众外出需带好雨具,驾车减速慢行,留意出行安全。

During the National Day holiday, most areas across the country have good weather conditions and are suitable for travel. It will be mainly sunny to cloudy in the north, and there will be precipitation in North and Northeast China; it will rain first and then become clear in the south, and the rain will be stronger in the southwest. The meteorological department reminded that urban traffic pressure in Guangdong, Zhejiang, Jiangsu, Sichuan, Hunan and other places will be severe. There will be heavy to heavy rains in Fujian, Hunan, Chongqing, Guizhou and other places, and some highways will be slippery and prone to water accumulation. The two waves of cold air relay influence, the coolness in the north becomes more intense, and the heat in the south subsides. In the second half of the Yangtze River, the temperature drops to about 15℃ in the morning and evening.

Wu Derong, an adjunct associate professor at the Department of Atmospheric Science at Central University, pointed out that it will turn to rain in the northern and eastern half of the country from tomorrow to next Sunday, and it will become cooler and the temperature will drop significantly in northern Taiwan next Monday and Tuesday; Light Typhoon Colorful Cloud No. 26 formed over the sea northeast of Guam early this morning and is expected to develop into a large typhoon and head toward the sea southeast of Japan and will not invade Taiwan.

Jia Xingxing, director of Taiwan Integrated Disaster Prevention Engineering Technology Consulting Company, said that starting from tomorrow, there will be a two-stage cooling, especially in the second wave of low temperatures in the open areas in the north, which will drop to around 18 degrees. The northeast monsoon has been reported, and there will be rainfall on the north coast, northeastern corner, and Yilan. Typhoon Caiyun has formed in the early hours of this morning, and a cross-border hurricane NOLO will also move into the central Pacific.

Typhoon No. 26 "Caiyun" was generated on the 1st. It is expected to develop into a strong and wide-circulation system. However, it will not directly affect Taiwan as it moves northward. Instead, it will indirectly promote the northeast monsoon that will last for a long time near Taiwan next week. The northern and eastern half will be significantly cooler. Rainfall will be concentrated on the north coast, the northeastern corner, Yilan and other places. The daytime high temperature in Taipei after next Monday is expected to remain at 25-30 degrees, and the nighttime low temperature will be 20-25 degrees.

The Central Meteorological Administration predicts that the arrival of the northeast monsoon originally scheduled for October 1 will be postponed by one day, and rain will turn to the north and northeast from Friday. Wang Pinxiang, a forecaster from the Meteorological Administration, said that during the northeast monsoon, the temperature will drop below 30 degrees, about 27 to 28 degrees during the day, and about 24 degrees at night. He also predicted that there will still be some short-lived showers on the north coast of Keelung, the eastern half and the Hengchun Peninsula on Saturday and Sunday.

Tropical depression TD30 is located in the northeast and east of Guam. It is expected to intensify into Typhoon "Caiyun", the No. 27 internationally numbered typhoon, which can reach the intensity of a severe typhoon and move northward. However, it is not expected to directly affect Taiwan, and the probability of affecting the Japanese mainland is not high. Whether the external circulation will affect Kantō and Tohoku of Japan still needs to be observed in the later path.
