中国天气网讯 今天(10月15日)起至19日,新一股冷空气将自西向东影响我国,局地降温幅度可达8℃以上,北方大部气温将刷新今年下半年来新低,寒意逐渐显现,入冬进程将加快。在冷暖气流交汇下,今天湖南、湖北、江西、安徽部分地区有暴雨;明天开始,北方降水将增多,过程的影响范围、累计降水量或为同期少见。
新一股冷空气来袭 北方寒意显现大部气温将创新低
近期,冷空气频繁影响我国,昨天北京、西宁、沈阳、长春最低气温创今年下半年来新低,黑龙江等地降温明显,像哈尔滨午后气温仅个位数,为立秋后首次出现全天气温不足10℃。
今天开始,新一股冷空气又将影响我国,预计15日至19日,新疆北部、内蒙古、华北、东北地区、黄淮、江淮、江汉、江南西部和北部等地先后降温4至6℃,局地降幅可达8℃以上。
今天最高气温25℃线还位于山西中部、河北中部一带,19日前后将南退至长江沿线。到20日,北方大部最高气温将不足20℃,西北、华北北部、东北地区多地最高气温不足10℃。北方气温将大面积刷新下半年来新低,像呼和浩特、乌鲁木齐、西宁最高气温将在今年下半年首次降至10℃或以下。
最低气温也将陆续下降,北方寒意更加明显。到19日前后,最低气温10℃线会南压至黄淮,0℃线将抵达华北北部、西北地区中部。大城市中,呼和浩特、西宁、银川、乌鲁木齐最低气温将跌至冰点或以下。届时,北方更多地方会进入气象学意义上的冬天。
对江南、华南来说,今天冷空气渗透南下,30℃以上的范围将收缩至江南南部、华南一带。但明天起,副热带高压强势北抬,30℃以上的范围再度北扩,同期少见的暖热将延续。
南方较强降雨持续 北方将迎同期少见强降雨
在冷暖空气交汇下,昨天南方降雨明显增强,实况监测显示,湖南等地部分地区出现大雨或暴雨,益阳局地遭遇大暴雨。
今天,南方降雨持续,强降雨落区将向东转移,预计新疆北疆北部、沿天山地区和南疆西部山区高海拔地区、青海西部和中部等地部分地区有中到大雪或雨夹雪,其中,新疆北疆阿勒泰山区和沿天山地区高海拔地区等地部分地区有暴雪。贵州东北部、湖北南部和东部、湖南中北部、江西北部、安徽西南部等地部分地区有中到大雨,其中,湖北东部、湖南中北部、江西北部、安徽西南部等地部分地区有暴雨。
明天开始,随着副热带高压再度增强,暖湿气流显著加强并北上,同时新一轮冷空气东移南下,长江以北降水增多、增强,北方将迎同期少见强降雨。预计新疆南疆南部山区、青海、甘肃河西、西藏北部和东部等地部分地区有小到中雪或雨夹雪,其中,青海中东部等地部分地区有大雪。内蒙古河套地区、西北地区东部、华北中南部、黄淮、江汉北部、四川盆地东北部等地部分地区有中到大雨,其中,甘肃东部、陕西北部和西南部、河南中部和南部、四川东北部、重庆北部等地部分地区有暴雨。
后天,内蒙古东北部、黑龙江西北部等地部分地区有中到大雪或雨夹雪,局部地区有暴雪或大暴雪。内蒙古东部、东北地区中南部、华北、黄淮、江淮、江汉、江南地区西北部等地部分地区有中到大雨,其中,山东中东部和南部、河南东部、江苏北部、河北东部、辽宁中南部等地部分地区有暴雨或大暴雨。
这轮降水过程的影响范围、累计降水量以及单日降水强度或是同期少见的,降水有利于缓和山东、江苏一带气象干旱,但也要注意降水可能引发的能见度降低、道路湿滑等对交通出行造成的不利影响。

The Central Meteorological Observatory predicts that in the next 10 days, the cumulative precipitation will be 10 to 30 millimeters in the eastern part of Northwest China and central and northern North China, 50 to 80 millimeters in the middle and lower reaches of the Yangtze River, and more than 200 millimeters in some places such as northeastern Sichuan; cold weather The air activity is frequent, and the average temperature in Xinjiang, North China and other places has turned 1 to 2°C lower, and it has been higher in the south of the Yangtze River and in the south of China. There was a significant cooling process on the 15th-18th, 20-21st, and 23-24th, with local rain, snow or sleet.

Precautions need to be taken against disasters such as thunder and lightning, flash floods, mudslides, urban waterlogging, thunderstorms, strong winds, and hail.

Meteorological experts pointed out that due to the influence of radiation cooling, the low temperature in Hsinchu and Guanxi dropped to 16.5 degrees. Today, the temperature difference between day and night is large across Taiwan. The west is sunny and stable, and there are local brief rains on the windward side of the northeast.

Singapore is gathering data on regional haze pollution as it evaluates potential enforcement under its 2014 Transboundary Haze Pollution Act, with PSI readings between 125 and 206 recorded across the island as of 6am local time, and western Singapore showing the highest levels.

Indonesia is facing its worst wildfire season in a decade, with toxic smog spreading to Singapore and Malaysia and air quality reaching dangerous levels. The haze is caused by illegal slash-and-burn farming, partly linked to businesses in Singapore and Malaysia. Indonesian President Prabowo called it "eco-terrorism" and strengthened punishment, but cross-border law enforcement has been hindered and relations with neighboring countries have become tense.
