受副热带高压加强与冷空气交汇影响,中国北方迎来大范围强降雨雪及降温天气。
中国天气网讯 今天(10月17日)大范围雨雪过程将进入最强时段,北方将现同期少见的大范围大到暴雨,局地有大暴雨,内蒙古东北部、黑龙江西北部局地有暴雪或大暴雪。降水的同时,北方多地气温也将刷新今年下半年来新低。一直到下周,冷空气频繁影响我国,北方气温持续偏低,江南等地在经历近期的暖热后,21日前后也将出现降温,秋凉显现。
本轮降水过程最强时段到来 北方大范围大到暴雨来袭
随着副热带高压加强,大量水汽沿其边缘输送到我国,在与冷空气交汇后,昨天我国降水范围扩大。实况监测显示,宁夏北部、陕西中部和西南部、山西南部、河南中部和东南部、重庆北部、湖北中西部、云南东南部等地部分地区出现大雨,重庆巫溪、云南红河等局地暴雨或大暴雨;新疆北部、甘肃中西部、青海东部、川西高原北部等地部分地区出现小到中雪或雨夹雪。
今天,本轮降水过程最强时段到来,强降雨范围继续东移并扩大。中央气象台预计,内蒙古中东部、黑龙江西南部、吉林西部、辽宁大部、河北中北部、北京、天津、山西东北部、山东中东部和南部、河南东部和南部、安徽北部、江苏北部、湖北中东部和南部、湖南北部、重庆北部等地部分地区有大到暴雨,其中,山东西南部、辽宁南部局地有大暴雨。新疆北疆北部、甘肃中西部、青海中东部和南部、内蒙古东北部、黑龙江西北部、西藏东部等地部分地区有中到大雪或雨夹雪,其中,内蒙古东北部、黑龙江西北部局地有暴雪。
明天,华北、黄淮大部降雨将结束,东北以及长江中下游沿线仍有明显降水。预计,黑龙江中部和东部、吉林东部、辽宁东部、湖北西南部和东部、湖南西北部、安徽中南部、江苏中南部、重庆、贵州北部等地部分地区有中到大雨,其中,吉林东北部、安徽中部、江苏中南部、湖北东部和西南部等地局地有暴雨。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,局地大暴雪。
后天,河南南部、湖北西南部和东北部、安徽中北部、江苏中北部、重庆东部等地部分地区有中到大雨,其中,江苏中部、湖北西南部等地局地有暴雨。青海北部和南部、甘肃河西、内蒙古中部和东北部、黑龙江西北部、华北北部等地部分地区有小到中雪或雨夹雪。
中国天气网提醒,北方这轮降水过程在影响范围、累计降水量以及单日降水强度上或是同期少见的,内蒙古东北部、黑龙江西北部降雪强度大、持续时间长,公众需防范雨雪天气对交通、农业等造成的不利影响,还需警惕强降雨可能引发的次生灾害。
北方气温将频繁创新低 江南等地下周迎降温
今起三天,较强冷空气继续东移南下,给长江中下游及其以北大部地区带来降温。之后,20日至21日、23日至25日还将有两股冷空气接力影响我国。
在冷空气影响下,今后五天,北方气温将频繁刷新今年下半年来新低。其中,今天北京、太原、天津、石家庄、兰州、银川、济南等地最高气温将掀起创新低浪潮,随后气温有所波动,21日前后将继续下探并大范围创新低。
从最低气温来看,21日前后,0℃线将向南推进至陕西中部、山西南部,西宁、太原、银川等地最低气温将先后跌至冰点或以下。最低气温10℃线也将南压至黄淮,像北京、石家庄后天起最低气温持续低于10℃。
南方在副热带高压控制下,今天30℃以上范围达到近期最广,北界延伸至湖北、安徽南部,气温偏高的格局将延续至下周。21日,江南等地也将出现10℃以上降温,像上海、杭州、长沙等地最高气温或降至20℃上下,秋凉上线。公众需注意气温变化,适时添加衣物。

20日至21日及23日至25日将有两股冷空气影响我国

The Meteorological Administration pointed out that before the 20th, it will be cloudy to sunny in various places, and the high temperature will be 35 degrees. Moderate typhoon Qiangpi will become stronger as soon as tonight and is expected to arrive off the eastern coast of Taiwan on the 22nd. Its subsequent path may turn north or westward through Taiwan, and its movement has attracted much attention.

Jiangsu consumers suspected that it was wild Nostoc after buying it online and called the police. After investigation, the police seized more than 600 grams of wild Nostoc in Ningxia. Experts pointed out that wild Nostoc is actually Nostoc algae, a national first-level protected wild plant. Large-scale mining has seriously damaged the desert ecology, and selling wild Nostoc is suspected of being illegal.

The Singapore-based ASEAN Specialised Meteorological Centre activated Alert Level 3 for the Southern ASEAN region due to ongoing fires in Indonesia causing widespread transboundary haze, which has disrupted daily life across Southeast Asia by closing schools and increasing respiratory illnesses.

Typhoon "Qiangpi" intensified into a moderate typhoon early this morning. The forecast indicates that it will continue to intensify into a strong typhoon in the future. Next Thursday (22nd) will be a key turning point. It needs to be observed whether it turns north or directly attacks Taiwan. Forecaster Zhang Chengchuan of the Meteorological Administration said that the strengthening of the northeast monsoon next week will bring local short-lived showers. Next Friday, the outer circulation of Typhoon Qiangbi will affect the northern and northeastern areas of Taiwan, with showers, and there will also be local short-lived showers in the east and southeast. The actual extent of the impact still depends on the degree of the typhoon's northward turn or its distance from Taiwan. The current pressure at the center of Typhoon Qiangpit is 950 hPa. The center is located at 12.3 degrees north latitude and 148.5 degrees east longitude, that is, on the sea 3120 kilometers southeast of Eluanbi. It moves westward at a speed of 24 rpm and 20 kilometers per hour. The maximum wind speed near the center is 40 meters per second, which is equivalent to Category 13 winds. The radius of Category 7 storm winds is 180 kilometers and the radius of Category 10 storm winds is 80 kilometers.

Meteorology expert "Taiwan Typhoon Forum | Weather Emergency" released an eye-opening photo of Typhoon Qiangpi, pointing out that its core structure is becoming more and more solid and its intensity continues to increase. It is expected to become a strong typhoon tomorrow. Qiangpi intensified into a moderate typhoon at 2 a.m. today, and satellite cloud images showed a small typhoon eye in the center.

Lin De'en, a doctor of atmospheric sciences at National Taiwan University, pointed out that Taiwan will still continue to have high temperatures in mid-October, with high temperatures reaching 32 to 35 degrees in the western half, and may soar above 36 degrees in the mountainous and inland areas of central and southern China. People are reminded to protect themselves from the sun and replenish water. Starting from the 21st, the northeast monsoon will strengthen, and the temperature will drop significantly in some areas. At the same time, pay attention to the development of the mild typhoon "Qiangbi" in the east of Guam.
