9月8日以来,四川东部、重庆北部、陕西南部、湖北西北部等地阴雨盛行,日照时数偏少。
中国天气网讯 最近,华西一带的朋友们是不是快忘了太阳长什么样了?监测显示,9月8日以来,四川东部、重庆北部、陕西南部、湖北西北部等地阴雨盛行,最近两周平均每天的日照时数不足1小时。难怪网友吐槽:衣服不得干,内裤么得穿。更扎心的是,一直到9月底前,华西地区的雨还要继续下……
明天(9月23日)起,华西地区雨势还将有所增强。特别是四川东部、陕西南部、重庆北部等地,到月底前,上述地区日雨量可达中到大雨,局地暴雨或大暴雨,累计降雨日数可达6至9天。
同时,随着高空槽东移,明天起雨区还会向东扩展,黄淮、江淮的降雨也将增多,25日前后将迎来中到大雨。
目前江苏中北部、安徽西北部、山东等地气象干旱等级达到中旱至重旱,局地特旱,降雨增多将对缓和上述地区的气象干旱十分有利。此外,华北、东北一带未来几天受高空槽频繁东移影响,也会出现过程性降水,多以小到中雨为主。
9月底前华西地区将持续阴雨天气,总体以稳定性降水为主,但持续时间较长,部分地区累计雨量大。公众需警惕持续降雨可能引发的滑坡、泥石流等次生灾害,远离山区等灾害易发区。
华西秋雨持续发力中,但北方的冷空气近期却在“保存实力”。28日之前,影响我国的冷空气总体强度较弱,北方气温虽然在弱冷空气和阴雨影响下有小幅波动,将呈现波动中缓慢下行的趋势,但整体仍接近或偏高于常年同期。
特别是今明两天,华北、黄淮甚至辽宁、内蒙古东南部一些地方最高气温能达到30℃上下,白天还会有点微热的感觉。
而在南方,因为副热带高压强势,江南、华南暑热天气还会持续,最高气温普遍在30℃以上。25日之后高温还可能增多,长沙、南昌、福州都预报了2至3天的高温。夜间最低气温也大多在25℃上下,从早到晚都比较闷热,空调还得继续“连轴转”。
从入秋进程来看,短期内,由于副热带高压偏强、北方冷空气偏弱,全国入秋进程也将总体陷入停滞。目前看,9月28日以后冷空气活跃、实力增强,可能推动北方在国庆节前后全面入秋,秋季前沿也可能向长江沿线推进。不过,预报时效较远,冷空气的具体实力尚不明确,降温幅度待定,大家要保持密切关注哦!

Tropical Depression TD29 is expected to intensify into Typhoon Shuliji today and tomorrow. The current model predictions are divided into two directions: turning north early or continuing westward. If it moves westward and approaches Taiwan, it may have the greatest impact around next Tuesday (29th). Meteorological experts point out that the later development is full of uncertainty.

The Mid-Autumn Festival holiday is approaching. The Meteorological Administration has forecast that the weather will be stable from cloudy to sunny before the weekend, and there is a high chance of enjoying the moon on Mid-Autumn Festival night. Tropical depression TD29 is about 2,000 kilometers away from Taiwan. It is expected to strengthen into a light platform tomorrow and develop into a central Taiwan on Saturday. It may affect the sea surface in eastern Taiwan next Monday and Tuesday, bringing local showers to the north of Taoyuan and Yilan. Pay attention to the accumulation of water during long waves and spring tides.
According to information from the Central Meteorological Observatory, heavy or heavy rains occurred in southern Sichuan, Chongqing and other places yesterday, with local heavy rains. The scope of autumn rain will expand from tomorrow. In the next three days, there will be moderate to heavy rain, local heavy rain or heavy rain in some areas of Shaanxi, Sichuan and other places. We need to be alert to secondary disasters such as landslides and mudslides.

Tropical depression TD29 is expected to intensify into Typhoon No. 25 "Shuliki" as soon as the 23rd, and its intensity will reach above the Central Taiwan level. The current path is divided into two possibilities: turning north or westward to invade Taiwan. If it goes westward, the outer circulation is expected to approach Taiwan next Monday, and the impact will be greatest from Tuesday to Wednesday. Meteorological experts pointed out that the radius of the typhoon's wind circle is about 200 kilometers, which is medium to small. Its future development is still uncertain and it is necessary to continue to observe the forecast trend.

Tropical depression TD29 is expected to intensify into Typhoon No. 25 "Shuliki" on the morning of the 23rd. It is currently located in the sea near Guam. Meteorological experts pointed out that due to the influence of environmental guidance airflow, it will move towards Taiwan in the future. There is a chance that it will be affected by its peripheral circulation from Tuesday to Wednesday next week.

Taiwan is currently affected by northeasterly winds, with localized short-lived showers in the south and mountainous areas. Tropical Disturbance 91W is expected to develop into Typhoon Shuliki No. 25. The second half of the Mid-Autumn Festival holiday (Saturday to Sunday) may affect the sea surface in the southeast of Taiwan. Clouds will increase in the east and the Hengchun Peninsula, and there is a chance of short-lived showers. People should pay attention to the latest developments and adjust their activity arrangements.
