Early this morning
Remnant circulation center of Typhoon Anemone No. 11
Came to Guangzhou
(On the morning of the 7th, the center of the "Sea Anemone" remnant circulation was located in Zengcheng)
Although "sea anemone" was discontinued yesterday afternoon
But its residual circulation still hasn't completely disappeared
Even due to its southern side combined with the southwest monsoon
As a result, rainfall has been continuing
(From the night of the 6th to the day of the 7th, the eastern Guangdong region encountered the "train effect", and some places issued a red warning for heavy rain)
The remnants of the "sea anemone" circulation are still pouring water, and red warnings for heavy rain in many places in Guangdong are in effect
At 17:00 on the 6th, the Central Meteorological Observatory stopped numbering this year's No. 11 typhoon "Anemone", but its rainfall stamina cannot be underestimated, and the residual circulation of "Anemone" still brought significant rainfall to Guangdong
According to @Guangdong Weather, most of the province is covered by rain clouds, and as of 10:35, a total of 9 rainstorm warning signals in Guangdong are in effect
@广东天气 It is expected that the precipitation impact of the residual circulation of "sea anemone" will continue to superimpose the influence of monsoon on the 7th and 8th, and there will still be heavy precipitation in Guangdong, which needs to pay attention to preventing secondary disasters such as flash floods, mudslides, landslides, floods of small and medium-sized rivers, and urban and rural waterlogging that may be triggered by heavy rainfall
Huadu weather specific forecast:
From tonight to tomorrow, our area will turn to the south wind area on the east side of the circulation, and the rainfall will be strong, lasting a long time, with a large cumulative rainfall, and the strongest rainfall period is from the night of the 7th to the noon of the 8th (rainfall 80-150 mm, locally more than 200 mm, maximum hourly rain intensity 50-80 mm). Due to the long duration of heavy precipitation and the high accumulation of rainfall, please pay attention to the geological disasters that may be caused by continuous heavy precipitation, waterlogging in low-lying areas, and other secondary derivative disasters.
There was still significant rainfall on the 9th, and weakened on the 10th.
Tonight to tomorrow day, cloudy, heavy rain to heavy rain, temperature 24 ° C to 28 ° C, relative humidity 90% to 98%, blowing a light southeast wind;
On September 9, the sky was cloudy, with moderate thunderstorms and locally heavy rain, and the temperature was 24°C to 29°C;
September 10, cloudy, with showers, temperatures 25°C to 31°C;
September 11, cloudy, temperature 26°C to 33°C;
September 12, cloudy, temperature 27°C to 33°C;
September 13, cloudy, temperature 27°C to 33°C;
On September 14, the sky was cloudy, with thunderstorms and locally heavy rain, and the temperature was 27°C to 32°C.
Beware of the "train effect"!
"Train effect" refers to the accumulation of precipitation generated by multiple convective clouds passing through a certain place in turn, which will lead to heavy rainstorms or even exceptionally heavy rainstorms, just like people standing in front of a passing train, and continuously feeling the huge sound and impulse brought by a section of carriages passing by, and the impact effect is constantly superimposed, resulting in aggravated disasters, prone to secondary disasters such as urban waterlogging, flash floods, and geological disasters.
For example, the heavy precipitation brought by the "sea anemone" to Fujian is not only very alarming, but also the characteristics of short-term convective rainfall during the precipitation process are also very prominent. From 23:00 to 24:00 on September 5, Fuzhou's hourly precipitation exceeded 80 mm for two consecutive hours, and the Fuzhou Academy of Agricultural Sciences even experienced a super precipitation of 148.9 mm in one hour.
"Sea Anemone" has a continuous water vapor supply from the southwest monsoon and the South China Sea monsoon in the south, while there is weak cold air in the high-altitude trough in the north to the south, which forms a cold and warm confrontation in the eastern coastal area of Fujian, so it forms a rainfall "train effect" in the coastal area of Fujian, and continues to experience heavy rainfall.
And typhoons in late September?
Following the "Sea Anemone" this year's No. 13 typhoon "Mandarin Duck" (tropical storm), it formed in the northwest Pacific Ocean on the evening of the 5th, and from the current forecast, there is no impact on the mainland.
At the September press conference held by the China Meteorological Administration on the 5th, Jia Xiaolong, deputy director of the National Climate Center, prompted several points to pay attention to, based on the prediction of climate trends in September
According to reports, September is still a month of heavy rain, thunderstorms, strong winds and other strong convective weather, the north of Northeast China, the east of South China, the southeast of East China, the west of Southwest China, most of Xinjiang and other places precipitation is more than the same period of the year, the above areas need to pay attention to prevent heavy precipitation, strong convection and secondary disasters.
Jia Xiaolong said that it is also necessary to guard against the adverse effects of high temperatures in East China, South China and other places. The number of high temperature (≥35°C) days in southeast China, eastern South China, Xinjiang and other places is higher than that in the same period of the year, and the risk of staged high temperature heat wave is higher. "It is recommended to do a good job in response measures such as heat prevention and cooling, power dispatching, and outdoor construction safety and security, to prevent the harm of high temperature weather to human health, and continue to make preparations for energy supply."
In addition, the South China and southeast coasts should pay attention to preventing the adverse effects of tropical cyclones. Jia Xiaolong said that it is expected that in late September, there may be one tropical cyclone making landfall or significantly affecting the south or southeast coast of the mainland, and it is necessary to pay attention to the possible harm caused by heavy rain, strong winds and storm surges caused by typhoons, be vigilant against the impact of storm surges superimposed on coastal ports, seawalls and related facilities, and do a good job in various countermeasures against Taiwan.
Finally, Xiaobian reminds everyone to take an umbrella to go out, pay attention to safety, and beware of secondary disasters caused by heavy rain
Risk Warning
There was a lot of rainfall in the early stage
And there will be frequent heavy rainfall in the coming days
Care should be taken to prevent heavy rainfall
and the resulting flash floods and geological disasters
