Today (August 25) Around 10:30

Typhoon No. 9 this year "saddle"

Land in Guangdong Electric White Coastal

Typhoon

At 20 o'clock, the "saddle" center is located on the offshore sea surface of Beibu Gulf

It is expected to land in Vietnam tonight

Due to the gradually decreased impact on Guangdong "saddle" on Guangdong

At 21:00, Guangdong adjusted the windshield emergency response to Grade IV

What are the characteristics of this typhoon?

Does it still affect Guangdong?

Xu Yinglong, chief forecaster of the Typhoon and Marine Meteorological Forecast Center of the Central Meteorological Observatory, analyzed that the typhoon "saddle" has two characteristics. One is the fast movement speed. Due to the high subtropical high pressure, the south side is large and the guidance of the air flow is strong. "The movement speed is maintained at 30 to 35 kilometers per hour, while the typhoon movement speed of the South China Sea is only 15 kilometers per hour, and the" saddle "is much higher than this level. Second, the structure is asymmetric. This feature is reflected in the influence of wind and rain. The wind brought by the "saddle" appears on the east side of the direction, while the precipitation is concentrated on the west and south side.

Wang Weiyue, a weather network weather network, said that the heavy rainfall brought by the typhoon "saddle" will mainly appear in the Leizhou Peninsula, Guangdong, northern Hainan Island, and south of Guangxi. , Large pressure gradient, coupled with the influence of the shore wind, the wind is strong.

Because the "saddle" moves faster

The rainfall will not stay in one place for too long

Short the typhoon affecting time

up to now

Since the beginning of this year

Among them, "Saiba", "Magnolia", "saddle"

Three typhoon landing in my country

And all "tie" Guangdong

Why do Typhoon favors "Guangdong Hukou"?

Wang Weiyue said that this year's subtropical high -pressure partially curbed the typhoon generation and the development of the north. Under the influence of the guidance airflow on the south side, the typhoon easily tended to South China. In addition, Guangdong has a long coastline. The chance is even greater.

Although the typhoon gradually stays away

But Guangdong also pays attention to preventing heavy precipitation and the secondary disaster that may cause

It can be seen from the radar map that there is still a storm affected by "saddle" over Guangdong. In the past 3 hours, Dongguan, Zhuhai, Shenzhen, Guangzhou, Huizhou, Shanwei and other regions have a large rain. Dongguan has 86.5 mm 3 hours.

It is expected that on the night of the 25th, there are still heavy rainstorms in western Guangdong and Jiangmen and Jiangmen. There are local heavy rain in the southern part of the Pearl River Delta and the county and counties of Guangdong. During the day, most of Guangdong's wind and rain weakened significantly. There is a strong precipitation in the coastal cities and counties of Guangdong, and geological disasters are lagging behind, and relevant defense work must be continued.

The specific forecast is as follows:

From the day on the 26th, most of the wind and rain in Guangdong have weakened significantly. There are local heavy rain or heavy rain in western Guangdong and Pearl River Delta City and counties.

From the 27th to 29th, most of the cloudy weather in Guangdong was mainly, and there were (thunder) showers.

Except for typhoon landing

The Sanfu Tian of the "Extended Edition" this year is finally over

Today (August 25) officially came out

Looking back on Sanfu this year

You can definitely be described as "hot to crazy"

The Central Meteorological Observatory issued a 35 -day high -temperature warning to break the historical record; 40 ° C in the Sichuan -Chongqing area is standard, the highest temperature is comparable to Turpan; the rare "main flood period of the main flood season" appears in the Yangtze River Basin ...

Finally blew up

Is the hottest period really over?

When will the "rejection"?

According to Shi Yan, a meteorological analyst of China Weather Network, in the next week, under the "pinching" of cold air and typhoons, the subtropical high pressure overall has a trend of eastward and south pressure, and the intensity will also weaken. This also means that the long -lasting high temperature weather process in the south will enter the ending stage.

Specifically, on the 26th, due to the influence of cold air and typhoon "saddle", Guangdong, Guangxi, Anhui, Jiangsu, Shanghai and other places will be successfully "receded", but the high temperatures in Sichuan Basin, Jiangnan and other places are still stubborn. From the 27th, with the eastward retreat of the subtropical high pressure, the high temperature weather in the above areas will also be significantly relieved, and the west of the Sichuan Basin will exit the high temperature. From the 30th to 31st, with the further weakening of the high pressure of the subtropical and the gradual spread of the West China Autumn Rain, the most stubborn high temperature in eastern Sichuan, Chongqing and other places will also be successfully "receded". Essence

How hot is this year?

The maximum temperature of over 300 sites breaks the historical record

How hot is this year? China Weather Network sorted out the highest temperature live data of all national meteorological observation stations across the country during this year, and found that the maximum temperature of more than 300 sites reached a new high since the meteorological record. These sites are mainly concentrated in Sichuan, Chongqing, Zhejiang, Jiangsu, Hubei, Hunan, Jiangxi, Fujian and other places. In addition, there are also some sites in Qinghai and Tibet have the highest temperature in the historical record.

From the perspective of the high temperature daily rankings of the provincial capital -level cities, the top ten clear -ranking color is southern cities. The first place in Fuzhou, 38 days in 40 days exceeded 35 ° C. Hangzhou and Nanchang are tied for the second place, with high temperature days of 37 days. Although the fourth -ranking Chongqing has a high temperature of 34 days, the maximum temperature of 18 days in these 34 days exceeded 40 ° C.
