When will the typhoon in Guangzhou end?

Typhoon in Guangzhou usually ends in mid-June at 5438+ 10.

The typhoon season in Guangzhou is from June to 10. In general, typhoons are most active in August and September every year, followed by July, 10. According to statistics, there will be an average of 4 typhoons in June+10 in 5438, with about 0.5 landing typhoons, and the average duration of typhoons is 6 days. In addition, the Mid-Autumn Festival and National Day holidays are longer, so the probability of typhoons entering the public view during the holidays is still relatively high.

Typhoons in Guangdong generally appear after mid-June (the historical average is June 27th) and end in mid-June at 65438+1October (the historical average is September 28th). The best time for the South China Sea and the Western Pacific is May-165438+1October in Guangdong, and September and March in midsummer are the peak periods of typhoon activity.

Strong typhoons are usually accompanied by violent storms, which will cause huge waves and lead to storm surges. As it moves and lands, it will cause great damage to ships at sea and farmland and houses on land. Shantou to the Pearl River Estuary and the east coast of Leizhou Peninsula are the main areas where typhoons land.

Determinants of typhoon track

Typhoon is essentially a deep cyclone formed in tropical and subtropical oceans, and its diameter usually ranges from several hundred kilometers to Qian Qian meters. In the weather system, this diameter is probably in the middle level, and some weather systems wider than it, such as the subtropical high and trough ridge in the westerly belt, can provide airflow to guide it to move-this is the main driving force of typhoon movement.

Among them, the subtropical high, which overlaps with the typhoon active area the most, is the most important system-the typhoon is guided by the airflow at the edge of the subtropical high, moves westward under the influence of the easterly trade winds and other airflow on the south side of the subtropical high, and moves northward at the west edge.

Year after year, the subtropical high moves obviously with the seasonal changes, following the sun to the north in spring and summer, and returning to the south in autumn and winter to avoid the cold wind. Therefore, typhoons generally follow this law-the path is southward in winter and spring, which may affect the Philippines, Vietnam and other places; The north of summer and autumn affects China, Japan, South Korea and other places.

In addition to subtropical high, there are other factors that affect the typhoon path, one of which is the mutual rotation effect when two typhoons coexist and get close together-this phenomenon was first discovered by Dr. Fujiwara of Japan, also known as Fujiwara effect. At this time, two typhoons will move counterclockwise around their center of mass, and the smaller typhoon will be more affected.
