Why is there no typhoon in Rizhao?

The source of typhoon refers to the sea area where typhoons often occur. Global typhoons mainly occur in 8 sea areas. In the northern hemisphere, there are five sea areas: the western and eastern North Pacific, the western North Atlantic, the Bay of Bengal and the Arabian Sea, while in the southern hemisphere, there are three sea areas: the western South Pacific, the western and eastern South Indian Ocean. From the regional distribution map of the number of typhoons and their percentage in the total number of typhoons in the world, it can be seen that there are 62 typhoons on average every year in the world, and there are many more typhoons in the western ocean than in the eastern ocean. Among them, the northwest Pacific is the most (accounting for more than 36%), while typhoons have not been found in the South Atlantic and Southeast Pacific. Typhoon sources in the northwest Pacific are divided into three relatively concentrated areas: the ocean east of the Philippines, the ocean near Guam and the central South China Sea. The typhoon formed in the South China Sea has a great influence on the south of China. Most typhoons occur at 5 ~ 20 latitudes, especially at 10 ~ 20, with an incidence rate of 65%. However, only 65,438+03% typhoons occur at higher latitudes outside 20, and there are few typhoons within 5 near the equator, but there are occasional typhoons. For example, the Fujian Meteorological Observatory found that there were three typhoons in the northwest Pacific Ocean south of 5° n in recent two years. According to the analysis of satellite data in recent ten years, the disturbed clouds that developed into typhoons could be found a few days ago, so the initial position of the disturbance was actually eastward than that previously found. For example, in the North Atlantic, it used to be thought that most of the initial disturbances that developed into typhoons originated in the middle of the ocean, but now some people think that two-thirds of typhoon disturbances originate from the African continent every year according to cloud image analysis. These disturbances usually appear in the form of inverted V-shaped or vortex clouds. They moved westward along the easterly airflow and developed into typhoons when they reached the central North Atlantic and the Caribbean. The initial disturbance position of typhoons in the northwest Pacific and South China Sea is also a little easterly than previously found.

The size and dimension of Shandong Peninsula determine that Rizhao area is not affected by typhoon.
