In the recent 30 years (1988-2018) typhoon intensity ranking, Yutu and a number of typhoons ranked third, only in 2013, the 30th typhoon Haiyan and 2016, the 14th typhoon Moranti.
The Central Meteorological Observatory predicted that the typhoon Jade Rabbit will continue to move westward at a speed of 15 to 20 kilometers per hour, gradually approaching the eastern Philippines, with a slight decrease in intensity. It may cross the northern part of Luzon Island in the Philippines and enter the eastern South China Sea during the daytime of 31 March, and the intensity will continue to weaken. There are still some uncertainties about the late route of the Jade Rabbit, which will slow down after entering the eastern part of the South China Sea and probably disappear in the northeastern part of the South China Sea due to the influence of sea temperature and other factors. Gao Shuanzhu, chief forecaster of the China Meteorological Administrations typhoon and marine meteorology Prediction Center, said.
The number of typhoons produced in August, September, July and October decreases in turn, and the number of autumn typhoons produced in October is generally about 4, according to the high-tethered column. Compared with typhoons in summer, autumn typhoons have three characteristics: the path is southward, the intensity is strong and the losses are more serious. In history, many typhoons have brought heavy impacts to our country. For example, the 2005 typhoon Dawei landed on the coast of Wanning, Hainan in the early morning of September 26, causing severe damage to local agricultural production.

The reason why autumn is prone to super strong typhoons or strong typhoons is related to the warm sea temperature. From the summer to the autumn, the sun moves from north to south, causing the sea surface temperature to be warmer. This is conducive to the accumulation of more heat by the ocean, and accordingly, more energy is provided to typhoons. According to the historical data of typhoons in the Northwest Pacific and South China Sea, 787 autumn typhoons were generated from 1949 to 2017, of which 222 were super typhoons, accounting for 28.2%; during this period, the proportion of super typhoons in summer was 16.5%.
It is expected that during the night of October 28 to 30, under the combined influence of cold air and typhoon Yutu, strong winds of magnitude 7-8 and gusts of magnitude 9-10 will occur in the Taiwan Strait, the East China Sea, the Bashi Strait, the northeastern South China Sea and the central and Eastern seas. In the Bashi Strait, the northeastern South China Sea and the eastern and central parts of the sea, the wind can reach 9-12, gust 13-14. Strong winds will adversely affect ships, offshore platforms, fisheries and tourism in these areas, and precautions should be taken in advance.
