[Abstract] This year's No.7 super typhoon "Jerahua" was centered at 8 o'clock yesterday at 15.8 degrees north latitude and 127.7 degrees east longitude, which is about 980 kilometers southeast of Taiwan Province Province, and the maximum wind force near the center exceeded1.

Although autumn is getting stronger, "Jerahua" is getting stronger and stronger. Yesterday, it surpassed Bus No.3 to become the strongest typhoon so far this year. This year's No.7 super typhoon "Jerahua" was centered at 8 o'clock yesterday at 15.8 degrees north latitude and 127.7 degrees east longitude, which is about 980 kilometers southeast of Taiwan Province Province. The maximum wind force near the center exceeds 17 (62 m/s), and the radius of the 7-level wind circle is 3000. The wind force of "Jielahua" has reached 17. The Provincial Meteorological Observatory predicts that "Jielahua" will move to the northwest at a speed of about15km per hour, and gradually approach the southeast coast of Taiwan Province Province. Influenced by the peripheral circulation of "Jielahua", on the 27th, the northeast wind of Taiwan Province shallow fishing ground and Minnan fishing ground gradually increased to 8 ~10; On 28-29, the northerly winds along the coast of the whole province were 9~ 10, and the winds in the Taiwan Province Strait could reach10 ~1. From 28th to 29th, there were showers in the coastal areas of our province and moderate to heavy rain in some areas. The cold air has started to go south frequently, but the typhoon is noisy again. At 20: 00 on the 24th, typhoon 18 was generated in the northwest Pacific. At 8 o'clock yesterday, the center was located at 22. 1 degree north latitude and 0/38.7 degree east longitude, and the maximum wind force near the center was 8 (18m/s). It is predicted that "Ayouni" will move to the north in the future, which will have no impact on our province. The existence of two typhoons at sea will make the path of typhoons more complicated. It is understood that the sustained wind speed of "Jielahua" near the center for 2 minutes yesterday reached 65 m/s, above 17, which was the strongest typhoon this year. According to the analysis of the Provincial Meteorological Observatory, "Jielahua" has a strong intensity and its influence is equivalent to that of cold air. There is a strong wind in the coastal areas of the province, so the ships operating and sailing in the relevant sea areas are reminded to prepare for defense in advance. Typhoon in autumn is also very strong, which can not be ignored. Many people think that the temperature will gradually decrease in autumn, and the intensity of typhoons will not be as good as that in summer. However, meteorologists have analyzed that although not every autumn typhoon is strong, strong typhoons often appear in autumn. Typhoon Sanba, the first autumn this year, became a super typhoon at that time. The sustained development of Jielahua defeated Sanba yesterday and became the strongest typhoon this year. This year, * * * has generated four super typhoons, accounting for half of the super typhoons generated since mid-September, and the intensity of typhoons in autumn can be seen. It is understood that from September to June and autumn 10, an average of 2.4 super typhoons are generated every year, accounting for about 48% of the total number of super typhoons generated in the whole year. So, why are typhoons often stronger in autumn? According to the analysis of meteorologists, this is because the sun moves directly to the area near the equator in autumn, which makes the sea surface temperature of tropical oceans higher, and the sea surface temperature after the typhoon is conducive to its strength.
