严格来说, 冬天是有可能出现Typhoon 的, 但这种情况非常罕见. 根据China气象局的热带气旋等级国家标准, Typhoon 本质上是 formed at 热带或副热带洋面上的强烈气旋性涡旋. 只要海温, 大气环境等条件满足, 理论上任何月份都可能 formedTyphoon . 然而, 冬季由 at 太阳辐射减弱, 海洋表面Temperature降低, 难以 provides typhoon formed所需的巨大热能和水汽, 因此冬季Typhoon 不仅数量极少, intensity 通常也较弱.
为什么冬季Typhoon 很难“上岸”?
The reason why winter typhoon is very few landfall in China, mainly limited by the double atmospheric circulation and geographical position. first, the winter dominates our country is the strong cold high-pressure system, cold air under the S will form a solid "barrier", will block the tropical cyclone in the low latitude waters. second, guide typhoon Moving's main flow - sub-tropical high-pressure, in the winter positionS and weakening power, leading to typhoon track tend toward SE, away from the mainland coastline.
此外, 冬季高空风切变较大, 这会破坏Typhoon 的结构, 使其难以维持Intensity或 toward 高纬度N上. 因此, 即便有Typhoon formed, 它们大多会在海上转 toward 或消散, 真正能跨越重重阻碍Landfall我国的概率极低. 历史上仅有极少数特例 (如1974年的Typhoon Irma) 在冬季影响过华Scoastal , 但这属 at 极小概率事件.
冬季仍需保持警惕吗?
Although the likelihood of a typhoon landfall in the winter is extremely low, this does not mean that we can fall completely at ease of mind. for residents of at Scoastal area, understanding the following common sense is still important:
- 关注异常天气Even without the Typhoon Landfall, the winter cold air combined with the remaining tropical clouds can result in continuous heavy rains or strong winds.
- 预警信号识别If the meteorological department issues a Typhoon early warning, it should be considered a potential risk regardless of the season.Please note that locally shut down at Typhoon early warning corresponds to shutdown, shutdown provisions may vary, depending on the local government announcement.
- 防范次生灾害If the soil water content is saturated due to the previous period of rainfall, even if the wind force is small, it can also cause geological disasters such as slopes, pay attention to local geo-meteorological risk tips.
科学防灾, 从容应对
In the face of Typhoon, the best defense is knowing in advance and scientific preparation.It is recommended that you develop the habit of regularly viewing weather information, especially after the end of the typhoon high season, and do not immediately cut your attention from the weather dynamics.Al typhoon in winter is rare, but in the context of climate change, the laws of extreme weather events are undergoing subtle changes,ining moderate sensitivity is a responsibility to yourself and your family.
Permanent emergency package in the home, including headlamps, drinking water, common medicines and other items, ensuring that the basic life needs can beined in emergencies. at the same time, cleaning the balcony pool, strengthening the door window and other daily wind measures, should not only be limited to the Typhoon season, but should become the normal life for coastal residents.
