双Typhoon 真的会“撞车”吗?
In the Northwest Pacific summer season, there are occasional situations where two or more typhoons are active at the same time. Many friends are curious: Will they not collide directly like a car crash? In fact, typhoons rarely have a physical “hard collision”. This is because typhoon is essentially a giant low-pressure cycling system, often up to hundreds of kilometers in diameter. When the two typhoons are close to each other, the air flow and air pressure fields interact complexly, causing each other’s path to deviate, rotate or bond, rather than a simple straight line collision. This phenomenon has a special name in meteorology – the Fujiwhara Effect . Simply put, the two typhoons are more like jumping in a complex “man dance”, affecting each other, eventually dispersing each other
什么是藤原效应?
藤原效应由Japan气象学家藤原咲平在1920年代提出, 指的是两个距离较近的热带气旋围绕两者连线的中心点作逆时针 direction旋转的现象. 你可以把这两个Typhoon 想象成两个在冰面上手拉手旋转的舞者. 具体表现通常有以下几种情况:
- 相互旋转If the two typhoon intensities are equal, they will rotate around the same central point, making the path difficult to predict.
- 一强一弱If the Intensity is suspended, the stronger typhoon will dominate the situation, the weaker typhoon may spin around the stronger, and even be absorbed by the stronger, resulting in the stronger being further enhanced.
- 排斥分离In the context of certain atmospheric circles, both may also reject each other, and vice versa.
This effect greatly increases the difficulty of typhoon trackForecast, because in addition to considering the impact of large-scale environmental air flows, the interference caused by another typhoon must also be calculated.
面对双Typhoon , 我们该如何应对?
Twin Typhoon total holds, weather conditions tend to be more complex and variable. a Typhoon brings storms may be overlayed by another Typhoon's peripheral clouds to zoom in, resulting in rainfall lasting longer Time, wider range.
First, do not just judge by experience when the storm ends. Twin Typhoon may cause the storm to intensify again after the "interval" process, do not go out during the storm temporarily. Second, pay attention to the official issued early warning signals. According to China Meteorological Administration's tropical cyclone level national standards, Typhoon may be divided into Tropical Storm, Severe Tropical Storm, Typhoon , Severe Typhoon and Super Typhoon five levels. When issuing Typhoon yellow and above, recommend reducing outdoor activities; if issuing orange or red early warning, some areas may start classes, stop work measures. Please note that the standards may vary from place to place, according to the local government.
Finally, check whether your home door windows are solid, clean the balcony dirt, reserve the necessary drinking water and food.In complex weather conditions, it is crucial to keep information available.Live Typhoons path is available at TyphoonSays (taifengshuo.com)
