Typhoon Landfall: Will it weaken immediately after landfall?

什么是Typhoon “Landfall”?
Typhoon Landfall has a clear definition in meteorology. it does not refer to the Typhoon center completely Go to land, but rather to the center of Typhoon (i.e. Wind Eye or near the Max Wind area) Moving within the coastline.
Landfall points are usually the strongest wind force, the most concentrated rainfall, and the most affected area. But this does not mean that only Landfall points are dangerous. Typhoon is a huge weather system, with its peripheral clouds and winds often cover hundreds of km. Therefore, even if your city is not the direct Landfall point, as long as you are at Typhoon Seventh Wind Circle or Tenth Wind Circle, you will still be affected by strong winds and Rainstorms. The "coastal Landfall is expected somewhere" is a prediction made by the weather department based on the Typhoon Moving path and speed, designed to remind the relevant area to be prepared in advance.
Landfall后Typhoon 会立刻减弱吗?
This is a common misconception.Many people think that Typhoon will "leak out" once on the shore, and quickly disappear.In fact, the change after the Typhoon Landfall is a complex process that doesn't immediately stop the destruction.
First, the Typhoon will gradually weaken due to the loss of the ocean’s enormous source of energy (the steam and heat supplied by the warm sea water).At the same time, the rough terrain on land (such as mountains, buildings) will increase the friction, consuming the Typhoon’s momentum.
- 地形影响If Typhoon encounters high mountains, the structure may be rapidly damaged and the wind force rapidly decreases; but if it is in the plains, the Typhoon may maintain a longer Time Intensity.
- 水汽补充If Typhoon Landfall is still exposed to sufficient water vapor, or combined with other weather systems, its rainfall capacity may not fall backwards, even trigger Extreme rainstorms.
- 残余环流Even if the typhoon center's wind force weakens to no longer be known as "Typhoon," its residual low-pressure system can still cause heavy rainfall that lasts for days, triggering secondary disasters such as floods or mountain crashes.
因此, 千万不要因为Typhoon Landfall就掉以轻心. 在官方解除警报之前, 风雨威胁依然存在.
如何应对Landfall前后的风险?
In the face of Typhoon Landfall, scientific defense is key to protecting life and property.Beware of the early warning signals issued by the meteorological department before the arrival of Typhoon.It should be noted that the specific standards for shutdowns, shutdowns, and shutdowns may vary, depending on the notifications issued by the local government and emergency management departments.
建议居民做好以下准备:
- Strengthening the windows.: 检查家中窗户是否牢固, 必要时贴上米字胶带, 清理阳台花盆等易坠落物品.
- Reserve materials: 准备至少3天的饮用水, 方便食品, 常用药品以及手电筒, 充电宝等应急照明Tools.
- Avoid going out.During the Typhoon Landfall, wind force is great, signs, trees are very likely to collapse, be sure to stay in the indoor safe area, away from windshield windows.
