What is Wind Circle?
When viewing Typhoon early warning or road maps, you can often see the two concepts of "seventh-level wind circle" and "ten-level wind circle".Simply put, they represent the range of influence of the wind force of different intensities outside of Typhoon. According to the national standard of the "tropical cyclone level" issued by the China Meteorological Administration, Typhoon is a huge air spiral, its internal wind force distribution is uneven: the strongest wind force near the center, the weaker the outside wind force.
The meteorological department typically divides these circles by the maximum average wind speed near the center of the bottom. Seven levels of wind.refers to the regional limit where wind speed reaches or exceeds 13.9 m/s (i.e. wind force level 7 and above); andThe 10th wind.You can imagine a typhoon as a rotating spiral, the 10th wind circle is close to the center, the destructive "core destruction zone", while the 7th wind circle is wider, enough for people to stand unstable "external impact zone".
What are the risks of different winds?
Understanding the size of these two windshields can help us more intuitively assess the degree of danger:
- Level 7 Wind Circle (Great Wind Warning Zone) : 当你的PositionGo to Seven levels of wind., 意味着你会感受到明显的强风. 此时, 树枝可能被折断, 广告牌晃动, 行人迎风行走困难, 海上船只航行受到显著影响. 这是Typhoon 开始产生实质性影响的标志, 也是我们需要开始做防风准备的时刻.
- Level 10 Wind Circle (Seriously Damaged Zone) : 一旦Go to The 10th wind., wind force将具有极强的破坏性. 大树可能被连根拔起, 简易建筑可能倒塌, 玻璃窗面临破碎风险, 户外行动极度危险甚至不可能. 对 at 大多数居民而言, 身处十级风圈内意味着必须留在坚固的室内, 严禁外出.
It should be noted that the wind circle of the Typhoon is not perfectly circular, influenced by the terrain, Moving speed, and other factors, it tends to present an elliptical or irregular shape, and the wind circle on the wind side is usually larger than the back wind side.
How should we respond?
When the weather forecast shows Typhoon is approaching, pay attention to the coverage of Level 7 and 10 windshields. If the residence is expected to go to Level 7, check the door windows as soon as possible, retrieve falling objects such as balconies, and reserve the necessary livelihoods. If the Forecast indicates Go to Level 10, prepare the highest level of defense to ensure that the personnel remain in the safe room.
Closed at Worry about shutdown, shutdown arrangements, which are usually linked to typhoon early warning signals issued by the local weather department (such as yellow, orange, red early warning). Standards may vary from place to place, subject to local government publication.In general, as the wind force increases, the level of early warning increases, the corresponding social response measures will gradually be upgraded.
