Heavy Winds Alert: The Meteorological Department has said that in some districts of many states including Uttar Pradesh, Delhi, Uttarakhand, winds can blow at high speed this week. . It is estimated that during this time the wind speed can be 40 km per hour or more. Also, there may be rain showers with thunder. In such a situation, let us know what is the effect of wind speed and when it becomes dangerous.
How is the strength of winds measured
Wind strength is usually measured in two ways. The first is average or mean wind speed = average wind speed in a time interval of 10 minutes. The second is a gust of wind = a sudden increase in wind speed for a short period (usually a few seconds).
What will a 40 km/h wind do?
Due to continuous wind speed of 40-50 km/h, large branches of huge trees start swaying. If you go out with an umbrella in the wind of this speed, then the umbrella may overturn in the wind.
76-87 km/h
If the average wind speed is 76-87 km/h, it can break large tree branches. Can even blow off a tinshade or splash with force. Apart from this, high and big waves can rise in the sea. In such a situation, the Meteorological Department warns fishermen not to go to sea. Damage to life and property is possible due to winds of this speed.
Does the tree start getting uprooted at such a speed?
When the wind speed is 88-102 km/h, trees start getting uprooted. Winds of this speed can also damage buildings. When it rains with high speed winds, the soil becomes wet, as well as the weight of the tree has also increased due to getting wet in the water. In such a situation, these winds easily uproot them.
When the wind can cause heavy destruction
It happens very rarely that the wind speed is 103-117 km/h. But, these winds create havoc. They cause extensive damage to trees, houses, buildings including airports, telecommunication buildings, bridges and roads. These winds are very powerful and have the ability to blow away everything that comes in their way. Such winds are accompanied by torrential rains and lightning strikes at many places.
