Safety Measures Against Cyclones and Thunderstorms
Did you know that recently in Orissa they had an extremely severe Cyclonic Storm? It's named cyclone Fani.
But thankfully government had evacuated one million people in the entire cyclone hitting region before it hit.
It was all because of the technological advancement in weather forecasting. Many safety measures were taken.
Let's see some techniques governments use to forecast the weather.
The scientists use a simple device called Anemometer to measure the speed of the wind.
Let's learn about Anemometer.
Anemometer looks like this.
It consists of cup-like structures to measure wind speed based on their movement and also the direction of the wind.
When the wind blows and hits the blade of anemometer, they rotate. The more they rotate the more the wind speed.
Now let's see how radar and satellites are used to see the storms.
Satellites fly above the earth’s atmosphere. They have powerful cameras that can see the cloud formations from the space.
These kind of formations as shown, are storms cyclones. After detecting them we can say there is a storm coming soon.
Similarly, radar images are also used in weather forecasting to detect rainfall, snowfall using technology.
After forecasting a cyclone or thunderstorm, these safety measures are very helpful. We must follow them.
Now let's see what these safety measures are.
1. The government should warn people 24 hours in advance with the help of weather forecasting using satellites
2. Cyclone and Tornado shelters should be made for people living in cyclone-prone areas. These are rooms made underground and away from shores having no windows.
3. Quick communication to government agencies, fishermen, ports to make necessary arrangements and minimize destruction.
4. As an individual, when a cyclone or a tornado strikes, take shelter under tables, bow down and protect head and neck using arms.
5. Keep away from water in cyclone-hit areas as the water might be contaminated.
6. Stay inside houses. 7. Do not ignore warnings from the meteorological department.
8. Should have all emergency numbers.
9. Avoid driving on roads full of water as the roads might be damaged or the vehicle may get stuck with water going inside the machinery.
10. Cyclone/Tornado can cause damage to electric poles and it may cause a short circuit and electric shocks.
11. Cooperate and help others. Help injured and hungry people.
Anemometer is a device used to measure wind speed. Satellites and radars are used in weather forecasting.
We must follow the safety measures in the times of cyclones and thunderstorms.
