all about thunderstorm

1. THUNDERSTORM

2. Cumulonimbus cloud- is a dense, towering cloud associated with thunderstorms and severe weather. It forms when warm, moist air rises rapidly into the atmosphere, cooling and condensing into a massive, vertically developed cloud.

3. HAILSTONES - are solid balls or lumps of ice that form inside thunderstorms due to strong updrafts. They vary in size, from small pellets to large stones.

4. 4 TYPES OF THUNDERSTORM SINGLE –CELL MULTI-CELL SQUALL LINE SUPERCELL

5. SINGLE –CELL- Also known as pulse storms, these are small, short-lived storms that typically last 20-30 mins. * They often bring brief heavy rain and lightning but rarely cause severe weather.

6. 2. Multi-Cell Consist of multiple storm cells at different life stages. They can produce heavy rain, lightning, hail and even weak tornadoes.

7. 3. Squall Line A long, narrow line of storms that form along or ahead of a cold front. These storms can bring strong winds, heavy rain, and sometimes tornadoes.

8. 4.Supercell Thunderstorm The most intense and dangerous type of thunderstorm. Characterized by a rotating updraft called a mesocyclone .

9. 4.Supercell Thunderstorm Can produce large hail, damaging winds, and strong tornadoes.

10. Mesocyclone -is a rotating column of air, typically 2-10km (1-6miles) in a diameter, that forms within a severe thunderstorm . It develops when strong wind shear (changes in wind speed and direction with high height) causes air to rotate horizontally.

11. Lakhs volts - refers to a voltage measurement in hundreds of thousands of volts. 1 lakh volts=100,000 volts(or 100kV) 10 lakh volts= 1’000,000 volts (or 1megavolt mv) 1 kV (kilovolt)= 1,000 volts

12. WHAT TO DO WHEN THERE IS A THUNDESTORM

13. BEFORE Create a preparedness plan. Learn about your area’s thunderstorm risk and how to be warned of an approaching thunderstorm. Trim and remove dead and rotting trees and other objects that could fall and may cause injury. Close the windows and doors to prevent objects from being blown inside the premises.

14. BEFORE Stay inside the house or classroom. Remember to ensure a proper drainage for the rainwater before the thunderstorm.

15. DURING Stay calm. Wear warm clothes. Stay away from trees, towers, fences, electric and telephone lines if you are in an open area. Watch out for falling objects and power lines from posts for electricity and telephone lines.

16. DURING Postpone all outdoor activities. Unplug and turn off all the appliances such as television and computers. Electric surges and lightning may cause damage to all of these. Use battery-operated radio for gaining information instead. Move to the lowest floor of the building or house or any safe place within the building without windows or glass doors.

17. If you are in an open area and can’t find a shelter, put your feet together with heel touching each other(tiptoe position) while in a squat position. The logic is to transfer the lightning’s electricity from one foot to the other so that it goes back to the ground. If you don’t do this, the lightning might go to your heart and may cause death. While doing this, make sure you put your hands over your ears to protect your ears from thunder.

18. AFTER If the weather condition allows, go outside to check for any damages to your property. Still practice the safety measures and continue listening to the news for updates and instructions. Stay away from the damaged areas and watch out for damaged power cables.
