Thunderstorm Video Lecture | Geography for UPSC CSE

Ans. A thunderstorm is a weather phenomenon characterized by the presence of lightning, thunder, heavy rain, and sometimes strong winds. It is caused by the rapid upward movement of warm, moist air that collides with cooler air in the atmosphere, resulting in the formation of cumulonimbus clouds.

Ans. Thunderstorms typically go through three main stages: the cumulus stage, the mature stage, and the dissipating stage. During the cumulus stage, warm air rises and forms towering cumulus clouds. In the mature stage, the updrafts and downdrafts within the storm are at their strongest, leading to heavy rain, lightning, and thunder. Finally, during the dissipating stage, the storm weakens as the updrafts subside.

Ans. The duration of a thunderstorm can vary greatly, but on average, they tend to last for about 30 minutes to an hour. However, some thunderstorms can persist for several hours, while others may dissipate within a few minutes. The specific duration depends on various factors such as the atmospheric conditions and the intensity of the storm.

Ans. Yes, thunderstorms can be dangerous. They are associated with several hazards, including lightning strikes, strong winds, heavy rain leading to flash floods, and even tornadoes in severe cases. These hazards can pose a risk to human safety and cause damage to property. It is important to take necessary precautions and seek shelter during thunderstorms to minimize the risk of harm.

Ans. To stay safe during a thunderstorm, it is recommended to follow these precautions: - Seek shelter indoors, preferably in a sturdy building, and avoid open areas, tall objects, and bodies of water. - If you are unable to find indoor shelter, crouch down low in a low-lying area and avoid being the tallest object around. - Stay away from windows, electrical appliances, and plumbing fixtures during a thunderstorm. - Unplug sensitive electronic devices to protect them from power surges caused by lightning. - Avoid using corded telephones and taking showers or baths during a thunderstorm. - If you are driving, pull over to a safe location, turn on your hazard lights, and stay inside the vehicle until the storm passes.
