Thunderstorm
Thunderstorm
• Thunderstorms and tornadoes are severe local storms. They 
are of short duration, occurring over a small area but 
are violent.
• Thunderstorm is a storm with thunder and lightning and 
typically also heavy rain or hail.
• Thunderstorms mostly occur on ground where the 
temperature is high. Thunderstorms are less frequent on 
water bodies due to low temperature.
• Worldwide, there are an estimated 16 million thunderstorms 
each year, and at any given moment, there are roughly 2,000 
thunderstorms in progress.

Stages in the development of 
thunderstorm are
Cumulus stage:
• Warm, moist air rises in a buoyant plume or in a series of convective 
updrafts. 
• As this occurs the air begins to condense into a cumulus cloud. As the 
warm air within the cloud continues to rise, it eventually cools and 
condenses. 
• The condensation releases heat into the cloud, warming the air. This, in 
turn, causes it to rise adiabatically. 
• The convective cloud continues to grow upward, eventually growing above 
the freezing level where super-cooled water droplets and ice crystals 
coexist Precipitation begins once the air rises above the freezing level

Mature stage
• It is characterized by the presence of both updrafts and downdrafts 
within the cloud. 
• The downdrafts are initiated by the downward drag of falling 
precipitation.
• Cold descending air in the downdraft will often reach the ground before 
the precipitation. 
• As the mature-stage thunderstorm develops, the cumulus cloud 
continues to increase in size, height and width.
• Cloud to ground lightning usually begins when the precipitation first 
falls from the cloud base. During this phase of the life cycle, the top of 
the resulting cumulonimbus cloud will start to flatten out, forming an 
anvil shape often at the top of the troposphere.

FAQs on PPT: Thunderstorm - Geography for UPSC CSE

1. What causes thunderstorms?
Ans. Thunderstorms are caused by the rapid upward movement of warm, moist air that collides with cool air. This collision creates a cumulonimbus cloud, which eventually leads to the formation of thunderstorms.
2. How long do thunderstorms usually last?
Ans. The duration of a thunderstorm can vary, but on average, they typically last for about 30 minutes to an hour. However, some severe thunderstorms can persist for several hours.
3. Can thunderstorms be dangerous?
Ans. Yes, thunderstorms can be dangerous. They are often accompanied by lightning, strong winds, heavy rain, and even hail, which can pose threats to human safety, property damage, and cause power outages.
4. Is it safe to use electronic devices during a thunderstorm?
Ans. It is generally advised to avoid using electronic devices during a thunderstorm, as lightning strikes can cause power surges that may damage the devices. It is recommended to unplug electronic equipment and avoid using them until the storm passes.
5. What should I do if I get caught outside during a thunderstorm?
Ans. If you are caught outside during a thunderstorm, it is important to seek shelter immediately. Avoid tall objects, open spaces, and bodies of water. Find a low-lying area or a building with grounded wiring and stay indoors until the storm subsides.
