thunderstorm, a violent short-lived weather disturbance that is almost always associated with lightning, thunder, dense clouds, heavy rain or hail, and strong gusty winds. Thunderstorms arise when layers of warm, moist air rise in a large, swift updraft to cooler regions of the atmosphere.
What usually happens during a storm?
A thunderstorm is a localized storm accompanied by lightning and thunder. It may also have gusty winds and often brings heavy rain. Some thunderstorms can also bring tornadoes and/or hail. During winter, localized heavy snow showers may also have thunder and lightning.

What are the 3 stages of thunderstorms?
Thunderstorms have three stages in their life cycle: The developing stage, the mature stage, and the dissipating stage. The developing stage of a thunderstorm is marked by a cumulus cloud that is being pushed upward by a rising column of air (updraft).
What causes a thunderstorm?
The Short Answer:
Unstable air forms when warm, moist air is near the ground and cold, dry air is above. Lift comes from differences in air density. It pushes unstable air upward, creating a tall thunderstorm cloud.
Is it safe to go out in a thunderstorm?
Thunder and lightning is a potential hazard which should be taken seriously when walking outdoors. It’s wise to familiarise yourself with what to do if you encounter a thunderstorm.

How long can a thunderstorm last?

What does long thunder mean?
If a lighting bolt is longer in distance, more air has to be displaced and thus more thunder that may reach your ears from slightly more directions. This could be perceived as rolling thunder, especially if you are a little further away from the storm.
What causes a thunderstorm to end?
As long as the updraft can keep feeding the thunderstorm warm, humid air, it will continue to grow and intensify. However, the downdraft will usually end up killing off the thunderstorm as it will cut off the updraft’s supply of warm, humid air. Once this happens, the storm goes into its last stage (Figure D).
Should you wash your hands or take a shower during a thunderstorm?

Where does lightning strike the most?
Lake Maracaibo
3. The most lightning-struck location in the world. Lake Maracaibo in Venezuela is the place on Earth that receives the most lightning strikes. Massive thunderstorms occur on 140-160 nights per year with an average of 28 lightning strikes per minute lasting up to 10 hours at a time.
Why do storms happen at night?
Thunderstorms that form at night occur in the absence of heating at the ground by the sun. Consequently, the storms that form at night are usually “elevated,” meaning that they form aloft above the cooler air near the ground, rather than near the ground, which only during the day can get warmer.
Has anyone died from showering during thunderstorm?

Can I watch TV during a thunderstorm?
It isn’t dangerous to watch TV during a thunderstorm, but the electronics in a TV set are vulnerable. If you have to make a telephone call, use a mobile phone detached from its cable rather than a landline device. Over-voltages resulting from a lightning strike may follow electrical conductors into the handset.
Why does thunder shake the house?
Why does the house shake when there is a thunder storm? Your house will shake depending the closeness of the lightning. Thunder is a sonic boom that comes from the rapid heating of the air around a lightning strike. Sonic booms cause massive shaking to nearby objects (your house).
Can I charge my phone during a thunderstorm?
