Finally, you need lift. This can form from fronts, sea breezes or mountains. When are thunderstorms most likely to occur? Thunderstorms can occur year-round and at all hours. But they are most likely to happen in the spring and summer months and during the afternoon and evening hours.
How many thunderstorms are there every day? It is estimated that there are around 1, thunderstorms that occur across our planet every day. Are thunderstorms dangerous? Yes, despite their small size, all thunderstorms are dangerous. Every thunderstorm produces lightning, which kills more people each year than tornadoes. What is lightning? Lightning is a bright flash of electricity produced by a thunderstorm.
All thunderstorms produce lightning and are very dangerous. If you hear the sound of thunder, then you are in danger from lightning. Lightning kills and injures more people each year than hurricanes or tornadoes; between 75 to people. What causes lightning? Lightning is an electric current. Within a thundercloud way up in the sky, many small bits of ice frozen raindrops bump into each other as they move around in the air.
All of those collisions create an electric charge. After a while, the whole cloud fills up with electrical charges. The positive charges or protons form at the top of the cloud and the negative charges or electrons form at the bottom of the cloud.
Since opposites attract, that causes a positive charge to build up on the ground beneath the cloud. The grounds electrical charge concentrates around anything that sticks up, such as mountains, people, or single trees. The charge coming up from these points eventually connects with a charge reaching down from the clouds and - zap - lightning strikes!
Have you ever rubbed your feet across carpet and then touched a metal door handle? If so, then you know that you can get shocked! Lightning works in the same way. Credit: UCAR. Picture a thunderstorm - heavy raindrops beat the roof, lightning flashes through the windows, thunder booms, the dog whines from his hiding spot under your bed.
Now picture two thousand thunderstorms. Right now, at this very moment, there are about two thousand thunderstorms going on around the world. Even though thunderstorms are common, they are still dramatic events with intense rain, hail, wind, lightning, thunder, and even tornadoes.
As a storm rises into freezing air, different types of ice particles can be created from freezing liquid drops. The ice particles can grow by condensing vapor like frost and by collecting smaller liquid drops that haven't frozen yet a state called "supercooled". When two ice particles collide, they usually bounce off each other, but one particle can rip off a little bit of ice from the other one and grab some electric charge.
Lots of these collisions build up big regions of electric charges to cause a bolt of lightning, which creates the sound waves we hear as thunder. The Thunderstorm Life Cycle 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. The cumulus cloud soon looks like a tower called towering cumulus as the updraft continues to develop.
There is little to no rain during this stage but occasional lightning. The thunderstorm enters the mature stage when the updraft continues to feed the storm, but precipitation begins to fall out of the storm, creating a downdraft a column of air pushing downward. When the downdraft and rain-cooled air spreads out along the ground it forms a gust front, or a line of gusty winds.
The mature stage is the most likely time for hail, heavy rain, frequent lightning, strong winds, and tornadoes. There can never be thunder without lightning. Sign up for our Newsletter!

Why are there more thunderstorms during the summer? Cumulonimbus clouds often mean severe thunderstorms and other serious weather. Moisture Rapidly rising warm air.
