How Does a Severe Thunderstorm Form?

Severe Thunderstorms form when water vapor, and rising air mix together. When warm air rising and cold air from possibly hills, mountains or sea breezes. A severe thunderstorm is usually made out of cumulonimbus clouds andalso requires a cold front.

How has Thunderstorms Impacted our life as Humans

We now have weather tools that our meteorologists use such as NOAAstorm prediction that help us predict when there is bad weather upon us. We have technology such as radio's, computers, and TV's to keep us up to date on weather forcasts. Sometimes knowing the weather before hand can help us prepare our property such as cutting branches so no winds come and blow them into our home and making sure our windows and doors are shut tightly. We have learned over the years to stay inside 30 minutes after seeing lighting or hearing thunder. We know to stay in rooms without windows such as a basement or any room without windows and to stay at low grounds.
