Many weather observers use things such as weather stations and weather radar to help keep a close eye over pending weather storms including thunder.  Interesting though, it has been known for some thunderstorms, can be created on both Venus and Jupiter and not just here on Earth. Every year, the Earth experiences an average of 25 million lightning strikes during some 100,000 thunderstorms. Thunder and lightning were regarded as diabolical, so during a thunderstorm monks tried to constantly ring the bells.
In 1935, an American tourist, Randolph Eastman, during a thunderstorm asked to stay in her house until the storm ended.
Severe thunderstorm frequency normally tops out at the start of June, or near the time when peak heating of the Sun is still attacking the last of Winter's leftover chill.


On occasion, on the rear flank of a convective system responsible for a progressive derecho, a nearly stationary band of thunderstorms may form. As the collisions and freezing continue to occur, and the charges at the top and bottom of the cloud increase, the electric field becomes more and more intense -- so intense, in fact, that the electrons at the Earth's surface are repelled deeper into the Earth by the negative charge at the lower portion of the cloud.
The development of a thunderstorm's downdraft ordinarily marks the dissipation stage of that particular storm. As a result, striking shelf clouds on occasion occur in conjunction with relatively benign thunderstorms. Even though scientists all over the world are gathering facts about lightning, dividing it into different types, measuring its voltage, monitoring temperature, and creating it in laboratories, it is still impossible to predict the behavior of every lightning bolt.


Most thunderstorms last about 30 minutes and are typically about 15 miles (24 km) in­ diameter. To understand why thunderstorms occur more often during the warm months requires some understanding of thunderstorm basics.Thunderstorms thrive under certain conditions.
