Supercell lightning is a product of a supercell thunderstorm, a rotating thunderstorm which has higher than normal electrical activity.  These storms produce the most intense and dangerous light shows on earth with the most highly charged cloud to ground lightning…

All hurricanes begin as a swirling mass of thunderstorms. In most cases, hurricane development goes no further; but in a few, the thunderstorms consolidate into a distinct tropical wave. The National Hurricane Center designates such areas of interest with a letter-number…

The thunderstorms that produce supercell lightnings are loners, if one was to personify them. While other forms of lightning clouds can be found in the same storm system, supercells have a tendency to form in areas several miles from the main storm front. They’re rare…

On September 16, 1987, 196 nation-states committed to ending ozone depletion by phasing out the use of chloroflurocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). The CFC Phase-Out Management Plan is complete: CFCs can no longer be found anywhere in the commercial market….

Every country has different seasons that their year is broken up into.  Thailand is very unique in that it has three seasons and they don’t seem to differ much in the temperature, but the rainfall amount varies quite a bit…

Supercell lightning is lightning that is produced during a supercell thunderstorm, the least common, yet the most severe of all  thunderstorms. Supercell lightning occurring during a supercell thunderstorm can be deadly, with tens of thousands of lightning strikes or very…
