As a result, thunderstorms in the tropics because the air has a very high temperature and humidity made the air there is no stability (instability), or the atmosphere is stabilized mixing up the mash from below and from above on the downward side. In the first step, the air flow up or caused severe (strong convective updraft) and in the next step, which is the decay (dissipating stage) will have serious down flow air flow (strong downdraft) inside the column (range) of rain. This frequent thunderstorm formation up to 40000-50000 feet in Middle latitude area (mid-latitude) and higher than this in the tropics. The lower layer of the atmosphere is growing, the Strasburg stable spherical very good (great stability) can inhibit the formation of thunderstorm clouds. In meteorological thunderstorm can be divided into several types, but the nature of the passage of time, such as a air mass thunderstorm (air-mass thunderstorm) vertical sokwon thunderstorm (squall-thunderstorm) and a horizontal air impingement thunderstorm (frontal thunderstorm).
