Land spout

Landspout: Sao tornados sem a presenca do mesociclone (NOAA, 2016).

The dynamics of "mesocyclone tornadoes" and "landspout tornadoes" are not completely understood, but because sufficient meaning and distinction are conveyed, these terms are widely used in both the scientific and lay communities.

Often this spinning air develops into a small vortex, known as a 'landspout' when over land and a 'waterspout' when over water.

A landspout is a small weak tornado which typically doesn't arise from a mesocyclone or a supercell but instead from less severe thunderstorms and other convective clouds.

These often are "stretched" by updrafts, forming the landspouts we sometimes see around airports like Denver International and those on the Florida coast.

Landspouts are usually small tornadoes formed from cloud systems and dust devils are also smaller, less harmful, members of the twister family.

A whole host of slang names for tornadoes have developed- in addition to `twister', other types of tornadoes are also known as dust devils, whirlwinds and landspouts.
