What is a Tornado And how do they form?

A violently rotating column of air, pendant from a cumulonimbus cloud, and nearly always observable as a "funnel cloud”

Many tornadoes develop in a special type of thunderstorms called “supercell”. Supercells are thunderstorms that are 10-16 km in size and rotate.

WARNING!!!

The watch was issued at 1:30pm, 4 hours and 11 minutes before the tornado reached Joplin! The watch further said there is a “high” probability of tornadoes and a “moderate” probability of a tornado of F-2 intensity or greater.

Equipment used

Satellites and radar are remote sensing tools that are vital because it allows meteorologists to see what the atmosphere is doing from a distance. They also need to know what the atmosphere is doing at all levels, which is why they send up weather balloons that track different meteorological variables as they rise, including temperature, wind, and moisture. Finally, they use computer models to input all these data and simulate future weather.
