What atmospheric conditions and locations are favorable for the formation of tornadoes?

These violent tornadoes are rare in occurrence. The key atmospheric ingredients that lead to tornado potential are instability – warm moist air near the ground, with cooler dry air aloft and wind shear – a change in wind speed and/or direction with height.

What are favorable conditions for a tornado?

Most tornadoes form from thunderstorms. You need warm, moist air from the Gulf of Mexico and cool, dry air from Canada. When these two air masses meet, they create instability in the atmosphere.

What are the primary requirements for the formation of T storms?

All thunderstorms require three ingredients for their formation: Moisture, Instability, and. a lifting mechanism.

What does instability mean when discussing the formation of a tornado?

Instability refers to unusually warm and humid conditions in the lower atmosphere, and possibly cooler than usual conditions in the upper atmosphere. … For instance, dry air in the middle atmosphere can be rapidly cooled by rain in the thunderstorm, strengthening the downdrafts that asist in tornado formation.

What cloud form is a sign of tornado formation?

Funnel clouds. A tornado is often made visible by a distinctive funnel-shaped cloud. Commonly called the condensation funnel, the funnel cloud is a tapered column of water droplets that extends downward from the base of the parent cloud.

What does a tornado smell like?
