How Tornadoes Form:

Tornadoes form from severe thunderstorms, particularly those known as supercells. These powerful storms have a rotating updraft called a mesocyclone. Under certain conditions, the rotation can intensify and extend down to the ground, forming a tornado. Key factors in tornado formation include:

  1. Wind Shear: A variation in wind speed or direction with altitude.
  2. Lift: Provided by weather fronts or other atmospheric disturbances.
  3. Moisture: Necessary for storm development.
  4. Instability: Allows air to rise rapidly, fueling the storm.

Tornadoes in New Hampshire:

Tornadoes are relatively rare in New Hampshire compared to other parts of the United States. However, they do occur, especially during the late spring and summer months when conditions are favorable for severe thunderstorms. The state averages about one to two tornadoes per year.
