The resulting thunderstorms are “very dangerous” for air travel, Struckmann said. This is due to the “severe turbulence caused by updrafts, downdrafts, winds and hail.”
Updrafts and downdrafts, along with wind shear in general, are a major contributor to airplane crashes during takeoff and landing in a thunderstorm. Extreme cases, known as downbursts and microbursts, can be deadly and difficult to predict or observe
The second method occurs during a supercell thunderstorm, in updrafts within the storm. When winds intensify, the force released can cause the updrafts to rotate. This rotating updraft is known as a mesocyclone. [8] For a tornado to form in this manner, a rear-flank downdraft enters the center of the mesocyclone from the back. Cold air, being ...
This area is precipitation-free and the site of widespread updrafts. The updrafts under a cumulonimbus can be extremely laminar, extensive, and uniform, this is particularly true during the buildup of the thunderstorm. [8] They can last more than one hour and correspond to a steady state of the cumulonimbus. [9]
For tornadoes to form, we need thunderstorms, which have very strong updrafts and downdrafts, said Bill Gallus, a professor in the department of Geological and atmospheric sciences at Iowa State ...

The updrafts and downdrafts within cumulonimbus clouds cause water molecules to freeze and solidify, creating hailstones and other forms of solid precipitation. [60] Due to their larger density, these hailstones become heavy enough to overcome the density of the cloud and fall towards the ground.
Ahead of a push of cold air on Sunday, the potential for thunderstorms packing strong wind gusts and flash flooding will extend from northern and central Florida to Maryland, Delaware and southern ...
