What causes updraft?
Updrafts are found when a wind blowing at a hill or mountain has to rise to climb over the hill. Updrafts can also be caused by the sun heating the ground. The heat from the ground warms the surrounding air, which causes the air to rise. The rising pockets of hot air are called thermals.
Why do updrafts rotate?
When winds intensify, the force released can cause the updrafts to rotate. This rotating updraft is known as a mesocyclone. For a tornado to form in this manner, a rear-flank downdraft enters the center of the mesocyclone from the back. Cold air, being denser than warm air, is able to penetrate the updraft.
How are updrafts created?
What is updraft and downdraft?
updraft and downdraft, in meteorology, upward-moving and downward-moving air currents, respectively, that are due to several causes. Local daytime heating of the ground causes surface air to become much warmer than the air above, and, because warmer air is less dense, it rises and is replaced by descending cooler air.
What causes a downdraft in a thunderstorm?
The falling particles drag air down with them. This sinking air is referred to as downdrafts. Entrainment into the downdraft results in some evaporation of the precipitation, which causes a cooling which makes the air more dense, thus increasing the downdraft.
Can a mesocyclone touch down?
In rare cases, the entire mesocyclone of HP supercells can touch the ground. The mesocyclone associated with the El Reno supercell nearly touched the ground as per mobile Doppler radar observations, making it nearly impossible to discern any storm related structures.

What causes updrafts and downdrafts?
Updrafts can also be caused by the sun heating the ground. The heat from the ground warms the surrounding air, which causes the air to rise. The rising pockets of hot air are called thermals . Downdrafts occur on the downwind side of a hill or mountain. Downdrafts are often found in the vicinity of strong thunderstorms.
What happens when an updraft condenses?
With enough moisture, the current may visibly condense into a cumulus or cumulonimbus cloud. The definition of an updraft is a strong upward current of air.
