What is sinking in a thunderstorm?
A microburst is a localized column of sinking air (downdraft) within a thunderstorm and is usually less than or equal to 2.5 miles in diameter. Microbursts can cause extensive damage at the surface, and in some instances, can be life-threatening.
What is a downdraft and what causes it?
What Causes a Downdraft? Downdraft is caused by something called the stack effect, which is when warm air rises, leaving less air closer to the floor. … The force of the air comes down and pulls smoke with it, resulting in a downdraft of smoke coming out into your living room.
Is a microburst worse than a tornado?
Although microbursts are not as widely recognized as tornadoes, they can cause comparable, and in some cases, worse damage than some tornadoes produce. In fact, wind speeds as high as 150 mph are possible in extreme microburst cases.
What is convective updraft?
Convection is the vertical transport of rising air in the atmosphere as a result of atmospheric instability. It can lead to condensation and cloud formation. Warm air masses rise when there is a positive lapse rate.
What are the three stages of a thunderstorm?
Thunderstorms have three stages in their life cycle: The developing stage, the mature stage, and the dissipating stage. The developing stage of a thunderstorm is marked by a cumulus cloud that is being pushed upward by a rising column of air (updraft).
