A video out of Nevada shows a monsoonal shower collapsing in on itself, creating what we call a downburst or a microburst.
This occurs when dry air begins to mix into rainfall in a thunderstorm, forcing droplets to evaporate and thus calling what we refer to as evaporative cooling. When this happens air aloft becomes heavier as cold air is more dense than warm air and thus the heavier air rushes towards the surface sometimes at speeds up to 100-150mph.
Due to dry air being more common in the southwestern portions of the USA this phenomena is more common there, but it can still take place from time to time in Florida.
In June, a downburst damaged multiple structures at the Mystic Jungle Educational Facility.
Microburst damage can often be confused with tornado damage as well due to the strength of their winds. But they have a pronounced damage pattern with the damage being laid out in circular pattern away from the point of origin where the downburst took place.
Ted Fujita the creator of the Fujita scale with Tornado damage was the first person to notice this when he investigated the crash of Easter Airlines Flight 66 in 1975. He noticed the damage pattern in the area to be similar to that of the bombings of Hiroshima, which he also surveyed years prior. That bomb exploded above the surface of the earth with an airburst thrusting downwards, much like that of a meteorological downburst.
If you are curious between the difference between a microburst and a downburst.
The NWS office term for it is. "Downburst is the general term for all localized strong wind events that are caused by a strong downdraft within a thunderstorm, while microburst simply refers to an especially small downburst that is less than 4 km across."
