Downburst Hits Parts of Brisbane, Australia! (credit: Paul Nelson via 7 News Brisbane via Meteo Europe)
DISCUSSION: As strong storms fired up across parts of eastern Queensland during the daytime hours on 12 November (U.S. time) or 13 November (eastern Australia time), there were favorable conditions in place for thunderstorms capable of producing strong gusty winds and even downbursts in some cases. Downbursts tend to occur in association with thunderstorms when air which is sent upward via the core updraft reaches its maximum height and begins to start descending back through the most intense parts of the thunderstorm. As the air continues to descend (rather than warming) it rapidly cools as a result of the associated rainfall entering the space beneath the thunderstorm which typically has much lower relative humidity values. These combined factors act to speed up the rate of descent towards the ground and often will hit the surface with violent repercussions. As seen in the video above, this is well illustrated by the violent winds ripping through the roadways running parts of eastern Queensland, Australia!
