[Weather] Video of microburst, Tuscon AZ

Not humour at all, but a good video of what a microburst is. No wonder airliners had no chance.

No out climbing those winds. This is the best video I have seen on the subject. "microburst" is a misnomer and misleading.

Thanks for that great video. Yes, not just climbing out of the winds but the solid wall of water coming down, wow. Might want to turn on the carb heat for that rain. (Ha, Ha)

If interested, NOAA has rain fall frequency estimates at http://hdsc.nws.noaa.gov/hdsc/pfds/

It is cool site, just click on your location and you will get a 1 thru 1000 year storm table for 5 min. to 60 day duration rain events. We have to design our outdoor enclosures for this to make sure they don't ingest water and use data like this to pick a design point for performance. Just like water ingestion testing for aircraft certification for in flight and on the runway (rain + tire splash up for engines behind the gear config.).

As an example per the NOAA tables in Kansas City each year we get a 5 minute storm that puts 0.4" inch on the ground, every 10 years 0.7", thats 8"/hour rate.

It would be interesting to know what the rainfall was and see what "kind" of storm it was.

About 12 years ago I was running a tower crane in Butner, NC near Durham. A storm cam through just after 7 am- it knocked the power out to the crane and then the wind caught it and blew it around downwind, the back window blew in with winds that I thought were over 100mph. Just about the hairiest situation I was ever in
