How strong can the downdraft in a microburst be?
Up to 6,000 feet per minute.
- Up to 6,000 feet per minute ✔
- Up to 600 feet per minute
- Up to 60,000 feet per minute
Why: A microburst is a small, intense downdraft that spreads out at the ground. It lasts only about 5 to 15 minutes, but can cause a huge loss of performance if you take off or land into one.
Huh, didn't know that: A typical microburst is surprisingly shallow, with a nominal depth of only about 1,000 feet.
What did one raindrop say to the other raindrop? Two's company. Three's a cloud.
