For those that use bufkit...I've been doing alot lately playing with those values next to the momentum transfer option (1, 10, 20, and 30). I know that they correlate to mixing strength and depth of the mixing layer, however, I don't really understand more beyond this and I've tried to find some information online. What do you want to be looking at and looking for when deciding which of the thresholds to use? The differences in terms of wind potential can be HUGE too. For example, at EWR tomorrow night...if you set the threshold at a 1 you get like no gust potential, however, if you set it at a 10 all of a sudden you're talking about 25-35 knot gusts.
