Quick, Sudden
If you stand in the wind it will be really quick to knock you over. So quick that you probably won't even know the wind did it. You'll end up standing up only to be knocked over again, just as quick.
Imagine how quick the wind knocks you over when you stand up. So quick, you don't even remember being up. Try again and count how many seconds it takes for it to knock you down. Less than one. Now that's quick.

That quick wind is quicker than you can say Satsuki (さつ). And "Satsuki" is a pretty quick sounding name already. Go ahead, say "Satsuki" as quick as you can right now. Heck, try it a few times.
Okay, pretty quick, but this wind is even quicker than that.
