So for comparison:

"Light breeze" solar wind: 200 kilometers per SECOND

Category 3 Hurricane: 200 kilometers per HOUR (Cat5 is 252kph+)

Help me wrap my mind around this. I know that solar wind is not the same thing as earth wind, (mostly radiation vs. gases, correct?) but there has to be something of substance to it in order for us to be able to measure and put a number on it. How is the solar wind not scouring the dust off of the Moon - or is it, but not at a rate that's all that appreciable, due to the much lower density of solar wind, and how does something like solar wind affect astronaut EVAs?
