I'm not recommending using the takeoff as a snow removal technique, but fresh snow will blow off once a little wind gets on it. I do us this technique often with my cars and it works great. :-)

My experience (with watching snow blow off cars) is that it blows off
only from the very top surface, so takes quite a while to blow off
completely. Much more than a takeoff run - maybe a trip to my aunt's.
