This is the effect of creating your own wind. This can be experienced by driving down the road. If there is no wind and you are driving 25mph and you stick your hand out the window, you will feel the effects of 25mph of wind. As an added twist if you are driving 25mph and the wind is blowing 25mph from your right, then you will feel a wind 45 degrees off the front of the car with a strength of sqrt(2)*5.
