Of course, winds are rarely unidirectional, so let's look at a more complex case. At the location of the radar (and therefore near the surface), the maximum inbound velocity is just to the south, and the maximum outbound velocity is to the north. Connecting the inbound velocities to the outbound, we see that the wind is probably blowing from the south and perhaps slightly from the west. The speed is about 20 to 25 m s-1, as shown by the maximum and minimum values just next to the radar location.
Let's next determine the winds at the level of the first range ring.
