Answer the questions to guide you through interpreting the winds in this radar image.

Roughly, from what direction is the wind blowing at the following levels: at the surface, at the location labeled "A" and the location labeled "B"? (Choose the best answer.)

Radial velocity image

The correct answer is c.

Radial velocity image with arrows denoting how to interpret wind direction.

If we draw the radials beginning at the radar and intersecting the zero isodop at these locations and then draw a perpendicular line to indicate the wind direction, we see that it is east at the surface, southeast at the location of the first range ring, and south at the location of the second range ring.
