Question

Draw a short (about 1 cm) arrow perpendicular to your 0-Doppler wind speed boundary line through the Minneapolis radar site (black dot). Place an arrowhead on the end in the red area to indicate the Doppler-detected wind direction at the station. The direction of your arrow, signifying the wind direction in the lower layers of the atmosphere sensed by the radar signal, is generally from the ________.

A. East
B. West
C. North
D. South

Answer 1

The arrow should be pointing towards the East in the lower layers of the atmosphere sensed by the radar signal.

Step-by-step explanation:

To draw a short arrow indicating the wind direction in the lower layers of the atmosphere sensed by the radar signal, we need to consider the concept of relative velocity. When an airplane is affected by wind, its velocity relative to the ground is not the same as its actual velocity. In this case, the red area indicates the Doppler-detected wind direction at the station. Since the arrow is perpendicular to the 0-Doppler wind speed boundary line, the wind direction can be determined by considering the effects of the wind on the airplane's velocity.

Based on the given information and examples, the arrow should be pointing towards the East in the lower layers of the atmosphere sensed by the radar signal.
