Need help with this lab. Documents attached. In this example, the actual winds circulating around the mesocyclone all have the same speed, as shown by arrows whose lengths are [(the same)(different). Lab 7A and 7B from the module.

Doppler radar detects only those motions or components of motion that are directly toward or away from the radar. At two locations within the rotating wind pattern no air motion is detected by the Doppler radar beam. At those points, the actual wind blows along paths perpendicular to the radar beam (dashed line). Hence, the Doppler radar senses no Doppler wind speed at these locations. These two locations are sensed by the radar when its beam is in the [(1)(2)(3)(4)(5)] position. Draw a small circle around each of the dots associated with those two arrows to denote this 0-Doppler wind speed.
