Final answer:
Wind directions around a mesocyclone are changing due to the rotational characteristics of the storm system, which meteorologists utilize for tornado prediction and understanding the dynamics of severe weather systems.
Step-by-step explanation:
From one location to another around the mesocyclone, the wind directions are Changing (C).
Wind direction and speed around a mesocyclone are not uniform because they are influenced by the mesocyclone's rotation. Meteorologists observe these changing wind patterns to assess the rotation in the atmosphere, which is essential for tornado prediction. The velocity vectors around a storm system like a hurricane or tornado clearly show wind circulation around the center or eye, where the wind speeds are highest.
In the case of a tornado, the difference in wind speeds at various altitudes causes a horizontal column of air to rotate and eventually shift into a vertical axis, leading to the formation of a tornado. Moreover, within the tornado, the rate of rotation increases as the radius decreases, verifying that wind direction and speed change continually within this dynamic system.
