Exercise: Determining Storm-Relative Surface Winds
Question 1 of 3
Which vector best represents the direction (not magnitude) of the surface storm-relative winds? Assume the storm moves with the mean wind. (Choose the best answer.)
The correct answer is b.
Review the diagram to see how we determine the mean wind as the midpoint on the 0-6 km straight hodograph, and then re-orient the x-y reference frame (xs, ys) to plot the storm relative wind.
Question 2 of 3
Which vector best represents the direction (not magnitude) of the surface storm-relative winds? Assume the storm moves with the mean wind. (Choose the best answer.)
The correct answer is c.
Review the diagram to see how we determine the mean wind as the midpoint on the 0-6 km straight hodograph, and then re-orient the x-y reference frame (xs, ys) to plot the storm relative wind.
