b. Starting at the point where the first vector ended, plot the second
vector for the 2,000 to 4,000 meter layer which represents a wind
with a speed of 13 knots blowing from 1420 mils.
This vector is
plotted 14.2 kilometers long toward 4620 mils. Mark the end of this
vector with the number 4 to indicate 4,000 meter height and add a
small circle (Figure 2-7).
