Figure 4. Radial cross-section of reflecitivity and wind through
a cell in the north-east eyewall. The wind field was constructed
by placing Doppler observations in a frame of reference travelling around
the storm with the speed of the tangential wind, and thus placing the wind
more properly for the purposes of determining cell-relative motions.
Note the weak-echo region that is somewhat reminiscent of a bounded weak
echo region. Horizontal component represents radial motion from or
toward storm center, while vertical component is the vertical component
of the wind.
