Color Plate 4

a

The Doppler velocity field of a nearly two-dimensional squall line observed with the WSR-88D Doppler radar in Norman, Okla., on 4 May 1989

b

The Doppler velocity field of Hurricane Bob at 1902 UT, 19 August 1991, observed with the TDWR radar in eastern Massachusetts.

(a) The Doppler velocity field of a nearly two-dimensional squall line observed with the WSR-88D Doppler radar in Norman, Okla., on 4 May 1989 (the reflectivity field of this storm is in Fig. 9.46). The radar is located at the circle near the left border of the figure. County lines and villages in Oklahoma are presented. The velocity (m s-1) categories are presented next to the color bar.

(b) The Doppler velocity field of Hurricane Bob at 1902 UT, 19 August 1991, observed with the TDWR radar in eastern Massachusetts. Range circles are 10 nautical miles apart, elevation is 1.2°, and velocity (knots) is on the color bar. (Courtest of T. McDonagh, Raytheon.) larger image

c

The Doppler velocity field of a cold front passing a stationary dry front observed with the Oklahoma City WSR-88D Doppler radar on 30 April 1991, 2220 UT.

d

Doppler velocity display of three vertically stacked jets observed with the WSR-88D in Norman, Okla.

(c) The Doppler velocity field of a cold front passing a stationary dry front observed with the Oklahoma City WSR-88D Doppler radar on 30 April 1991, 2220 UT. (Thin lines of reflectivity marking the intersecting fronts are in Fig. 9.50.) Color bars categorize velocity in knots. Color labeled "RF" tags areas where range folded echoes interfere (Chapter 7).
