Wind barbs follow the same convention as Fig. (a) Time–height cross section from soundings launched at Amarillo. Plotted are vertical profiles of wind direction and speed (m s −1) at 1801, 1955, 2104, 2204, and 2303 UTC. VAD analysis from Amarillo WSR-88D 4.5° survelliance scans. An isochrone analysis of the thinline position is shown in (f) for the times in (a)–(e). Inset in (a) is a schematic of horizontal convective roll circulations. Thick black arrows in (a)–(d) point to horizontal convective rolls. Superimposed upon the reflectivity data are winds (full barb-5 m s −1, half-barb-2.5 m s −1), potential temperature (K), and mixing ratio (g kg −1) from surface stations and the P-3 and Electra aircraft.
#AMARILLO RADAR IN MOTION SERIES#
Time series of 0.5° survelliance scans of radar reflectivity (dB Z e) from 2005 UTC 6 May to 0015 UTC. Thinline observations of the dryline from Amarillo and Lubbock are indicated by the thick solid lines. The locations of Amarillo and Lubbock, Texas, are indicated by the star and solid circle, respectively.
Plotted are the surface winds (full barb-5 m s −1, half-barb-2.5 m s −1), temperature (☌), dewpoint (☌), and weather conditions. Surface charts at 21 UTC on 6 and 7 May, respectively. The stars indicate positions of soundings and the WSR-88D near Amarillo. Base map showing the Electra (black solid line) and P-3 (black dashed line) flight tracks relative to the dryline (thick gray lines) position on.
