英文摘要: This paper describes observations and analysis of Doppler radar data from a down-looking 94GHz (W-Band) system operated from a NOAA WP-3 Orion research aircraft in Tropical Storm (TS) Karen. The flight took place on 5 October 2013; Karen had weakened with maximum winds around 20ms-1. Doppler spectral moments from the radar were processed to retrieve sea-spray microphysical properties (drop size and liquid water mass concentration) profiles in the height range 75-300m above the sea surface. In the high wind speed regions of TS Karen (U10>15ms-1), sea spray was observed with a nominal mass-mode radius of about 40μm, a radar-weighted gravitational fall velocity of about 1ms-1, and a mass concentration of about 10 -3gm-3 at 75m. Spray-drop mass concentration declined with height to values of about 10-4gm-3 at 300m. Drop mass decreased slightly more slowly with increasing height than predicted by surface-layer similarity theory for a balance of turbulent diffusion vs fall velocity. © 2014.
