Abstract: Numerical simulations of three gust-front cases that occurred in northeastern Colorado during the summers of 1991 and 1992 am presented. The simulations are initialized with radar-derived winds and, for the two cases in ...

Abstract: In using a dual-wavelength radar system to detect hail, erroneous positive hail signals can result because of the stronger attenuation of the shorter wavelength radar beam. We present a simple technique to correct for ...

Abstract: The detection of hail with a dual-wavelength radar system can succeed only when the two essentially independent radars used are correctly calibrated, when attenuation is correctly handled, and when the radars sample the ...

Abstract: raveling deep tropospheric disturbances of wavelengths ~1500 km (short waves) have long been known to play an important role in the initiation and maintenance of warm-season convection. To date, relatively few studies have ...

Abstract: In the warm season the optically clear boundary layer often contains scatterers that can be detected by sensitive radars to distances of 50?100 km. Inhomogeneities in the field of reflectivity lead to echo patterns that ...

Abstract: During the warm season in the central United States there often exists a corridor of precipitation where a succession of mesoscale convective systems (MCSs) follow similar paths lasting several days. The total cumulative ...

Abstract: In a recent radar-based climatological study of warm-season precipitation over the continental United States, Carbone et al. found a high frequency of long-lived coherent rainfall episodes. Many of the events were of longer ...

Abstract: Computations of air motion and precipitation growth using winds derived from Doppler radar measurements were analyzed to reveal important flow features that influenced the production of precipitation during the nearly ...

Abstract: Air and particle trajectory calculations using internal motions from Doppler radar observations are used to identify kinematic feature and hail growth processes operating in a supercell storm that occurred on 2 August 1981 ...
