Abstract: novel method of retrieving the mean axis ratio (width/length) and standard deviation of orientation angles (σ?, which is called herein the intensity of fluttering) of ice cloud particles from polarimetric radar data is ...

Abstract: This note documents the results of more exact parameterizations for continuous-collection growth and evaporation against simpler traditional ones. Although the main focus is on improving research models, the research results ...

Abstract: In the first part of this paper, the characteristics of microburst-producing storms are examined with a three-dimensional cloud model using soundings from the Cooperative Huntsville Meteorological Experiment (COHMEX). With ...

Abstract: The simplified version of the Berry and Reinhardt parameterization used for initiating rain from cloud droplets is presented and is compared with 12 other versions of itself from the literature. Many of the versions that ...

Abstract: A single-moment bulk microphysics scheme with multiple ice precipitation categories is described. It has 2 liquid hydrometeor categories (cloud droplets and rain) and 10 ice categories that are characterized by habit, size, ...

Abstract: The minimal aliasing local spectral (LS) method is a numerical technique that embodies features of both finite-difference (FD) and spectral transform (ST) methods. Anderson first described this method in the context of the ...

Abstract: The authors document some of the unusual rotating updrafts (one of which produced a tornado) that developed over central Oklahoma on 28 October 1998 in an environment of strong (1.8 ? 10?2 s?1) low-level (0?3 km) mean ...

Abstract: The life cycle of the 2 June 1995 Dimmitt, Texas, tornado cyclone, observed during the Verification of the Origins of Rotation in Tornadoes Experiment (VORTEX), is described. The tornado cyclone here is defined as a ...

Abstract: Very few studies on nocturnal tornadoes have been performed, and operational forecasting of nocturnal tornadoes is often guided by the results of studies that are biased toward daytime tornadoes. However, it is likely that ...

Abstract: It is hypothesized that the precipitation intensity beneath a supercell updraft is strongly influenced by the amount of hydrometeors that are reingested into the updraft after being transported away in the divergent ...
