On the Mechanisms of Rain Formation in an Idealized Supercell Storm
Monthly Weather Review, 2015Abstract Deep convective storms produce raindrops through three mechanisms: condensation and coalescence growth of cloud liquid droplets (i.e., warm processes), melting of ice hydrometeors, and shedding from wet hailstones. To investigate the relative importance of these mechanisms and their contributions to exotic drop size ...

Effective Storm-Relative Helicity and Bulk Shear in Supercell Thunderstorm Environments
Weather and Forecasting, 2007Abstract A sample of 1185 Rapid Update Cycle (RUC) model analysis (0 h) proximity soundings, within 40 km and 30 min of radar-identified discrete storms, was categorized by several storm types: significantly tornadic supercells (F2 or greater damage), weakly tornadic supercells (F0–F1 damage), nontornadic supercells, elevated right ...

Observations of Lightning in Convective Supercells within Tropical Storms and Hurricanes
Monthly Weather Review, 1994Cloud-to-ground (CG) lightning observations from land-based lightning detection networks now allow monitoring this component of the electrical structure of tropical storms and hurricanes within a few hundred kilometers of the United States coastline.

Streamwise Vorticity: The Origin of Updraft Rotation in Supercell Storms
Journal of the Atmospheric Sciences, 1984Abstract Linear (small amplitude) theory of shallow, inviscid, isentropic convection in a dry, unstably stratified, nonrotating atmosphere is used to investigate the rotational characteristics of an isolated, incipient convective storm in strong environmental shear. Environmental winds veering with height are associated with streamwise vorticity (i.e.,

A numerical investigation of supercell storm interactions with the urban environment
It is well known that cities can modify rainfall distributions, particularly by more frequently triggering deep moist convection over and downwind of urban areas. However, the effect of cities on organized convection, such as supercells, has been poorly studied.Francesco De Martin +4 more
