Following an earlier diagnostic study, the present paper performs numerical simulations of the rare wintertime supercell storms during 19–20 December 2002 in a subtropical environment near Taiwan. Using Japan Meteorology Agency (JMA) 20-km analyses and horizontal grid spacing of 1.5 and 0.5 km, the CloudResolving Storm Simulator (CReSS) of Nagoya University successfully reproduced the three maj...

The probability of occurrence of ice crystal number densities in young cirrus clouds is examined based on airborne measurements. The observations have been carried out at midlatitudes in both hemispheres at equivalent latitudes (52 − 55 N/S) during the same season (local autumn in 2000). The in situ measurements considered in the present study include temperatures, vertical velocities, and tota...

Large-eddy simulations (LESs) were performed for neutrally-stratified turbulent flows within and above a homogeneous plant canopy. 100 realizations of a three-dimensional turbulence field obtained from each of four LES runs, which di¤er in the driving force of the flow and the size of computational domain, were used in the present study. A conditional sampling technique was used to construct en...

Combustion of agricultural residues and wastes for energy applications is still popular. However, combustion biomass with different shapes leads to many side effects such as agglomeration, emission incomplete combustion. The aim this study was therefore investigate the on characteristics in an updraft chamber. rubber wood chip, coconut shell, oil palm empty fruit bunch, corn straw, sawdust, mix...

Abstract The current study identifies and quantifies various mechanisms of entrainment, their diluting effects, in the developing mature stages a simulated supercell thunderstorm. two stages, differentiated by lack or presence rotating updraft, are shown to entrain air different, but related that result from strong vertical wind shear environment. greatest entrainment rates stage asymmetric ove...

Abstract This study investigates whether quasi-random surface vertical vorticity is sufficient for tornadogenesis when combined with an updraft typical of tornadic supercells. The viability this pathway could mean that a coherent process to produce well-organized rather unimportant. Highly idealized simulations are used establish random noise as possible seed the production tornado-like vortice...

The evolution of the mesoscale flow and precipitation distribution are investigated for a small mesoscale convective system (MCS) that evolved in a nearly barotropic environment exhibiting moderate instability and weak wind shear. Observations primarily from a single Doppler radar detail the growth of the MCS from the merger of several clusters and lines of vigorous convective cells into a matu...

This study investigates the possibility of applying a large-scale solar updraft tower power plant in India with local ground conditions as an environmentally friendly and economically viable energy source. A reference model Solar Updraft Tower Power Plant (SUTPP) is constructed to examine influence most prominent dimensional parameters, including collector radius (RCollector), height (HTower), ...

The sensible heat budget of a large-scale area containing an idealized tropical cloud cluster is analyzed. The cluster is assumed to have spatial dimensions and precipitation rates typical of observed cloud clusters. In its early stages of development the idealized cluster consists of isolated deep precipitating convective cells, or "hot towers." A simple model using the assumed precipitation r...
