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...

A dryline is the zone of distinct moisture gradient separating warm, moist, and hot, dry air masses. It usually associated with mesoscale phenomena plays a significant role in atmospheric boundary layer (ABL) dynamics including initiation convection/thunderstorms. In tropical Indian region, these conditions are normally pre-monsoon season. present study, characteristics over rain shadow region ...

Abstract Submesoscale motions within the stable boundary layer were detected during Shallow Cold Pool Experiment conducted in Colorado plains, Colorado, U.S.A. 2012. The submesoscale motion consisted of two air layers creating a well-defined front with sharp temperature gradient, and further-on referred to as thermal submesofront (TSF). semi-stationary TSFs their advective velocities are determ...

Abstract Within the period 2014–2017, five hail events were reported in city of Surabaya Indonesia. Although deep convection commonly develops over Maritime Continent, severe thunderstorms triggering develop less frequently as specific atmospheric conditions are required. The rapid urbanization might have led to increased heat release atmosphere and deepening convection, which raises question w...

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...

The electtical conductivity existing in electrified clouds is computed under the assumption that a primary positive dipole charge distribution exists within the cloud and that the small ion concentrations are controlled by the rate of ion production from cosmic ray ionization, and by the rates of ion loss from the separate processes of ion recombination, diffusion, and conduction. The results s...
