This study examined the roles of heat fluxes from Kuroshio Current in enhancing a frontal convective rainband associated with an extratropical cyclone that brought record-breaking heavy rainfall to Miyake Island, Japan, January 2017. A simulation (control experiment) and sensitivity experiments without sensible latent were conducted using regional cloud-resolving model. The developed along non-...

The use of solar chimneys for energy production was suggested more than 100 years ago. Unfortunately, this technology has not been realized on a commercial scale, in large part due to the high cost of erecting tall towers using traditional methods of construction. Recent works have suggested a radical decrease in tower cost by using an inflatable self-supported tower consisting of stacked toroi...

The convective nature of Stratocumulus topped boundary layers (STBL) involves the motion updrafts and downdrafts, driven by surface fluxes radiative cooling, respectively. balance between shear buoyant forcings at can determine organization cellular roll structures. We investigate effect varying top STBL using Large Eddy Simulations, taking DYCOMS II RF01 as a base case. focus on spatial identi...

Abstract. The dendritic growth layer (DGL), defined as the temperature region between −20 and −10 ∘C, plays an important role for ice depositional growth, aggregation potentially secondary processes. DGL has been found in past to exhibit specific observational signatures polarimetric vertically pointing radar observations. However, consistent conclusions about their physical interpretation have...

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...
