COVID-19 pandemic has recently had a dramatic impact on society. The understanding of
the disease transmission is of high importance to limit its spread between humans. The …

During the 1950s and 1960s, when intensive investigations on atmospheric moist
convection were launched, two possibilities were identified for the basic element of moist …

We show how settling and phase change can combine to drive an instability, as a simple
model for the formation of mammatus clouds. Our idealised system consists of a layer (an …

We study numerically the melting of a horizontal layer of a pure solid above a convecting
layer of its fluid rotating about the vertical axis. In the rotating regime studied here, with …

The research network “Basic Concepts for Convection Parameterization in Weather Forecast
and Climate Models” was organized with European funding (COST Action ES0905) for the …

We examine an existing energy-consistent approach for modeling entrainment rate
coefficient, α, in the context of a volumetrically forced jet. The steady buoyancy forcing, with a …

An off-source volumetrically heated turbulent transient plume, known as transient diabatic
plume (TDP), is compared with an unheated transient plume (TP). Both the TDP and TP are …

We present a computational study of a forced plume subjected to volumetric off-source
heating in a stratified medium using large eddy simulations. A detailed validation of the LES …

We study the formation, longevity and breakdown of convective rings during impulsive spin
up in square and cylindrical containers using direct numerical simulations. The rings, which …

Physically-based cloud simulation is an effective approach for synthesizing realistic cloud.
However, generating clouds with desired shapes requires a time-consuming process for …
