Parameterizing deep convection using the assumed probability density function method
Parameterizing deep convection function method
2015/3/5
Due to their coarse horizontal resolution, presentday climate models must parameterize deep convection. This
paper presents single-column simulations of deep convection
using a probability density f...

2010/8/13
The impact of very deep convection on the water budget and thermal structure of the tropical tropopause layer is still not well quantified, not least because of limitations imposed by the available ob...
The tropical marine boundary layer under a deep convection system: a large-eddy simulation study

2009/1/7
In this second part of a series of two papers which aim to study the local impact of deep convection on the chemical composition of the Upper Troposphere and Lower Stratosphere (UTLS), we focus on ozo...
Modelling study of the impact of deep convection on the utls air composition - Part I: Analysis of ozone precursors
deep convection utls air composition ozone precursors
2009/1/7
The present paper (part I) is devoted to the analysis of the ozone precursors (CO, NOx and non-methane volatile organic compounds) and HOx in the UTLS. The simulation results show that the distributio...
