Impact of deep convection in the tropical tropopause layer in West Africa: in-situ observations and mesoscale modelling
deep convection the tropical tropopause layer West Africa in-situ observations mesoscale modelling
2011/1/19
We present the analysis of the impact of convection on the composition of the tropical tropopause layer region (TTL) in West-Africa during the AMMA-SCOUT campaign. Geophysica M55 aircraft observations...
A model study on the influence of overshooting convection on TTL water vapour
overshooting convection TTL water vapour
2010/10/21
Overshooting deep convection that penetrates into the Tropical Tropopause Layer (TTL) is thought to have an important role in regulating the water vapour content of this region. Yet, the net effect of...
A climatological perspective of deep convection penetrating the TTL during the Indian summer monsoon from the AVHRR and MODIS instruments
deep convection the TTL the Indian summer monsoon the AVHRR and MODIS instruments
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...
Uncertainties in atmospheric chemistry modelling due to convection parameterisations and subsequent scavenging

2010/2/21
Moist convection in global modelling contributes significantly to the transport of energy, momentum, water and trace gases and aerosols within the troposphere. Since convective clouds are on a scale t...
Generation of free convection due to changes of the local circulation system

2009/11/19
Eddy-covariance and Sodar/RASS experimental measurement data of the COPS (Convective and Orographically-induced Precipitation Study) field campaign 2007 are used to investigate the generation of near-...
Regional modelling of tracer transport by tropical convection – Part 2: Sensitivity to model resolutions
tracer transport tropical convection model resolutions
2009/9/27
The general objective of this series of two papers is to evaluate long duration limited-area simulations with idealised tracers as a possible tool to assess the tracer transport in chemistry-transport...
A statistical analysis of the influence of deep convection on water vapor variability in the tropical upper troposphere
deep convection water vapor variability tropical upper troposphere
2009/8/18
The factors that control the influence of deep convective detrainment on water vapor in the tropical upper troposphere are examined using observations from multiple satellites in conjunction with a tr...
Influence of different convection parameterisations in a GCM
different convection parameterisations GCM
2009/1/21
In global models of the atmosphere convection is parameterised, since the typical scale of this process is smaller than the model resolution. Here we address some of the uncertainties arising from the...
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...
Impact of land convection on troposphere-stratosphere exchange in the tropics
Impact of land convection troposphere-stratosphere exchange the tropics
2008/12/24
The mechanism of troposphere-stratosphere exchange in the tropics was investigated from space-borne observations of the horizontal distributions of tropospheric-origin long-lived species, nitrous oxid...
A study of the effect of overshooting deep convection on the water content of the TTL and lower stratosphere from Cloud Resolving Model simulations
overshooting deep convection TTL lower stratosphere Cloud Resolving Model
2008/12/19
Simulations of overshooting, tropical deep convection using a Cloud Resolving Model with bulk microphysics are presented in order to examine the effect on the water content of the TTL (Tropical Tropop...
Lightning and convection parameterisations – uncertainties in global modelling
Lightning convection parameterisations global modelling
2008/12/18
The simulation of convection, lightning and consequent NOx emissions with global atmospheric chemistry models is associated with large uncertainties since these processes are heavily parameterised. Ea...
