Transport of water vapor in the tropical tropopause layer [PDF]

Geophysical Research Letters, 2002
A trajectory model coupled to a simple micro‐physical model is used to explore the observed relationship between convection, water vapor and cirrus clouds in the tropical tropopause layer (TTL). Horizontal transport associated with the local Hadley circulation leads to water vapor minima in the winter hemisphere separated from the convective regions ...

Water vapor transport in snowpacks

, 2022
This thesis is an in-depth treatment of water vapor transport in snowpacks and its impacts on snow structure. The aim is to better understand this transport process and to lay the basis for a model representation in physics-based multi-layer snow models. Overall the process should improve the representation of the impact of snow in diverse environments

Tube transport of water vapor with condensation and desorption [PDF]

Applied Physics Letters, 2013
Attenuation and delay of active tracers in tube transport is an important current problem, but its full explanation is still lacking. To this end a model is introduced, where part of a tracer undergoes condensation and evaporation, treated as a diffusion-type process, in addition to Taylor dispersion.

Comparative Analysis of Individual Water Vapor Sources in Dry and Wet Year in Southwest China

Gaoyuan qixiang, 2023
The climate of Southwest China is wet all year round， but the frequent drought disasters in recent years have caused huge economic losses such as crop yield reduction and forest fire.In order to fully understand the anomalies of water vapor transport in ...

Contribution of mixing to upward transport across the tropical tropopause layer (TTL) [PDF]

, 2006
During the second part of the TROCCINOX campaign that took place in Brazil in early 2005, chemical species were measured on-board the high-altitude research aircraft Geophysica (ozone, water vapor, NO, NOy, CH4 and CO) in the altitude range up to 20 km ...
