Moisture transport associated with the summertime North American monsoon.
The origins and transport of water vapor into the semi-arid Sonoran Desert region of southwestern North America are examined for the July-August wet season. Vertically-integrated fluxes and flux divergences of water vapor are computed for the 8 summers, 1985-1992, from ECMWF mandatory-level …

ISOTOPIC CONSTRAINTS ON ATMOSPHERIC MOISTURE TRANSPORT PROCESSES IN SOUTH AMERICA
… can provide us with insights into low-latitude moisture-transport processes in the modern climate system, recorded in paleoclimate proxy records, and in general circulation models that we rely on to understand how our climate is changing. Advances in satellite and groundbased instruments in the …

The Moisture Transport Properties of Cement Mortar under Salt Spray Deposition
The moisture transport properties of porous materials play a crucial role in building energy consumption and indoor thermal comfort. Due to the salt spray climate, the external boundary conditions of buildings in coastal areas differ significantly from those in inland regions. Under salt spray …

Modeling the impact of atmospheric moisture transport on global ice volume
… ice sheet mass balance. In most cases, poleward moisture flux is fixed and accumulation of snow only depends on local temperature. In this study, a simple coupled atmosphere-ice process model is introduced. An improved representation of the atmospheric hydrological cycle is included, and …

Multiscale modeling of moisture transport coupled with quality changes in selected foods
… and microbiological activity. Understanding the moisture transport is a necessary step to control food properties. Food processing unit operations, like drying and sorption, influence the behavior of foods. These processes alter many aspects of foods such as acceptability, nutritional value, …

Energy and Moisture Transport in the Earth Climate System: Mean State and the Perturbation Response
… are presented which investigate how energy and moisture transport define the mean state of the Earth Climate System and its response to perturbations. In the first study, we use a global climate model to study the effect of flattening the orography of the Antarctic Ice Sheet on climate. A …

Three-Dimensional Volume Averaged Soil-Moisture Transport Model: A Scalable Scheme for Representing Subgrid Topographic Control in Land-Atmosphere Interactions
In this research, the 3-D Volume Averaged Soil-moisture Transport (VAST) formulation is derived from the Richards equation to incorporate the lateral flow and subgrid heterogeneity due to topography. A conjunctive surface-subsurface flow model at a large scale, a 1-D Diffusion Wave (DW) surface …

Simulating the Dynamics and Influences of the West African Westerly Jet
… Across Scale (MPAS) in simulating the WAWJ, its moisture transport over West Africa, and its influence on Sahelian precipitation. Three types of climate dataset (observation, reanalysis, and simulations) were analysed in the thesis. The observation dataset (from the Climate Research Unit or …

A Lagrangian moisture source attribution model and analysis of southern Africa
Lagrangian moisture source attribution model is developed in order to explore the regional moisture source dynamics of southern Africa. In particular, the model was developed in order to explore the role of the regional land surface as a source of moisture for regional precipitation. This work was …

A modelling perspective on precipitationin the Indus River Basin: from synopticto Holocene variability
… Upper Indus Basin is related to cross-barrier moisture transport along the Himalayan foothills. The climate models analysed (IPSL-CM6-A, MRI-ESM2-0 and GISS-E2-1-G) generally reproduce this process well, but the seasonality of cross-barrier moisture transport is biased, resulting in …

Building Physics Tools: Needs, Use and the Lack of Use in the Building Process. Modelling Non-Isothermal Moisture Flow and Frost Penetration
… costs associated with building failures due to moisture problems and explores the reasons why these failures are persistent in the building industry. This is done by looking at the role of computer based tools, interviewing moisture consultants, analysing how they operate and what limitations …

The Influence of the North Atlantic Subtropical High on Atmospheric Rivers Over the Eastern United States
… (NASH). ARs are a major mechanism for meridional moisture transport often connected to heavy precipitation and mid-latitude troughs. The NASH, a semi-permanent anticyclone over the subtropical North Atlantic Ocean, has been shown to be significantly influential on precipitation variability over …

Experimental studies of sorption and transport of moisture in cement based materials with supplementary cementitious materials
… in cement based materials are closely related to moisture sorption and moisture transport properties. Therefore, it is important to study these properties, both theoretically and practically. This work is an experimental investigation in this field. Nowadays, the cement industry produces cements …

The cloud-radiative forcing of the U.S. landfalling atmospheric rivers
… (ARs) are narrow channels in the atmosphere that transport an enormous amount of moisture from the tropics to the higher latitudes. Streaks of highly reflective clouds are observed along with the ARs in satellite imagery. These clouds both influence the moisture transport of ARs, as well as modify …
