The representation of the Kalahari thermal low and its induced circulations over Southern Africa in observations and models
… favours the development of an anomalous moisture flux convergence that triggers the deep convection and leads to more rainfall. Furthermore, the accurate representation of the Hadley circulations over southern Africa revealed the coexistence of both shallow and deep Hadley circulations …

Model Estimation of Depression-focused Groundwater Recharge and its Variability in the Canadian Prairies
… a soil-water-balance model named Versatile Soil Moisture Budget-Depression Upland System (VSMB-DUS). Automated digital elevation model (DEM) analysis was used to identify topographical depressions across Alberta and Saskatchewan and to determine hydrologically relevant parameters. Hourly …

North American monsoon precipitation and its precursors: processes at the seasonal and diurnal scale
… between precipitation and the other moisture budget variables, the large-scale flow, and atmospheric stability on the seasonal and diurnal scales. On both the seasonal and diurnal scale, flow was key to the location and intensity of precipitation. In 2004, the subtropical high over …

Land-ocean contrasts under climate change
… can be understood using a conceptual model of moisture transport between the land and ocean boundary layers and the free troposphere. Changes in P - E over ocean are closely tied to the local surface-air temperature changes via a simple thermodynamic scaling; the so-called "rich-get-richer" …

Interactions between Atmospheric Deep Convection and the Surrounding Environment
… the vertical distribution of energy and moisture in the atmosphere, modulating the hydrological cycle, and altering Earth's energy balance. However, many interactions between convection and other components of the climate system remain poorly understood and poorly simulated in global …

THE VARIABILITY OF DROUGHT DYNAMICS IN THE SOUTHWEST UNITED STATES AND AN ANALYSIS OF DROUGHT RISK IN THE NORTHEASTERN UNITED STATES
… This work used reanalysis products to compose a moisture budget analysis of the NEUS, to study both the climatology and case studies of individual drought events in the region. Our analysis showed that neither the advection of moisture into the region nor a lack of mass convergence over the …

Influence of the North Atlantic Subtropical High on Summer Precipitation over the Southeastern United States
… variability. </p><p>Analysis of regional moisture budget indicates that the variability of SE US summer precipitation is primarily controlled by moisture transport processes associated with the variation of the North Atlantic Subtropical High (NASH) western ridge, while local water …

Improving groundwater flow model parametrization techniques
… the aquifer are a major component of a flow budget during even multi-day pumping test highlighting the limitations of extrapolating pumping test results to long-term transient response without accounting for aquifer geometry and properties of the bounding units. In addition, this study …

Investigation of the positive interaction between the primary and secondary circulation and the roles of different types of precipitation in tropical cyclone formation
… in the fractional contribution by the inward moisture flux with the storm intensification implies the importance of the positive feedback among the primary circulation, the secondary circulation, and convection for tropical cyclone development. Convection near the storm center feeds off …

Aquatic macrophyte-derived biomarkers as palaeolimnological proxies on the Tibetan Plateau
… smaller (average: -86‰) at sites with a negative moisture budget. This indicates an influence of evaporation and evapotranspiration on δD of source water for aquatic and terrestrial plants. The offset between δD of mid- and long-chain n-alkanes was close to zero in most of the samples, suggesting …
