Spontaneous tropical cyclogenesis in a cloud revolving numerical model
… convective aggregation creates regions of high moist static energy, and regions of cold dry air. Importantly, a deep moist column is created which provides a perfect environment the developing storm. In the second step, mid-level cyclone intensification, a mid-level cold core cyclone develops in …

Spatial characteristics of the remotely-sensed surface urban heat island in Baton Rouge, LA: 1988-2003
… from known NDVI values. Finally, the moist static energy parameter was evaluated to test for a better indicator of the UHI over time throughout the study area. A decreasing temporal trend in MSE was identified throughout the study period (1988 - 2003) whereas no significant linear …

Land Cover Change and its Impacts on a Flash Flood-Producing Rain Event in Eastern Kentucky
… LCC also modified various surface fluxes, moist static energy, planetary boundary layer height, and local-scale circulation wind circulation. The key findings were the modification in fluxes and precipitation totals. With respect to sensible heat flux (H), there was an increase to bare soil …

The Madden-Julian oscillation and nonlinear moisture modes
… thesis hypothesizes that the MJO is a nonlinear moisture mode whose existence depends on moisture-convection feedback (the feedback between deep convection and environmental free-tropospheric humidity), and that weak moisture convection feedback in general circulation models accounts for their …

Understanding the Characteristics of Precipitation and Their Response to Climate Change
… a negative contribution from an increase in dry static stability. In the moist decomposition, changes in moist static stability play a key role. Second, I look at the power-law frequency distributions and fractal dimensions of tropical precipitation clusters. I propose a viewpoint that regards …

Biosphere-atmosphere interactions over semi-arid regions : modeling the role of mineral aerosols and irrigation in the regional climate system
… dust, a shallower boundary layer redistributes moisture closer to the surface thus offsetting negative temperature effects on the boundary layer moist static energy. With irrigation, a large reduction of the boundary layer height results in less triggering of convective activity and hence …

On the nature of the atmospheric cloud radiative effect and its impact on tropical convection
… high clouds have been shown to converge radiant energy within the atmosphere. We term this phenomenon the Atmospheric Cloud Radiative Effect (ACRE). The addition of energy unequally in space and time has profound effects on tropical convection. In this thesis, we show that the extra heating by …

Physical mechanisms controlling self-aggregation of convection in idealized numerical modeling simulations
… role in modulating radiative cooling and the moisture distribution underlines the importance of understanding how and why tropical convection organizes. In this work, the fundamental mechanism underlying the self-aggregation of convection is explored using a cloud resolving model. The …

South Asian summer monsoon variability: a modelling study with the atmospheric regional climate model HIRHAM5
… order to satisfy the rapidly rising demand for energy, is highly reliant on the prevailing meteorology. The major drought years 2002 and 2009 for the Indian summer monsoon during the last decades, which are results of the occurrence of multiple extended breaks, emphasise exemplary that the …

The Hydroclimate Variability of Central Africa: seasonal cycle, mechanisms, teleconnections and impacts on neighbouring regions
… leading Central Africa to become a source of moisture. During this season, both surrounding oceans are suppliers of moisture, with some additional contribution from the Congo basin rainforest. Central Africa rainfall variability is controlled by large-scale circulation variation, rather than …
