Land surface and orographic controls on precipitation patterns in the Sierra Madre Occidental and Western Ghats
Several aspects of land surface-atmosphere interactions cannot be adequately captured by climate models, due in part to inadequacies in representing small scale processes in space and time, such as diurnal cycles, convection, and cloud microphysics. Individual and collaborative efforts using …

The influence of horizontal resolution and boundary forcing in simulating hurricanes over the South Atlantic Ocean using WRF
… (SAO). Hurricanes rarely form over this region and as such these communities are not prepared for them. Previous studies have suggested that anthropogenic warming may lead to more frequent hurricanes over the region and have demonstrated the capability of the Weather Research and Forecasting …

Using land cover changes to mitigate the impacts of hot temperatures in South African cities
… severe impacts on human health. Climate change and population growth are expected to exacerbate these impacts in the future, given that Southern Africa has been projected as a hotspot for future warming and growth. The added socio-economic factors leave a large proportion of South Africa's …

Dynamics of cloud-top generating cells in winter cyclones
… cells (GCs) are ubiquitous in the warm-frontal and comma-head regions of midlatitude winter cyclones. The presence of fall streaks emanating from the GCs, and their persistence either to the surface or until merging into precipitation bands suggests that GCs are a critical component of the …

Toward assessing the effects of aerosols on deep convection: a numerical study using the WRF-Chemistry model
… important role in the development of clouds and precipitation. Few meteorological models have been developed or adapted to simulate aerosols and their contribution to cloud and precipitation processes. The Weather Research and Forecasting model (WRF) has recently been coupled with an …

Characteristics of precipitation and extreme precipitation events over the Drakensberg Mountain range in past and future climates
… activities in Lesotho, South Africa, and Namibia. Meanwhile, extreme precipitation events over the Drakensberg are a threat to the communities around the mountains. While several studies have shown that mountains are among the most sensitive regions to climate variability and change, …

WRF-based dynamical downscaling over High Mountain Asia
… area including the Tibetan Plateau (TP) and surrounding mountain ranges. Due to its unique climatic and tectonic settings, the HMA region is highly vulnerable to natural hazards, such as landslides and Glacial Lake Outburst Floods (GLOFs). Under climate change, the frequency of natural …

A numerical study of surface air temperature response to vertical mixing and momentum extraction by wind farms and the impacts of wind farms on mesoscale boundaries
… In this thesis, a high resolution numerical model is employed to explore the response of land surface and near surface air temperatures within and in the immediate vicinity of large wind farms in west central Texas to changes in the turbines’ thrust and TKE coefficients during meteorological …

North American monsoon precipitation and its precursors: processes at the seasonal and diurnal scale
The Weather Research and Forecasting (WRF) model was run at 100~km, 25~km, and 10~km resolution for the 2000 and 2004 monsoon seasons (July-September), a dry year and a wet year. These years were chosen to represent contrasting precipitation outcomes to assure that results were robust across …
