Evaluating the 3D EnKF - VAR Hybrid Data Assimilation in GSI for Surface and Upper Level Analyses
… has a higher accuracy in 2m temperature and 10m winds speed than the background and the 3D VAR scheme, especially in regions of weather systems such as frontal boundaries and low pressure centers. Statistical comparisons of the surface analysis indicated the hybrid scheme outperformed the …

On use of the anelastic vertical vorticity equation in dual-Doppler analyses of the vertical velocity field.
The potential for applying the anelastic vertical vorticity equation for dual-Doppler synthesis of the vertical wind field is explored. In particular, application of the vorticity equation as a weak variational constraint to retrieve the boundary condition field(s) is investigated. The …

Modeling and Simulation of Random Processes and Fields in Civil Engineering and Engineering Mechanics
This thesis covers several topics within computational modeling and simulation of problems arising in Civil Engineering and Applied Mechanics. There are two distinct parts. Part 1 covers work in modeling and analyzing heterogeneous materials using the eXtended Finite Element Method (XFEM) with …

The evolution of coastal lows along the south coast of South Africa
… by a marked change in both wind direction and speed. Occasionally, a dramatic and rapid increase in wind speed takes place, which may cause damage to property and is potentially hazardous to aviation and shipping. Current global scale numerical weather prediction models do not forecast the …
