Department of Meteorology Current PhD Students Annual Prize Winners 2018.
This South-East local centre meeting will be a showcase of PhD research in the Department of Meteorology, University of Reading.
Programme
Bethan Harris - Available Potential Energy and Tropical Cyclone Intensification
The past few decades have seen great improvement in the forecasting of the tracks of tropical cyclones, but a relatively slow improvement in intensity forecasts. It is important to fully understand the processes involved in intensification in order to accurately predict events such as rapid intensification, which can threaten lives and property.
Our work looks at a theory of atmospheric energy (Available Potential Energy density, or APE density), which has not previously been applied to tropical cyclones. We use a simple numerical model of a tropical cyclone to investigate the sources and sinks of APE density in an intensifying tropical cyclone, to establish the relative importance of different processes to intensification.
Will McIntyre - Modelling Convection with Conditional Averaging
Shallow and deep convection have historically been statistically parameterized as they occur in far smaller horizontal scales relative to the resolutions of weather prediction models. Modern resolutions are too high to make some large-scale statistical assumptions and too coarse to model the convection outright meaning we currently find ourselves in the "grey zone" of convection modelling. A technique known as conditional averaging offers an alternative approach to model convection in the grey zone by treating the convection as a separate fluid which interacts with the remainder of the environment. However, the new approach means that more equations must be numerically solved compared to existing models, presenting additional challenges in producing a stable and accurate numerical scheme.
