My Research: http://www.met.reading.ac.uk/~ys906449

Research Interests:

  • Convective initiation and storm morphology
  • Numerical modelling of convection
  • Dual polarisation radar
  • Ice and rain microphysics and processes

Research Projects:

  • Weather and Climate Science for Service Partnership (WCSSP) South Africa Project: This project will focus on the physical representation of convective storms over southern Africa to demonstrate the benefits of increases in model resolution. In addition, the impact of changes in the microphysics parameterisation on convective storm characteristics will be investigated. This will be achieved by comparing Met Office Unified Model output with radar observations from the South African Weather Service (SAWS) weather radar network, which has recently been upgraded to S-band. This will include a statistical analysis of storm size, frequency, intensity and duration, as well analyses for specific case studies. Ultimately, this will be used to create a diagnostic toolbox to evaluate convective scale models over southern Africa.
