Interests and Research: I am working with the Atmosphere and Land Observation group of CAWCR on remote sensing of tropical convection. The main thrust of my research is to link dual Doppler radar retrievals of updraft strength to microphysical (ice, snow, hail, wet snow, rain etc...) properties of deep tropical convection. The aim is to better understand the link between quantities used to trigger convection in numerical weather prediction products and the distribution of hydrometeors. For example: for a given measure of atmospheric instability and surface inhibition what will be the size distribution of ice particles in the upper atmosphere? This has a very large affect on the feedback increased convection would have on global warming in global climate models, which is why I gratefully recieve support from the Atmospheric Radiation Measurement Program. I am also interested in open source programming (although I am far from calling myself a programmer!) I am a Python and SciPy user and I have an interest in introducing these open source array based numerical packages into the meteorological research and teaching community.
