Biography
Alan Gadian is a senior scientist at the UK National Centre for Atmospheric Sciences (NCAS) and is currently based at the University of Leeds. Since completing his PhD in Meteorology at Imperial College, he has spent the last 30 years researching into the dynamics of the atmosphere, cloud microphysics and numerical methods in Numericl Weather Prediction and Climate Models. For the past few years he has been working on Marine Cloud Brightening (MCB), from the theoretical and computational viewpoint. In recent years he has been editor in chief of the Royal Meteorological Society Journal, Atmospheric Science Letters and external examiner for the University of East Anglia undergraduate course in Meteorology and Atmospheric Sciences. He collaborates with scientists from NCAR and Europe. He is now working on the WISER project (Weather Impact Studies at Extreme Resolution), gravity wave propagation generated by South Georgia, and development of new models on meteorology
Abstract
Computational and Network Challenges for Weather Modelling
Weather and Climate Modelling world-wide is a significant user of computational resources.
Not only do Numerical Weather Prediction Models (NWP) require vast numbers of FLOPS, as scientist try to increase the number of grid points (i.e. resolution and hence accuracy of the modelling), but also large amounts of internal data transfer and storage. FLOPS are free is the current mantra in the NWP world.
This talk will illustrate the challenges for one such project, WISER (Weather climate change Impact Study at Extreme Resolution) and how important data transfer and manipulation has become. The issues facing the Next Generation Weather and Climate codes will be illustrated by reference to current developments in the UK (Gungho project) and other codes (e.g. US MPAS project )which take advantage of massively parallel computers.
