Tim Palmer is an internationally renowned meteorologist with a particular interest in the predictability and dynamics of weather and climate. Tim pioneered the development of probabilistic prediction techniques based on ensembles of forecasts. These techniques were implemented first at the Met Office and the European Centre for Medium-Range Weather Forecasts and are now universal worldwide, allowing disaster relief agencies to act pre-emptively ahead of a possible extreme weather event.

Tim's work is theoretical as well as practical. His recent research exploits ideas in imprecise computing to develop computer simulations of weather and climate at very high resolution. His opinion is highly regarded at an international level through serving on multiple government advisory committees and he has been formally acknowledged as contributing to the Intergovernmental Panel on Climate Change's award of Nobel Peace Prize.

Tim was appointed as CBE for services to science and has won the top awards of organisations such as the American Meteorological Society, the Institute of Physics and the Royal Astronomical Society. He is an international member of a number of academies around the world, including the US National Academy of Sciences. Remarkably, he also retains an active interest in his original doctorate topic, fundamental physics.
