Tim Palmer

Palmer’s research has focussed on the nonlinear predictability and dynamics of the climate system. He co-discovered the world's largest breaking waves, and proposed a nonlinear framework for the regional manifestation of climate change, based on the nonlinear dynamics of quasi-stationary weather regimes. He was amongst the first to propose the importance of developing unified or "seamless" weather and climate prediction models. As of 2016 Palmer's research is focussed on the development of stochastic parametrisations in weather and climate simulators, and the application of inexact computing techniques for developing ultra-high resolution climate models. Palmer believes strongly that human and computing resources must be pooled internationally to develop reliable climate prediction systems. He remains active in the area of fundamental physics, promoting the synergistic "Cosmological Invariant Set Postulate" as a primitive geometric principle for physics of the large and small.

After a chance meeting with geophysicist Raymond Hide, he became interested in climate and was employed by the Met Office – including a year at the University of Washington. In 1986 he joined the European Centre for Medium-Range Weather Forecasts where he led the newly formed Predictability and Diagnostics Division, where he led the development of the ECMWF medium-range ensemble prediction system and the European DEMETER multi-model ensemble seasonal climate prediction system . In 2010 Palmer became a Professor of Climate Physics at the University of Oxford, being one of the "2010 Anniversary" Royal Society Research Professors, created to celebrate the Royal Society's 350th Anniversary. At Oxford, Palmer is additionally co-director of the Oxford Martin Programme on Modelling and Predicting Climate and is a professorial fellow at Jesus College, Oxford.

Palmer was elected a Fellow of the Royal Society (FRS) in 2003, and was appointed Commander of the Order of the British Empire (CBE) in the 2015 New Year Honours for services to science. Other awards include:

Timothy Noel Palmer CBE FRS (born 31 December 1952) is a mathematical physicist by training. He has spent most of his career working on the dynamics and predictability of weather and climate. Amongst various research achievements, he pioneered the development of probabilistic ensemble forecasting techniques for weather and climate prediction (at the Met Office and the European Centre for Medium-Range Weather Forecasts). These techniques are now standard in operational weather and climate prediction around the world, and are central for reliable decision making for many commercial and humanitarian applications.
