Joan Llort Jordi (IMAS) Farewell Seminar: Decadal changes in Tasman Sea phytoplankton induced by atmospheric dust
Speaker: Anna von der Heydt (Utrecht University) Climate sensitivity is a key predictor of climate change. However, it is not very well constrained, either by climate models, observational, historical or palaeoclimate data. This 'uncertainty' has its origin in different aspects: i) There is a classical uncertainty related to measurements or proxy estimates of temperature and... View Article
Zaved Khan (Bureau of Meteorology). Modelling seasonal rainfall forecasts forced with improved predictive ocean surface temperature Seasonal rainfall forecasts are in high demand for users such as irrigators and water managers in decision making and risk management. Both statistical and dynamical models are widely used to generate probabilistic rainfall forecasts in advance for a season.... View Article
Penny Maher (University of Utrecht) The tropics are expanding poleward at about 1 degree per decade in observations. The Hadley cell edge is one common measure of tropical expansion. One alternative method is the trend in the subtropical jet position. Unlike the Hadley cell edge, the observed trends in the subtropical jet position are much... View Article
Prof Christian Jakob (Monash University). Climate models have significant errors in precipitation globally, but in particular in the tropics. Most models overestimate annual mean tropical precipitation, with the largest errors occurring over the warm tropical oceans of the Western Pacific, Indian Ocean and Atlantic. In addition to the mean errors, there are significant shortcomings in... View Article

During the last 70 years, solving physical equations on High Performance Computers has been the main workhorse of weather, climate and environmental research and prediction. It has been a fantastic ride, substantially improving our understanding and boosting our forecasting capabilities. However, Moore's law is over, the energy cost of HPC is hardly affordable, and increasing... View Article
