Abstract Decadal climate predictions provide an opportunity to anticipate climate variability over the coming years, with potential applications for the renewable energy sector. This seminar presents the work developed during my PhD on improving and exploiting decadal climate information for renewable energy applications in Europe. I will first introduce statistical downscaling approaches to improve the regional information provided by decadal prediction systems. I will then assess their predictive skill for wind, solar and compound energy indicators and investigate the added value of initialization compared with non-initialized climate simulations. Finally, I will present ongoing work combining observations, decadal predictions and climate projections to constrain future climate trajectories and provide surface wind information beyond the conventional decadal prediction horizon. Speaker information My name is Sara Moreno Montes, and I am a PhD candidate at the Barcelona Supercomputing Center (BSC). I am originally from a small city in Catalonia and hold a BSc in Physics and an MSc in Meteorology, both from the University of Barcelona. Before starting my PhD, I worked for two years as a programmer at a private company in Barcelona. After completing my Master's thesis at BSC, I decided to continue there as a PhD candidate. I am currently part of the Climate Services team, and my research focuses on the application of decadal climate predictions to the renewable energy sector in Europe. _________________________________________________________________________________________ Zoom link: https://uib.zoom.us/j/68304284910?pwd=2IgsDMWHuJlQw3XFHSTo3OoGBsRrhz.1 Meeting ID: 683 0428 4910

Abstract We examine the factors influencing the future of dissolved oxygen concentrations and future calcium carbonate (CaCO3) dissolution (CCD) rates. On the first topic, the importance of ocean oxygen to marine and terrestrial life is well-known, but ocean oxygen can be used for purposes other than breathing. Dissolved oxygen concentrations in the global ocean reflect changes in both physical and biogeochemical ocean processes. We present experiments that highlight the importance of remineralization in the oxygen budget and of ocean mixing in deoxygenation under a climate change scenario. We supplement these simulations with ones that make use of an adjoint-based general circulation ocean model. We show evidence that ocean oxygen provides information about ocean mixing. On the second topic, CaCO3 is known to dissolve throughout various portions of the water column, but little is known about how this will change in the future. Changes in ocean salinity, alkalinity, and mean age are most important in setting future CCD rates when a diagnostic approach is used. The most extreme future CCD rates are not uniformly determined by which future climate scenario is followed. However, on a global scale, results suggest that the ocean may buffer less against acidification if any of the geoengineering scenarios considered here are implemented than if our future emissions follow the most fossil fuel-intensive scenario. Speaker information Dr. David Trossman, by training, is a physical oceanographer but, by example, encourages earth system scientists to cross traditional disciplinary boundaries more often. David received his PhD at the University of Washington in Seattle in 2011 and eventually moved to Liverpool where he is now a Senior Research Scientist with the National Oceanography Centre. David uses numerical and statistical models as well as theory to improve existing or explore alternative observational methods to monitor basic ocean state variables, better understand ocean processes, and enhance ocean forecasting systems.
