I started the project on 8 March 2011. The following week, I headed to the European Wind Energy Association annual event in Brussels to present results from my PhD and some recent work on the analysis and modelling of large wind fluctuations and open cellular convection events over the North Sea.
In May 2011, I attended the European Wind Energy Association Wind Resource Assessment Technology Workshop, where I gave an invited talk presentation about wind variability offshore and its impacts on power production (download presentation). I enjoyed the chance to meet many people from research and industry, and to discuss some of the challenges of numerical modelling in a wind energy context.
In the first part of the project, I used observational and model data to explore the cross-spectral properties of wind fluctuations over the North Sea and the Baltic Sea. The cross-spectral information is an important input into power systems models for wind energy, because it characterises the correlations between wind speed fluctuations at neighbouring wind farms sites for a range of frequencies. Two papers about this work were published in 2012 (publications).
I am currently working with the representation of temporal variability in the Weather Research and Forecasting model with respect to model set-up, model initialisation and spin-up time. I am developing metrics to express the degree of temporal variability over large spatial areas such as the North Sea and the Baltic Sea.
I have also been investigating the impact of changes in surface roughness on the spatial variability of the near surface wind. This is of critical interest both for understanding the relationship between the effective 'mesoscale roughness' in the model and the impact on the resulting wind profiles, and for the correct treatment of mesoscale model output for wind energy resource mapping.
A new aspect to the project is the consideration of wind energy resource mapping in Southern Greenland. I have been working with a colleague to investigate the possibilities of modelling the mesoscale wind over the complex topography in Southern Greenland, with particular attention to the thermal flows that dominate the wind field there.
In April 2013, I attended the European Geosciences Union conference, where I presented work about the response of mesoscale models to changes in surface roughness, and co-authored a poster presentation about mesoscale modelling in South Greenland.
In April 2013, I gave a 1 hour presentation about wind energy research at a course for gymnasium teachers at Roskilde University. This forms part of the 'popular dissemination' activities of my post-doc project.
In June 2013, a colleague presented a poster about our work on the spectral response of mesoscale model output to changes in surface roughness at the WRF User's workshop in Boulder, USA. (publications).
In December 2013, I gave a seminar to the Maths and Physics faculty at Roskilde University about mesoscale modelling and wind energy. This forms part of the 'dissemination' activities of my post-doc project.
