“Assessment of weather forecast performance with respect to weather regimes for better meteorological guidance in energy trading”
Dra. Masirol Osman – Karlsruhe Institute of Technology
Weather forecasts are an important driver of the European energy market. Decarbonization increases and changes the exposure of energy system to climate and therefore markets are particularly sensitive on changes in the predicted predominant large-scale flow situation over entire Europe. At the interface of medium and sub-seasonal range such large-scale weather conditions can be depicted by so-called weather regimes. Weather regimes are quasi-stationary, persistent, and recurrent large-scale flow patterns that affect the weather conditions on the scale of a continent and typically last 5-20 days. Besides the modulation of surface weather, weather regimes are also tied to periods of extreme weather such as heat waves and droughts, cold spells, or anomalously windy conditions. Forecasts for weather regimes are thus of high interest for assessing the weather evolution a few weeks up to a month ahead in particular in socio-economic sectors such as the energy industry, agriculture, or tourism. In this talk we will show some preliminary results of the joint project between the Large Scale and Predictability Group at KIT and AXPO solutions, an energy trader company. This project aims at providing a systematic assessment of NWP model performance for weather regime forecasts in the European region on medium-range to sub-seasonal time scales with focus on regime onsets or transitions which modulate surface weather in a way that is particularly relevant for the European energy system.
