👨🏻‍💻 I’m a researcher working on the near-surface wind speed change at Regional Climate Group (RCG) in University Gothenburg.

🔬 My research interests are wind speed change and wind energy, my work aims to find the potential causes to changes in wind speed and wind extreme events, using a combination of observationas, reanalysis and simulation models.

📽️ Collaborations are welcome.

Climate change impacts on wind power generation

Less wind has a direct impact on the amount of electricity that can be generated by the many wind farms at globe. If the global stilling continues to happen will have a massive impact on alternative energy production. Turbines are somewhat inefficient, with limits on how much energy they can extract from the wind. According to some research, a 10 percent decline in wind speeds would actually result in “a 30 percent drop, and that would be catastrophic.”

Increases of offshore wind potential in a warming world

Offshore wind farms, a rapidly expanding sector within wind energy, are playing a significant role in achieving global carbon neutrality, and this trend is to continue. Here, we utilize ERA5 reanalysis to correct offshore wind speed trends predicted by CMIP6 models. This approach led to enhanced projections for changes in offshore Wind Power Density (WPD) under four Shared Socioeconomic Pathways (SSPs) scenarios. Throughout the 21st century, global offshore WPD is projected to follow an upward trend across all SSP scenarios. Notably, Europe stands out with the most substantial increase in offshore WPD among regions with higher current installations, projected to reach up to 26% under 4°C global warming. Our study uncovers a notable increase of global offshore WPD in a warmer climate, which offers valuable insights for the strategic planning of future global wind energy. This research is featured in The Guardian, AGU News and the University of Gothenburg.

Eastern Asian Subtropical Jet contributed to the hiatus of March surface wind over China

A general decrease (stilling) that ceased around 2011, followed by a general significant increasing tendency (reversal) in all months but March over China. Indeed, March’s wind series after 2011 showed a pause (i.e., hiatus) from the 1979–2011 slowdown. This hiatus was mainly caused by the general wind reduction across northern China since 2011, which differs from the wind increase observed in other regions. The slowdown in March from 2011 to 2020 is related to the southward shift of East Asian subtropical jet streams, which are fast‐flowing, narrow, and meandering air currents in the upper atmosphere (a). Jet streams play an important role in shaping both upper and lower air circulation and influence surface wind by transporting high and low‐pressure systems.
