New Research paper

Co-occurring wintertime flooding and extreme wind over Europe, from daily to seasonal timescales

  • Champion, A.,
  • Griffin, A.,
  • A.L.Kay, A.,
  • Kumar, D.,
  • Panosi, F.,
  • Bloomfield, H.,
  • J.Hillier, J.,
  • Shaffrey, L.,
  • Bates, P.,
  • R.James, R.

Why and when do floods and extreme wind occur together? Will climate change make this happen more frequently? This research sets out to understand the correlations between flood and wind extremes and the impact they have on risk.
