Extreme dry and wet events in Iceland: Observations, simulations and scenarios
Monthly extremes of dryness and wetness in Iceland are analysed based on the standardised precipitation index (SPI). The analysis is performed for observations and four sets of coupled atmosphere-ocean climate model simulations (ECHAM5.MPI-OM) to link water cycle extremes in Iceland with regional at...
