On the decrease of Arctic sea ice volume

The decrease of Arctic sea ice volume is investigated using a dynamic-thermodynamic sea ice model. The model was forced with NCEP/NCAR reanalysis winds and surface air temperatures in a hindcast simulation of the period 1958–1998. The simulation reveals pronounced decadal variability (10–12 years) a...
