POPCICE - numerical experiments. Robert Osinski Naval Postgraduate School, Monterey rosinski@nps.edu

Coupled sea-ice ocean model Parallel Ocean Program (POP) ver. 2.01 CICE ver 3.14 beta Coupler

Control run (dyn5) Forcing data: 1979-1981 ECMWF ERA15 9-years run Ice thickness Ice extent

Dyn5 experiment results 1983 year means 1980 year atmospheric data Distribution of ice thickness is not correct Thin ice in the Central Arctic during summer period

S1 numerical experiment Start at march 1979 9 month January atmospheric forcing 1980 year results

Ice thickness at the selected section crossing the North Pole. 01st of August 1980 10th of August 1980 20th of August 1980 30th of August 1980

Bottom and top ice melt. S1 experiment

Ice-ocean heat flux. S1 experiment

Divergence of ice velocity

Wind field and ice thickness distribution. Dyn5 experiment. Cyclonic wind circulation

Wind divergence.

Plan for the next few months Test again the POPCICE Smoothing or filtering the wind fields Run with ERA40 data Some new numerical experiments Thank you!
