Wind Drift of Sea Ice: A Supplement to the Naval Oceanographic Office Numerical Ice Forecasting System.

The numerical ice prediction system described in RP 8 has been in use since 1971. Its outputs, however, have been related only to ice growth not ice drift. In addition the system now provides an output of daily ice drift at 62 arctic stations. Drift is calculated as a function of wind stress, water...

Description
Summary:The numerical ice prediction system described in RP 8 has been in use since 1971. Its outputs, however, have been related only to ice growth not ice drift. In addition the system now provides an output of daily ice drift at 62 arctic stations. Drift is calculated as a function of wind stress, water stress, and Coriolis force. The computer output is sufficiently accurate for ice drift in the locality of the station whose wind observations were input to the model. However, more recent research indicates that for greater accuracy and for computations of divergence and convergence interaction between floes must be considered.
