MELTING INFLUENCES ON THE COMPUTER FORECAST OF WIND DRIFT AND CONCENTRATION OF SEA ICE.
NAVAL POSTGRADUATE SCHOOL MONTEREY CA
A computer program to provide five-day forecasts of the wind drift and concentration of sea-ice has been developed however, one of the problems not considered is the effect of melting. Melting influences concentration in two ways it reduces the amount of ice directly, and changes in thickness and concentration change the wind drift. A model to describe how ice-melt decreases thickness and concentration is developed and programmed. The results are used to modify the input data in the wind drift forecast forecasts are compared with those based on wind drift alone. The modification enhances the use of the program as a forecast tool with the addition of normally available data. Author
