Summary: | Procedures are detailed for preparing 15- and 30-day forecasts of ice edge movement, ice growth, and ice disintegration at Alaskan and other coastal and offshore sites using current ice and prognostic environmental data. A statistical method for forecasting ice edge movement and ice distribution changes is given in this guide since this method has proven most useful and has yielded the best results. Frost degree day, related ice growth, and estimated ice disintegration curves are included for 14 stations. Background data on environmental factors related to growth, drift, and disintegration of sea ice throughout the Alaskan area include 15-day mean, median, and extreme southern and northern positions of the pack ice edge and ranges of the 15-day means covering the 17-year period from 1954 through 1970 for semimonthly periods. |
