Example of commercial usersExample of commercial users
• OCENS (www.ocens.com) is a Seattle, Washington company delivering weather and ocean data to at-sea users around the world.
• METEOREM (www.meteorem.com) provides ocean and weather forecasts to marinas, fishing fleets, etc.
• ROFFS (www.roffs.com) consist of fisheries oceanographers that use satellite and other oceanographic and meteorological data
• Horizon Marine, Inc. (www.horizonmarine.com)• Orbimage (www.orbimage.com)• Shell (www.shell.com)• Exxon-Mobil (www.exxonmobil.com)• Ocean Numerics (www.oceannumerics.com)• Etc.

• TAKE AN REPRESENTATIVE IMAGE• TRACE THE WATER MASS
BOUNDARIES• COMPARE TO PREVIOUS DAY• COMPARE TO TWO DAYS AGO …..
– TIME HISTORY OVER GOOD BOTTOM• GRADIENT STRENGTH• VELOCITY OF WATER• OTHER CIRCULATION FACTORS
– LOCAL & REGIONAL– PERSISTENCE & CLIMATOLOGY
– LOCAL & REGIONAL WINDS
CLOUDS ARE CLOUDS ARE A MAJOR PROBLEMA MAJOR PROBLEM
• SST and OCEAN COLOR NOT ALWAYS AVAILABLE
• USE ALTIMETERS– VALID DATA TWICE A WEEK– VISUALIZATION OF FRONTAL
BOUNDARIES A PROBLEM
• USE HYCOM PRESENTLY FOR GUIDANCE NOT FOR DETAILS– VALIDATION NEEDED -> TRUST

– Very important - must resolve the inner core of the storm– Start with the 0.5-degree NOGAPS forcing
• Problems:– Eye and eyewall poorly resolved– Maximum winds underestimated by 30-40%
– Blend NOGAPS wind field with HWIND gridded vector wind fields from NOAA/HRD
• Produce wind speed and wind stress forcing fields that resolve the inner core structure
