1. Produce a geospatial surface meteorological database for the Beaufort and Chukchi Seas and the adjacent coastal areas by collecting available conventional and unconventional surface and atmospheric data and conducting field work; 2. Establish a well-tuned Beaufort/Chukchi seas mesoscale meteorology model through further modeling studies for the optimization and improvement of the model physics and configuration; 3. Conduct a long-term hindcast simulation with the optimized data-modeling system and produce a high resolution meteorological dataset for the Beaufort and Chukchi regions; and 4. Document the high-resolution climatological features of the Beaufort/Chukchi seas’ surface winds, including an analysis of the interannual variability and long-term
