Workshop #11, October 25-27, 2006

Woods Hole Oceanographic Institution, Woods Hole, Massachusetts

Framework Topics

The major goal of the 11th AOMIP workshop is to review its activities and findings for the last 5 years and to plan its major activities for the next 5-year period.

The major workshop themes include modeling problems and results of:

  • Sea ice dynamics and thermodynamics;
  • Water circulation with a focus on Atlantic and Pacific waters;
  • Modeling of freshwater and heat content variability;
  • Modeling of sea level variability.

Other topics to be discussed are:

  • How to validate and calibrate models;
  • How and where to improve models;
  • Interactions and collaborations with global modeling teams and other MIPs;
  • AOMIP major results and future studies.
