This project has three specific goals:

  1. Conduct a study of the Arctic atmosphere that uses observations, modeling and theoretical interpretation to document 3-D structure and evolution of the Arctic vortex and anticyclones with emphasis on vortex-vortex interactions and stratospheric warming/mesospheric cooling events during the IPY;
  2. Determine our ability to forecast synoptic-scale weather events in the troposphere based on observations and analyses of the mesosphere and stratosphere; and
  3. Study the coupling between anomalous stratospheric weather and tropospheric annular modes during the IPY.
