  1. Sea Ice 16 Sept 2009

  2. ARCTIC DIPOLE SLP in JUNE-JULY

  3. OUTLOOK 2009~ 15 Groups Participated 4 Full modeling groups 2009 AWI Model Distribution

  4. Look Beyond September!

  5. 30 Sept 2009

  6. STILL MAJOR LOSS OF MULTI-YEAR Sea Ice perennial ice (white), mixed ice (aqua), seasonal ice (teal) derived from QuikSCATscatterometer(big change from 2004)

  7. Sea Ice Age from Rigor

  8. Loss of Sea Ice Impacts Larger Atmospheric Climate Pacific Arctic 2002-2008 Fall temps Anomalies Reach upper troposphere 2002-2008 Geo Hghts Anomaly Zonal Wind (color) and 2002-2008 Anomaly 2002-2008 Fall 500-1000 mb Thickness Anomaly 700 mb zonal wind anomaly Thermal Wind Reduces Polar West Winds Tellus, in press

  9. 2009 OUTLOOK was as a success 15+ GroupsWhile 2009 was 3rd lowest summer extent, fall freeze up was very late. Multi-year sea ice very low relative to 2004 (Kwok). Arctic still behaving with extremesContinue for 2010, met the goal of rapid communicationPriority for winter 2010: Work with other groups to define priority observations in support of OUTLOOK- ocean heat content, visual recon of ice types
