Description
Summary:The long-term goal of this project is to examine the role of sea ice and atmospheric interactions in the retreat of the Arctic seasonal ice zone (SIZ). As sea ice retreats further, changes in lower atmospheric temperature, humidity, winds, and clouds are likely to result from changed sea ice concentrations and ocean temperatures. These changes in turn will affect the evolution of the SIZ. An appropriate representation of this feedback loop in models is critical if we want to advance prediction skill in the SIZ. To achieve our goals we will conduct a combination of targeted measurements and modeling experiments as part of the atmospheric component of the Seasonal Ice Zone Reconnaissance Survey project (SIZRS). We will * Determine the role of changing atmospheric properties in modifying the evolution of the SIZ in the Beaufort and Chukchi Seas from spring through fall. * Determine how changes in sea ice and sea surface conditions in the SIZ affect changes in cloud properties and cover. * Determine the role additional atmospheric profile observations may play in improving the quality of weather forecasts and ice predictions for the SIZ of the Beaufort and Chukchi Seas. * Adapt a low cost, expendable, air-deployed micro-aircraft to obtain temperature and humidity profiles and cloud top and base heights Prepared in cooperation with Department of Aerospace Engineering, University of Colorado, Boulder, CO.
