Abstract:

LONG-TERM PROJECT GOALS. This project seeks to describe how heterogeneous surface fluxes that control ice growth are coupled to the atmosphere through radiative and sensible heat processes. Our hypothesis is that spatial and temporal variations in different air masses account for much of the climate variability that occurs in the Arctic. OBJECTIVES. 1 We will combine AVHRR temperature estimates, surface temperature and radiation data from an array of drifting buoys, and vertical temperature and cloud data to estimate aggregate scale 100 km x 100 km radiative and sensible heat fluxes for selected periods throughout the cold season Tair 0 deg, October through May during SHEBA. 2 We will assemble and evaluate information necessary to estimate lateral heat advection over the SHEBA region from gridded atmospheric data fields from the National Centers for Environmental Prediction NCEP and the European Center for Medium-Range Weather Forecasting ECMWF. These gridded fields will be modified by data from the surface array and SHEBA core measurement program as necessary.
