  • Atmospheric boundary layer coupling to midlatitude mesoscale sea surface temperature anomalies

    Creator:
    Thum, Nicolai
    Abstract:
    This thesis examines the mechanisms that couple the monthly-averaged atmospheric boundary layer (ABL) to open-ocean sea surface temperature (SST) perturbations on scales of 50-500 km. The observed positive correlation between surface wind speed anomalies and SST anomalies is successfully simulated using the Weather Research and Forecasting (WRF) model. In numerical...

  • Surface wind modification near mid-latitude ocean fronts : observational and dynamical analysis

    Creator:
    O'Neill, Larry W.
    Abstract:
    Interactions between surface winds and meanders in mid-latitude sea surface temperature (SST) fronts with horizontal length scales of 100-1000 km are investigated from satellite observations and numerical simulations. Observations from the Sea- Winds scatterometer on the QuikSCAT satellite show that the magnitude, direction, curl, and divergence of the surface wind...

  • Measurement and modeling the physical controls of snowmelt in the Pacific Northwest

    Creator:
    Mazurkiewicz, Adam B.
    Abstract:
    The physical controls of snowmelt in the Pacific Northwest (PNW) are poorly understood. While there have been numerous field and modeling investigations at the plot and watershed scale, few studies have identified how the snow energy balance (EB) components vary in importance both spatially and temporally. The identification of how...
