Ice drift in the marginal ice zone (MIZ) is a very important feature of air-ice-ocean interaction at high latitude. Thermally generated surface winds, blowing from ice to water (ice breeze) with some deflection due to the eart.h rotation, force the ice drift and ocean currents near the MIZ. By changing the surface temperature Cilradient, the ice motion and the ocean currents feed back on the su...

Abstract Urban heat island (UHI) and sea–land-breeze systems are well-known important characteristics of the climate coastal cities. To model these, accurate estimation surface energy balance (SEB) is a key factor needed to improve local-scale simulations thermodynamic dynamic boundary circulations. The Weather Research Forecasting Model with single-layer urban canopy (WRF/SLUCM), parameters de...

Despite being the largest High Nitrate Low Chlorophyll (HNLC) region, the Southern Ocean sustains phytoplankton blooms through the summer, when presumably there is sufficient light, but nutrients in the euphotic zone have been depleted. Physical processes that can potentially supply nutrients from subsurface waters to the euphotic zone, and promote phytoplankton growth in the summer, have not b...

Local thermal flows may be organized where there is a local horizontal pressure gradient due to differential surface heating or cooling. According to a simple conceptual model of katabatic flows (e.g. Egger 1990), they develop in sloping topography where the air at the surface cools relative to the air aloft, e.g. due to radiative cooling on clear nights. The cold and heavy air flows downslope ...

The Fresh Breeze program execution model was designed for easy, reliable and massively scalable parallel performance. The model achieves these goals by combining a radical memory model with efficient fine-grain parallelsim and managing both in hardware. This presents a unique opportunity for studying program execution in a system whose memory behavior is not well understood. In this thesis, I s...
