A series of numerical experiments with a three-dimensional, baroclinic model were conducted to study the influences of density stratification and wind-driven currents on the K1 tide over the continent...
The Effect of the Seasonal Variation of Stratification on the Circulation of the Northern Gulf of California
Effect Seasonal Variation Northern Gulf California
2008/6/4
Direct current measurements reveal that the circulation of the northern Gulf of California in the annual timescale consists of a cyclonic basinwide gyre (0.35 m s−1) that lasts from June to Sept...
The Role of Eddy Transfer in Setting the Stratification and Transport of a Circumpolar Current
Eddy Transfer Stratification Transport Circumpolar Current
2008/5/26
High resolution numerical experiments of a circumpolar current are diagnosed to study how lateral and vertical transfer of buoyancy by geostrophic eddies balances advection by a meridional circulation...
A simple theory is presented for the buoyancy anomaly and depth of penetration of a warm lens created by a surface buoyancy flux and Ekman pumping in an initially homogeneous, rotating fluid. It is as...
Physical pathways of nutrient supply in a small, ultraoligotrophic arctic lake during summer stratification
Physical pathways nutrient supply
2014/5/4
During the ice-free period in the Arctic, the thermal structure and mixing dynamics of small lakes change with the passing of air masses. In Toolik Lake, Alaska, stable warm air masses during the ice-...
