Spatial Optimal Interpolation of Aquarius Sea Surface Salinity: Algorithms and Implementation in the North Atlantic
Publisher: American Meteorological Society
Abstract: method is presented for mapping sea surface salinity (SSS) from Aquarius level-2 along-track data in order to improve the utility of the SSS fields at short length [O(150 km)] and time [O(1 week)] scales. The method is ...
Fall–Winter Current Reversals on the Texas–Louisiana Continental Shelf
Publisher: American Meteorological Society
Abstract: Fall?winter recurrence of current reversal from westward to eastward is identified on the Texas?Louisiana continental shelf using the current-meter [Texas?Louisiana Shelf Physical Oceanography Program (LATEX-A)] and ...
Analysis of Sparse and Noisy Ocean Current Data Using Flow Decomposition. Part II: Applications to Eulerian and Lagrangian Data
Publisher: American Meteorological Society
Abstract: The capability of the reconstruction scheme developed in Part I is demonstrated here through three practical applications. First, the nonlinear regression model is used to reproduce the upper-layer three-dimensional ...
Analysis of Sparse and Noisy Ocean Current Data Using Flow Decomposition. Part I: Theory
Publisher: American Meteorological Society
Abstract: A new approach is developed to reconstruct a three-dimensional incompressible flow from noisy data in an open domain using a two-scalar (toroidal and poloidal) spectral representation. The results are presented in two ...
Probabilistic Stability of an Atmospheric Model to Various Amplitude Perturbations
Publisher: American Meteorological Society
Abstract: Every forecast should include an estimate of its likely accuracy, as a measure of predictability. A new measure, the first passage time (FPT), which is defined as the time period when the model error first exceeds a ...
Linear Wind-Forced Beta Plumes with Application to the Hawaiian Lee Countercurrent
Publisher: American Meteorological Society
Abstract: wo numerical ocean models are used to study the baroclinic response to forcing by localized wind stress curl (i.e., a wind-forced ? plume, which is a circulation cell developing to the west of the source region and composed ...
Mean Dynamic Topography of the Ocean Derived from Satellite and Drifting Buoy Data Using Three Different Techniques
Publisher: American Meteorological Society
Abstract: Presented here are three mean dynamic topography maps derived with different methodologies. The first method combines sea level observed by the high-accuracy satellite radar altimetry with the geoid model of the Gravity ...
