Isopycnal EOFs in the Azores Current Region: A Statistical Tool forDynamical Analysis and Data Assimilation
Publisher: American Meteorological Society
Abstract: An empirical orthogonal function analysis of the vertical space?time variability of the thermohaline structure of the ocean in summer and fall 1993 in the Azores Current region has been performed. The analysis used data ...
Assimilation of Altimeter Eddy Fields in a Limited-Area Quasi-Geostrophic Model
Publisher: American Meteorological Society
Abstract: Techniques for the synoptic analysis, vertical inference, dynamical adjustment, and forecast of altimetric and deeper in situ data are presented as a first step towards the design of continuous assimilation schemes in ...
Horizontal and Vertical Structure of the Representer Functions for Sea Surface Measurements in a Coastal Circulation Model
Publisher: American Meteorological Society
Abstract: The representer functions used to propagate the information from observations onto model variables in a sequential data assimilation scheme are calculated with a statistical method. The Princeton Ocean Model is used in a ...
Contribution of a Wide-Swath Altimeter in a Shelf Seas Assimilation System: Impact of the Satellite Roll Errors
Publisher: American Meteorological Society
Abstract: The authors investigate the potential qualitative improvement brought by wide-swath, interferometry-based ocean altimetry measurements with respect to classical nadir altimeters in a coastal/shelf data assimilation system. ...
Observation of Long Equatorial Waves in the Pacific Ocean by Seasat Altimetry
Publisher: American Meteorological Society
Abstract: Synoptic maps of the mesoscale dynamic topography in a band between 7.5°N and 7.5°S in the Pacific Ocean are drawn from Seasat altimeter data. They show a set of eddies 600 km in diameter and 15?20 cm in amplitude moving ...
