The Generation of Synthetic Sea Surface Temperature Data for the Equatorial Pacific Ocean
Publisher: American Meteorological Society
Abstract: Synthetic monthly SST anomaly data are constructed using frequency domain analyses of significant principle components derived from reconstructed SST data in the equatorial Pacific Ocean. The model provides insight into ...
The Interaction of a Two-Layer Isolated Mesoscale Eddy With Bottom Topography
Publisher: American Meteorological Society
Abstract: The propagation of an isolated mesoscale eddy onto a western bounding topographic slope is examined through the use of a two-layer, primitive equation, numerical model. Variable parameters in the study are sense of rotation ...
An Introduction to Wavelet Analysis in Oceanography and Meteorology: With Application to the Dispersion of Yanai Waves
Publisher: American Meteorological Society
Abstract: Wavelet analysis is a relatively new technique that is an important addition to standard signal analysis methods. Unlike Fourier analysis that yields an average amplitude and phase for each harmonic in a dataset, the wavelet ...
Reconstruction of Monthly SST in the Tropical Pacific Ocean during 1868–1993Using Adaptive Climate Basis Functions
Publisher: American Meteorological Society
Abstract: An EOF-based reconstruction of monthly SST anomaly fields is calculated for the years 1868?1993 in the tropical Pacific Ocean. The EOFs are computed from optimally interpolated SST anomaly fields from November 1981 to ...
Numerical Simulation of Topographically Forced Mesoscale Variability in a Well-Mixed Marine Layer
Publisher: American Meteorological Society
Abstract: A simple nonlinear numerical model of a well-mixed marine layer is used to study topographically forced mesoscale variability off coastal California. The model is used to simulate a persistent wind maximum observed near ...
Reconciling the Spatial Distribution of the Surface Temperature Trends in the Southeastern United States
Publisher: American Meteorological Society
Abstract: his study attempts to explain the considerable spatial heterogeneity in the observed linear trends of monthly mean maximum and minimum temperatures (Tmax and Tmin) from station observations in the southeastern (SE) United ...
Interdecadal Variability in a Numerical Model of the Northeast Pacific Ocean: 1970–89
Publisher: American Meteorological Society
Abstract: Variations in the thermocline depth of the northeast Pacific Ocean during 1970?1989 are investigated using a reduced-gravity numerical model forced by the local surface wind stress and at the southern land-ocean boundary ...
Objectively Derived Daily “Winds” from Satellite Scatterometer Data
Publisher: American Meteorological Society
Abstract: An objective technique is used to create regularly gridded daily ?wind? fields from NASA scatterometer (NSCAT) observations for the Pacific Ocean north of 40°S. The objective technique is a combination of direct minimization, ...
The Sensitivity to Parametric Variation in Direct Minimization Techniques
Publisher: American Meteorological Society
Abstract: Solutions of some objective analysis techniques are known to depend upon the subjective values of internal parameters. The change in the solution per change in the parameter is the sensitivity. Parameters with low sensitivity ...
