RISRotated Global Modes of Non-ENSO Sea Surface Temperature Variability
Publisher: American Meteorological Society
Abstract: A varimax rotation was applied to the EOF modes of global SST derived by Enfield and Mestas-Nuñez. The SST anomaly record is more than a century long, with a global complex EOF representation of ENSO and a linear trend ...
Multiscale Variabilities in Global Sea Surface Temperatures and Their Relationships with Tropospheric Climate Patterns
Publisher: American Meteorological Society
Abstract: El Niño?Southern Oscillation (ENSO) is a global phenomenon with significant phase propagation within and between basins. This is captured and described in the first mode of a complex empirical orthogonal function (CEOF) ...
Eastern Equatorial Pacific SST Variability: ENSO and Non-ENSO Components and Their Climatic Associations
Publisher: American Meteorological Society
Abstract: Using an updated Kaplan et al. global SST anomaly (SSTA) dataset (1870?1999) a canonical representation of El Niño?Southern Oscillation (ENSO) is constructed. When this canonical ENSO is subtracted from the data, a residual ...
Seasonal and El Niño Variability in Weekly Satellite Evaporation over the Global Ocean during 1996–98
Publisher: American Meteorological Society
Abstract: The seasonal and anomaly variability of satellite-derived weekly latent heat fluxes occurring over the global oceans during a 3-yr period (January 1996?December 1998) is investigated using EOF and harmonic analyses. The ...
Water Vapor Fluxes over the Intra-Americas Sea: Seasonal and Interannual Variability and Associations with Rainfall
Publisher: American Meteorological Society
Abstract: The seasonal and interannual variability of moisture transports over the Intra-Americas Sea (including the Gulf of Mexico and the Caribbean Sea) is evaluated using the NCEP?NCAR global reanalysis. The seasonal variability ...
Global Wind Stress and Sverdrup Circulation from the Seasat Scatterometer
Publisher: American Meteorological Society
Abstract: Three months of vector wind observations from the Seasat-A satellite scatterometer (SASS) are used to construct gridded fields of monthly average wind stress and wind stress curl over the global ocean. These fields are ...
Uncertainties in Estimating Moisture Fluxes over the Intra-Americas Sea
Publisher: American Meteorological Society
Abstract: This study estimates discrepancies in moisture flux divergence in the Intra-Americas Sea (IAS; including the Gulf of Mexico and the Caribbean Sea) calculated using sounding observations, the NCEP Eta high-resolution regional ...
Evidence of Time-dependent Sverdrup Circulation in the South Pacific from the Seasat Scatterometer and Altimeter
Publisher: American Meteorological Society
Abstract: Seasat scatterometer and altimeter data are analyzed to investigate time-dependent Sverdrup dynamics in the Southern Ocean (40°S to 60°S) over seasonal time scales. Sverdrup dynamics are shown to be inadequate to describe ...
The Impact of Satellite Winds and Latent Heat Fluxes in a Numerical Simulation of the Tropical Pacific Ocean
Publisher: American Meteorological Society
Abstract: Several oceanic operational programs use remotely sensed fluxes to complement atmospheric operational analyses from major national weather prediction centers. The main goal of this study is to evaluate the ability of the ...
Satellite Estimates of Wind Speed and Latent Heat Flux over the Global Oceans
Publisher: American Meteorological Society
Abstract: Surface fluxes of momentum, freshwater, and energy across the air?sea interface determine oceanic circulation and its variability at all timescales. The goal of this paper is to estimate and examine some ocean surface flux ...
