Observations from two new spaceborne microwave instruments in 1999 clearly reveal the atmospheric manifestation of tropical instability waves north of the Pacific equatorial cold tongue. A unique zonal-temporal band-pass filter enables the isolation of the propagating signals and the determination of their phase differences. The phase differences between(More)
In spite of the observational limitation, Delcroix and Henin (1991) attempted to quantify the role of surface hydrologic forcing in the seasonal variability of sea surface salinity (SSS). Seasonal and interannual variations of SSS and sea surface temperature (SST) were analyzed in the south Pacific convergence zone (SPCZ) (Gouriou and Delcroix, 2002).(More)
An improved algorithm is developed based on support vector regression (SVR) to estimate horizonal water vapor transport integrated through the depth of the atmosphere (Θ) over the global ocean from observations of surface wind-stress vector by QuikSCAT, cloud drift wind vector derived from the Multi-angle Imaging SpectroRadiometer (MISR) and geostationary(More)
[1] The mass change of South America (SA) continent measured by the Gravity Recovery and Climate Experiment (GRACE) imposes a constraint on the uncertainties in estimating the annual variation of rainfall measured by Tropical Rain Measuring Mission (TRMM) and ocean moisture influx derived from QuikSCAT data. The approximate balance of the mass change rate(More)
Over the warm pool of the equatorial Indian and western Pacific Oceans, both the climatological mean state and the processes of atmosphere–ocean interaction differ fundamentally from their counterparts over the cold tongue of the equatorial eastern Pacific. A model suitable for studying the coupled instability in both the warm pool and cold tongue regimes(More)
Many years of high-resolution measurements by a number of space-based sensors and from Lagrangian drifters became available recently and are used to examine the persistent atmospheric imprints of the semipermanent meanders of the Agulhas Extension Current (AEC), where strong surface current and temperature gradients are found. The sea surface temperature(More)
Past studies of oceanic influence on terrestrial and cryospheric hydrological cycles were consisted largely of showing the relation between precipitation over landmasses and the surface temperature of surrounding oceans, based on numerical model simulation and analysis of model products. The long-term acceleration of the hydrologic cycle was mainly(More)
