On the response of Southern Ocean water-masses to atmospheric meridional moisture advection
[1] We investigate the role of atmospheric moisture advection in determining Southern Ocean water-mass properties in a coupled climate model. Two sensitivity experiments are presented in which the winds advecting moisture are either reduced or enhanced south of 45 S. It is shown that a variation in meridional winds in the Southern Ocean can generate large anomalies of subsurface potential tempe...
متن کاملSatellite observations of mesoscale ocean features and copropagating atmospheric surface fields in the tropical belt
[1] Recent studies of air-sea interaction using satellite data have shown a high positive correlation between wind speed and sea surface temperature (SST) over mesoscale ocean features in certain frontal regions. The aim of this study is to determine to what extent mesoscale ocean dynamics modifies the surface wind speed over the global tropics between 40 S and 40 N. Cross-spectral and linear r...
متن کاملSatellite Observations of Cool Ocean – Atmosphere Interaction
| H igh sea surface temperature (SST) is generally required for deep convection that reaches the tropopause. In the current climate, the SST threshold for deep convection is somewhere around 26°–27°C, depending upon region and season (Gra-ham and Barnett 1987; Waliser et al. 1993). Over such warm oceans, SST changes cause deep convective adjustment , which in turn excites the dynamic response o...
متن کاملMapping Atmospheric Moisture Climatologies across the Conterminous United States
Spatial climate datasets of 1981-2010 long-term mean monthly average dew point and minimum and maximum vapor pressure deficit were developed for the conterminous United States at 30-arcsec (~800m) resolution. Interpolation of long-term averages (twelve monthly values per variable) was performed using PRISM (Parameter-elevation Relationships on Independent Slopes Model). Surface stations availab...
متن کاملThree improved satellite chlorophyll algorithms for the Southern Ocean
[1] Remote sensing of Southern Ocean chlorophyll concentrations is the most effective way to detect large-scale changes in phytoplankton biomass driven by seasonality and climate change. However, the current algorithms for the Sea-viewing Wide Field-of-view Sensor (SeaWiFS, algorithm OC4v6), the Moderate Resolution Imaging Spectroradiometer (MODIS-Aqua, algorithm OC3M), and GlobColour significa...
