Sentences with phrase «ocean wind stress»

Not exact matches

«To put this in some kind of context, if those small scale eddies did not increase with wind stress then the saturation of carbon dioxide in the Southern Ocean sink would occur twice as rapidly and more heat would enter our atmosphere and sooner.»

The project, called Estimating the Circulation and Climate of the Ocean (ECCO), uses observational data — including ocean surface topography, surface wind stress, temperature, salinity profiles and velocity data — collected between June 2005 and December Ocean (ECCO), uses observational data — including ocean surface topography, surface wind stress, temperature, salinity profiles and velocity data — collected between June 2005 and December ocean surface topography, surface wind stress, temperature, salinity profiles and velocity data — collected between June 2005 and December 2007.

The conditions also bolster the views of ice and climate specialists who have stressed that the many factors shaping Arctic conditions year by year, from winds and atmospheric pressure to highly variable ocean currents and soot, still dominate the influence of heat trapped by building greenhouse gases.

In this paper, the intensity and the spatial structure of ocean - atmosphere feedback terms (precipitation, surface wind stress, and ocean surface heat flux) associated with ENSO are evaluated for six different reanalysis products.

One the main key surface parameters involved in the exchange of energy between the atmosphere and oceans are: wind stress, surface turbulent latent and sensible heat fluxes.

Hence from the point of view of the atmosphere, the ocean can be considered effectively stationary; from the point of view of the ocean, the atmosphere imposes a significant wind stress on its surface, and this forces large - scale currents in the ocean.

On the relationship between the meridional overturning circulation, alongshore wind stress, and United States East Coast sea level in the Community Earth System Model Large Ensemble (Journal of Geophysical Research - Oceans)

Oceanic currents are largely driven by the surface wind stress; hence the large - scale atmospheric circulation is important to understanding the ocean circulation.

Environmental variables estimated over larger spatial and temporal scales included the upwelling index (UI) for 48 ° N, 125 ° W (http://www.pfeg.noaa.gov), an indicator of upwelling strength based on wind stress measurements, as well as the Pacific Decadal Oscillation (PDO, http://jisao.washington.edu/pdo/PDO.latest), a composite indicator of ocean temperature anomalies [33], seawater temperature from Buoy 46041 ∼ 50 km to the southwest from Tatoosh (www.ndbc.noaa.gov), and remote sensing of chl a (SeaWiFS, AquaModis).

The driver of the MOC seems dominantly to be the wind stress forcing at the Southern Ocean with the North Atlantic playing a much smaller role.

McGregor, S., Sen Gupta, A. & England, M. H. Constraining wind stress products with sea surface height observations and implications for Pacific Ocean sea - level trend attribution.

Hartmut Grassl, (1976), The dependence of the measured cool skin of the ocean on wind stress and total heat flux, Boundary Layer Meteorology

Alternatively, it may be the result of increased ocean heat transports due to either an enhanced thermohaline circulation (Raymo et al., 1989; Rind and Chandler, 1991) or increased flow of surface ocean currents due to greater wind stresses (Ravelo et al., 1997; Haywood et al., 2000), or associated with the reduced extent of land and sea ice (Jansen et al., 2000; Knies et al., 2002; Haywood et al., 2005).

Semipermanent anticyclones (high surface pressures), which tend to develop on the eastern sides of the world's ocean basins, result in alongshore surface wind stresses.

The zonal integral (east to west) of wind stress curl across an ocean basin is proportional to the western boundary current transport (i.e., the transport responsible for the dominant part of the poleward heat flux by the ocean).

For climate, vector winds are required to compute wind stress curl, an essential climate quantity that drives Ekman pumping and suction in the ocean, thereby implying vertical circulations (i.e., upwelling and downwelling).

The Ekman upwelling from the wind stress curl associated with these structures plays an important role in ocean circulation theory, as well as in ocean biology from upwelling of nutrients from the deep water into the upper ocean where they can be utilized by phytoplankton.

In this paper the output from several different runs of a global ocean GCM is used to show that the inflow of upper kilometer water in the South Atlantic and the outflow of deep water varies in direct proportion to the westerly wind stress in the circumpolar region of the southern hemisphere.
