Sentences with phrase «momentum flux»

Cospectral analysis of eddy momentum flux convergence shows that eddy activity is generally restricted by these phase speed bounds.

Bushell, A.C., N. Butchart, S. H. Derbyshire, D.R. Jackson, G.J. Schutts, S.B. Vosper, and S. Webster, 2015: Parameterized Gravity Wave Momentum Fluxes from Sources Related to Convection and Large - Scale Precipitation Processes in a Global Atmosphere Model.

«Intraseasonal to interannual variability of Kelvin wave momentum fluxes as derived from high - resolution radiosonde data.»

It is shown how such stirring, as represented by a simple stochastic forcing in a barotropic model, leads to a variability in the zonal flow via a variability in the eddy momentum flux convergence and to patterns similar to those observed.

The E-sail utilises long, charged tethers to convert natural solar wind momentum flux into spacecraft thrust.

To this end, a group of Swiss researchers at the WSL - Institute for Snow and Avalanche Research (SLF), led by Prof. Michael Lehning, is exploring mass and momentum fluxes during drifting snow events, pursuing an improved understanding of the link between snow cover erosion and deposition.

Poleward eddy momentum fluxes interact with the zonal mean flow to sustain latitudinal displacements of the mid-latitude westerlies (Limpasuvan and Hartmann, 2000; Rashid and Simmonds, 2004, 2005).

Sea ice is an important component of the Earth system; it is highly reflective, altering the amount of solar radiation that is absorbed; it changes the salinity of the ocean where it forms and melts, and it acts as a barrier to the exchange of heat and momentum fluxes between the atmosphere and ocean.

This is associated with a poleward shift of the westerlies at the surface (see Section 10.3.6) and in the upper troposphere particularly notable in the Southern Hemisphere (SH)(Stone and Fyfe, 2005), and increased relative angular momentum from stronger westerlies (Räisänen, 2003) and westerly momentum flux in the lower stratosphere particularly in the tropics and southern mid-latitudes (Watanabe et al., 2005).

Heat - salt momentum flux.

Ait - Chaalal, F., and T. Schneider, 2015: Why eddy momentum fluxes are concentrated in the upper troposphere.

Properties of Rossby waves: phase velocity, group velocity, momentum fluxes, critical layers.

Investigate connections between surface forcing (e.g., freshwater, heat, and momentum fluxes, NAO - related forcing) and historical AMOC variability.

Going from model - calculated OHC back to net flux imbalance in the model with any accuracy is extremely difficult, since as well as the «natural» net flux variation in the pre-industrial control which is integrated in some guise into the GCM's energy accumulation and needs to be discounted, there is also conversion of radiative input into sensible heat and latent heat, conversion to momentum flux and distribution of sensible heat between land, sea and atmosphere.
