Abstract: Time-filtered grid-point data for the northern extratropics in winter have been used to study the local effect on the time-mean flow, arising from the ?synoptic-scale? transient eddies (TE), which have periods between 2.5 ...

Abstract: The distributions of the net sources of atmospheric dry and latent energy are evaluated by the residual technique using the reanalyzed ECMWF FGGE level IIIb data for February and July 1979. Their sum (i.e., the residual ...

Abstract: On the average, there has to be a balance in the atmosphere between the rate at which the potential enstrophy of the transient eddies (TE) is generated by conversion from the time-mean flow and the rate at which it is ...

Abstract: In this paper we investigate the role of high-frequency transient eddies in the maintenance of the blocking high which occurred over Europe on 16-25 February 1979. Time-filtering is used to decompose the atmospheric ...

Abstract: The invertibility principle of potential vorticity (PV) is used, within a quasigeostrophic framework, to formally partition the observed atmospheric flow in various ways. The first method separates the contributions of the ...

Abstract: A short review of atmospheric energy transport studies is given, and the importance of the Global Weather Experiment for such studies is emphasized. The accuracy of energy flux (divergence) estimates is then discussed, ...

Abstract: The effect of transient eddies (TE) on stationary eddies (SE) is studied in terms of how the TEs force the SE isobaric height variance in the northern extratropics. The method used correlates the observed SE height field ...

Abstract: The forcing of the time-mean flow by transient eddies is examined within the framework of a quasi-geostrophic equation relating the geopotential tendency to the convergence of transient eddy transports of heat and vorticity. ...

Abstract: Two long-term simulations of a low-resolution spectral general circulation model (Otto-Bliesner et al., 1982) have been made. The single difference between these two runs is that in one (CONTROL) the horizontal flux of ...

Abstract: The effect of horizontal transports of momentum and heat by transient eddies (TE) on the time-mean flow is studied by examining the relevant terms in a local budget of quasi-geostrophic potential vorticity. Two long-term ...
