Monthly Weather Review A Filtering Method for Gravitationally Stratified Flows
Gravity waves arise in gravitationally stratified compressible flows at low Mach and Froude numbers. These waves can have a negligible influence on the overall dynamics of the fluid but, for numerical methods where the acoustic waves are treated implicitly, they impose a significant restriction on the time step. A way to alleviate this restriction is to filter out the modes corresponding to the...

Simultaneous measurements of turbulent vertical velocity fluctuations at a height of 300 ft. measured by means of a fixed anemometer, small floating balloons, and airplane gust equipment at Brookhaven are presented. The resulting Eulerian (fixed anemometer) turbulence energy mectra are similar to the Lagrangian (balloon) spectra but "-with a displacement toward higher frequencies. The term Eule...
متن کاملMonthly Weather Review Seamless precipitation prediction skill in the tropics and extratropics from a global model
Abstract: The skill with which a coupled ocean-atmosphere model is able to predict precipitation over a range of time scales (days to months) is analysed. For a fair comparison across a seamless range of time scales, the verification is performed using data averaged over time windows equal in length to the forecast lead time. At a lead time of one day, skill is greatest in the extratropics arou...
متن کاملExtracting envelopes of non-zonally propagating Rossby wave packets. Submitted to Monthly Weather Review
In this note we propose an improved technique to extract envelopes of wave packets of synoptic scale Rossby waves. In the currently used techniques the wave packets are assumed to be propagating along latitude circles. In our new technique, we take into account the possibility that the waves may propagate in a direction that is not purely zonal. We demonstrate the advantages of the new techniqu...

An 18-vertical level primitive equation general circulation model was developed from previous models of the Geophysical Fluid Dynamics Laboratory in order to study t,he lower stratosphere in detail. The altitude range covered was from the surface to 4 mb. (37.5 km.), the vertical resolution being optimized in the tropopause region to permit a more accurate calculation of the vertical transport ...
