The Short Wave Broadcasting … SpletShort waves often disappear with height and may not be detectable above 500 mb. This is attributable to the temperature patterns associated with the two types of waves. With long waves, the troughs are cold and the ridges warm; the opposite holds true for short waves. Synoptically, long waves are related to a number of weather occurrences.
Splet15. jul. 1997 · The key feature of this model is the similarity of description for the high- and low-wavenumber regimes; both forms are posed to stress that the air-sea interaction process of friction between wind and waves (i.e., generalized wave age, u/c) is occurring at all wavelengths simultaneously. This wave age parameterization is the unifying feature ...
