| Descripción: | Pressure change areas in the 500 mb level move with 60% of the speed of the wind in that level. Advection of cold (warm) air at upper isobaric levels is followed by geopotential falls (rises) at the same levels. The prognostic usefulness of this rule is much higher in the 500 mb level than in the 700 mb level. — There are strong indications of dynamic interaction between flow patterns in distant regions on the hemisphere. A deepening of one upper trough will in special cases lead to a second deepening downstream. — In a deepening trough the cold tropospheric air is shown to be sinking at the same time as the jet stream increases and the front becomes sharper. Models of the distribution of vertical motion and divergence in the frontal zones are given.DOI: 10.1111/j.2153-3490.1949.tb01927.x |
