Extreme in der Höhenverteilung zweier meteorologischer Parameter

Zusammenfassung

Es werden einige Produkte aus zwei (höhenabhängigen) meteorologischen Parametern auf ihre Extreme im Vertikalverlauf untersucht (z-System). Die Lage der Extreme wird in Zusammenhang gebracht mit der Lage der Schichten extremer und verschwindender Meridionalgradienten vonp, T und der Windextremschichten.

Summary

In the atmosphere there exist layers with vanishing values (H-layers in Figure 2) of the meridional gradients of pressure, temperature and density. Further: There are three ‘cases’ with regard of the behaviour with altitude of wind and pressure gradientz-system). Case I: both decreasing with height; case II: wind increasing, pressure gradient decreasing with height; case III: both increasing with height. Then: There exist Null Layers (N ₁ connected with wind maximum,N ₂ with wind minimum) which reverse the large scale vertical motion of the air. In the vertical coordinate the three ‘cases’ are separated by theH- and the Null Layers. In this paper the extremes of simple product functions are brought into connection with the above mentioned layers.
