Surface drag contribution to the depth of monsoon depression over Indian region

Der Beitrag der Bodenreibung zur Vertiefung der Monsun-Depression über Indien

  • 35 Accesses


The effect of surface drag to the depth of monsoon depression over India has been computed using a quasigeostrophic ω-equation. The rate of intensification in an average monsoon depression of radius 1000 km and extending up to 500 mb in the vertical is shown to be of the order of 4 mb/day which is very near to the observed values.


Die Wirkung der Bodenreibung auf die Vertiefung der Monsun-Depression über Indien ist mit einer quasigeostrophischen w-Gleichung berechnet worden. Es wird gezeigt, daß der Betrag der Vertiefung einer Monsun-Depression vom Radius 1000 km und mit einer Erstreckung in die Vertikale bis 500 mb von der Größenordnung von 4 mb pro Tag ist, was den beobachteten Werten sehr nahe kommt.
