The Importance of Shortwave Troughs and How to Identify Them
WebPassage of a shortwave often initiates the formation of a surface low. Cyclone development: •baroclinic instability (baroclinic means temperature varies on an isobaric surface) causes initial ‘perturbation’ to grow. •occurs in the presence of strong temperature gradients. Imagine a short wave trough passes overhead (looking North): WebA filling major short-wave trough is indicated by stronger Negative Vorticity Advection (NVA) behind the trough than Positive Vorticity Advection (PVA) ahead of the trough.
