This case study will concern a Dark Stripe visible in water vapour imagery behind a Cold Front. This Dark Stripe indicates the presence of descending dry air, which can be of stratospheric origin. The stripe develops along the cyclonic side of the white water vapour band. Typical places of appearance of Dark Stripes are the rear of Cold Fronts and Occlusions, and the forward sides of Warm Fronts.
