Content
A Cold Air Development is represented by a cloud spiral at the rear side of a frontal system. As the name already indicatees it is bound to cold air advection. Cold Air Developments often result of enlargening comma systems. Like the comma system they are linked to a PVA maximum. The intensive moving PVA maxima is regarded as the reason for cyclogenesis taking place within the cold air mass.
