Example
- Narrow Black Stripes along the cyclonic side of bright WV bands and fibres
- Represent dry (sometimes stratospheric) sinking air
- Can be used as indication of:
- Cloud dissipation from above
- Cyclogenesis
- Location of jet axis
- Location of left exit region in a jet streak
- Also seen in other conceptual models:
- Rapid Cyclogenesis
- Wave
- Jet cloudiness (fibre at jet axis)
- Front Intensification by Jet Crossing
- Cold Front
- Occlusion
The example shows an extended Dark Stripe from Poland towards Spain.
