Convergence Cloudiness - Cloud Structure In Satellite Images
by ZAMG
- IR10.8: often a little bit warmer cloud tops than those associated with the Occlusion cloud, therefore light grey in the IR image, sometimes
fibrous and broken
- VIS0.8: light grey
- WV6.2: varying from very bright to light grey
- Airmass RGB: High reaching and a little darker clouds than the associated Occlusion cloud band.

In the following example a Convergence Cloud Shield is shown where the cloud tops of the Convergence Shields are sometimes warmer, and sometimes the same as the Occlusion spiral. At the transition from Occlusion cloudiness to Convergence Cloudiness cloud tops are lower.
