Convection RGB (Severe Storms RGB)
Operationally produced by EUMETSAT
Application:
Monitoring convection in mature phase; detection of severe storms.
Convection RGB allows an easy monitoring of CB clouds and identification of small ice particles (potentially more severe – yellow) or large ice particles (potentially less severe – red).
Limitations:
Only daytime (especially at noon and close to the noon hours).
Pros and cons:
✓ Yellow colour in case of severe convection is a very good alert.
✓ Other information is limited.
X Also non-convective Lee clouds and clouds containing atmospheric dust can appear in yellow colour.
X In N, E and NE Europe not so applicable because of low satellite viewing angle.
X Night-time storms cannot be monitored.
