An area with a high probability for the initiation of convection is the leading edge of Cold Front cloud bands. The initiation of convection only happens where there is an appropriate tropospheric structure (see Meteorological physical background and Key parameters). The images above show a typical situation where convective cells have developed within a frontal zone. A series of very well developed MCSs can be observed from Tunisia across Italy and the Adriatic Sea to Croatia.
In the IR image (left) the cells are generally much brighter than the surroundings.
The black stripes in the WV image (right) around the cells are typical features associated with MCS.
