MCS.
Vroeg me af wat FI By Jet beteknde, even opgezocht, zie beneden:
INTENSIFICATION BY JET CROSSING: FI BY JET
There is a period within the life-time of the frontal cloud band where cloudiness is intensified in the left exit region of a crossing jet streak. This phase is not directly associated with the cut-off development and the flood event, but as it is accompanied by many thunderstorms over a rather long period of time it results in a heavy rainfall situation already prior to the main flood situation.
