ECMWF analysis plots for CARIBIC flight 525 from Munich to Cape Town on 30 November-1 December 2015


Trajectories



The backward trajectories ending at 2-3h (and for samples 37 and 38 see below) show strong uplift by deep convection at 10 S about 20 hours before, see also IR cloud photograph for 30 November 6h UT.
There are also convective influences from East Africa between 1-2h and in samples 32-33
