ECMWF analysis plots for CARIBIC flight 309 from Frankfurt to Caracas on 22 September 2010



Much air uplifted from the Atlantic ocean was sampled in the (sub)tropical high pressure air southwest of a tropopause fold/streamer at about 20 W, later than about 13h UT. See e.g. the trajectories for 13-14 h.
