  • Sensitivity analysis provides the basis for decision makers regarding the design of both efficient routine observing networks and special targeted observation strategies. This thesis tackles the application of sensitivity analysis to high impact weather events. This thesis proposes to compute climatological statistical sensitivities by means of a climatology of Mediterranean cyclones and also covers the arduous task of verifying of the derived ensemble sensitivity climatologies together with an already available adjoint-based sensitivity climatology. The performance of the sensitivity climatologies is tested against an experienced meteorologist. Results confirm the improvement of climatological ensemble sensitivities when an ad hoc classification of cyclones is used. However, a significantly superior skill is shown for the human and adjoint sensitivity fields against both ensemble sensitivity climatologies. The ensemble sensitivity technique is also applied to the DTS-MEDEX-2009 targeting cases. The derived ensemble sensitivity products are in agreement with other available sensitivity computations during the targeting campaign.
