Tropical Cyclone Gamede was forecast for reach Madagascar on 23rd . Missed because of interpretation of model & IR data

ARPEGE ECMWF UKMO
Some disagreements between the three models;eg the vortex associated with tropical cyclone Flavio is not captured by the ECMWF, and the intensity is different in ARPEGE and UKMO.Model intercomparison + satellite imagery allows forecasters to decide on which one to use to predict specific features on specific regions.
ResearchTo improve our products to suit the NMHSs & other end users ie improve our forecast & predictibility for human security,for early warning systems, food security etc in order to reduce the socio-economic effects of high impact weather.
Regional Modelling
Model Evaluation & Intercomparison
Forecast evaluation
Document interesting case studies for later use in our project (ACMAD, NMHS, European partners, Americans?) of writing a forecaster’s handbook; Still seeking funds!!!
