The plots below show ASCAT diagnostics (analysis and first guess vs. observations) for three assimilation cycles during the life-time of Pam. In the first example (from 9 March 12z), there are a cluster of vectors that got the wrong direction assign due to the position error in the first guess. The second example is an example (11 March 00z) of a good first guess which led to good usage of the vectors. In the third example (12 March 00z) many vectors were rejected due to the strong wind speeds.
3.2 HRES
The plot below shows all HRES forecast valid 13 March 00z. All forecasts have a cyclone in the area although the first four forecasts (initialised 3-6 March 00z) had a weak cyclone. The forecasts from 7-10 March had the cyclone somewhat too the east of the observed position.
