Fig. 5: Forecast tracks for cyclones (a) Jal and (b) Thane in the CTL (without radar
data assimilation) and EXP (with assimilation of radial wind and reflectivity, EXPRV
corresponds to experiment with radial wind alone).
Fig. 6: Forecast track errors for cyclones (a) Jal on 6 th -7 th Nov 2012 and (b) Thane on
29 th -30 th Dec 2011. The CTL runs is the control without the use of DWR data, EXP is
the experiment with the assimilation of both radial wind and reflectivity and EXPRV
corresponds to experiment with radial wind assimilation alone.
