[ACG44-06] Assimilation experiments of SSR mode-S downlink data of aircrafts
Keywords:numerical forecast, data assimilation
The mode-S data obtained from the experimental SSR mode S system of the Electronic Navigation Research Institute on 14th Aug. 2015 was assimilated by meso-NAPEX system. On 14th Aug., the intense convections passed the Kanto plain. The assimilation of mode-S data improved the positions of shear lines and convections. The intensity of the rainfalls became similar to the observation. These results indicate that the vertical profiles of horizontal wind converted from mode-S data are useful assimilation data for the improvement of the prediction of the rainfalls caused by convections.
