| Research Abstract |
Uncertainty associated with tropical cyclones is investigated. First, we found that large analysis error indicates tropical cyclogenesis a few days later. Secondly, we developed a method to modify near core pressure observations to assimilate them into an atmospheric general circulation model of about a 100-km horizontal resolution. Finally, ensemble forecast experiments indicate importance of a high-resolution sea-surface temperature (SST) dataset to resolve fine SST anomalies and represent convective precipitation associated with a tropical storm.
