The hypothesis is that improving the parent global model forecast is anticipated to produce better initial and lateral boundary conditions for the next SCDI analysis, and thus impact the end-to-end cycling through the next COAMPS-TC forecast and the next NAVGEM forecast. To validate this hypothesis, the full sequence of 40 six-hourly SCDI analyses with AMVs at 15-minute intervals throughout the lifecycle of Hurricane Joaquin are upscaled to the NAVGEM grid. The NAVGEM forecasts each six hours are compared with the operational NAVGEM that utilizes synthetic vortices to represent Hurricane Joaquin from the National Hurricane Center warning messages. A special objective is to improve the NAVGEM track forecasts after Hurricane Joaquin had struck the Bahamas and reversed course to move northeastward, because the operational NAVGEM forecasts had forecast Joaquin would move to the east coast of the United States. These poor NAVGEM forecasts are attributed to the synthetic vortex not representing the vortex structure and outflow structure above 400 mb. Therefore, incorporating the full three-dimensional vortex structure from the SCDI analyses based on the rapid scan AMVs is expected to greatly improve the track forecasts as the outflow from Hurricane Joaquin interacts with the midlatitude trough to the west over northern Florida.
