The plot below shows the evolution of central pressure in Best Track (dots) and LWDA analysis (solid line). The analysis had difficulties to capture the intense phase on 5 September, but captured the second intensification.
The plots below show time-series observation statistics for temperature observations from dropsondes within 1 (left) and 5 (right) degrees of Florence.
During the lifetime of Florence an increased number of observations of ocean floats was noted (see first plot). These additional floats were ALAMO (Air-Launched Autonomous Micro Observer) float, 10 floats deployed by WHOI in order to monitor Hurricane Florence, in the predicted path of Hurricane. These floats descend to 300m every 2 hours. The behaviour of the data assimilation was checked and most response in our ocean system is already visible in the model background, which did a very good job in representing the cooling/deepening effect during Florence event. And DA only slightly corrected the temperature fields.
