dc.description.abstract | Observing System Simulated Experiments (OSSEs) performed during the 2014 North Atlantic
hurricane season quantify ocean observing system impacts with respect to improving ocean
model initialisation in coupled tropical cyclone (TC) prediction systems. The suitability of the
OSSE system forecast model (FM) with respect to the previously validated Nature Run is
demonstrated first. Analyses are then performed to determine the calibration required to obtain
credible OSSE impact assessments. Impacts on errors and biases in fields important to TC
prediction are first quantified for three major components of the existing operational ocean
observing system. Satellite altimetry provides the greatest positive impact, followed by Argo
floats and sea surface temperature measurements from both satellite and in-situ systems. The
OSSE system is then used to investigate observing system enhancements, specifically regional
underwater glider deployments during the 2014 hurricane season. These deployments resulted
in modest positive impacts on ocean analyses that were limited by (1) errors in the horizontal
structure of the increment field imposed by individual gliders and (2) memory loss in the
spreading of these corrections by nonlinear model dynamics. The high-resolution, threedimensional
representation of the truth available in OSSE systems allows these issues to be
studied without high-density ocean observations. | en_US |
