IMPROVED UNDERSTANDING AND PREDICTIONS FROM TROPICAL CYCLONE INTENSITY (TCI) DATASETS
Abstract
Funds are provided to perform collaborative research to improve understanding of tropical cyclone (TC) intensity and structure changes based on the TCI-15 field experiment and the resulting data sets. Several collaborative tasks are proposed that will utilize the storm-relative High Density Sounding System (HDSS) observations collected for each TCI-15 mission. First, diagnostic studies of Hurricane Joaquin and other TCI-15 storms will be carried out with the TCI version of the SAMURAI/COAMPS Dynamic Initialization (SCDI) analyses. Two other collaborations will blend the HDSS observations with the special CIMSS-produced Air Motion Vectors and the NASA HIRAD surface wind speeds to better describe the outflow and the boundary layer flow. The HDSS observations will also be utilized for COAMPS-TC initial conditions and for validation. A fully-interactive version of the SCDI will be developed that fully utilizes the high temporal and spatial resolution AMVs from TCI-15, Himawari-8, and future GOES-R satellites. The improved initial conditions and model physics to be achieved from the overall TCI-15 project are expected to lead to improved 12 h ~ 72 h COAMPS-TC intensity forecasts. The objective is to improve TC (typhoon or hurricane) intensity and structure forecasts for the Fleet afloat and ashore.
