Storm-Relative Eulerian Absolute Angular Momentum Tendency in Atlantic Tropical Cyclones: Advection and Torques and Their Relative Roles in Vortex Strengthening
This study examined inner-core sources and sinks of angular momentum in Atlantic tropical cyclones. Each advective and torque term in the Eulerian absolute angular momentum tendency equation was calculated in a storm-relative reference frame using modeled and observational data. 18 storms between 2004 and 2006 were simulated using the hurricane weather research and forecast (HWRF) model. In addition, 30 composite observational data sets from the Atlantic oceanographic and meteorological laboratory's (AOML) H*Wind archive were gathered. These included aircraft, satellite, offshore buoy, coastal, and ship observations. Through methods of statistical correlation, categorical composition and linear regression, it was found that mid-level horizontal advection of relative angular momentum was most relevant to 12 hour strength change in the modeled tropical cyclones, while observed storms favored mid-level horizontal advection of Earth's angular momentum.
