describes the kinematic and precipitation structure in more detail during Edouard’s near-rapid intensification on 14 September and near-peak intensity after weakening begins on 16 September, exploring possible mechanisms that can explain the radial, azimuthal, and temporal distribution of deep convection and its influence on intensity change. Previous studies have shown that the structure and distribution of inner-core precipitation is an important determinant of TC intensification. Satellite

Gonzalo in a joint effort from three federal laboratories: NOAA’s Hurricane Research Division, NASA’s Goddard Space Flight Center, and the Naval Research Laboratory. On two consecutive days, airborne radars observed two eyewall replacement cycles, detailing the inner-core reflectivity and kinematic structures at different stages of eyewall replacement. This study will examine these observations to analyze the dynamics and evolution of the asymmetric features in concentric eyewalls. The data were

) generally leads to improvements in TC track ( Aberson and Franklin 1999 ; Chou et al. 2011 ; Majumdar et al. 2013 ) and intensity ( Aberson and Franklin 1999 ; Torn 2014 ) forecasts in global and regional modeling applications. Compared to traditional aircraft, the GH offers much longer range and higher-altitude sampling. GH dropwindsondes deployed in Hurricane Edouard (2014) were used to examine the storm’s thermodynamic and kinematic structures ( Zawislak et al. 2016 ; Rogers et al. 2016 ). These

downdrafts on the downshear side outside the radius of maximum winds (RMW; Riemer et al. 2010 ). The PBL θ E can recover as the air continues to travel through the upshear side and warms and moistens through surface enthalpy fluxes ( Cione et al. 2000 ; Molinari et al. 2013 ; Zhang et al. 2013 ). The structure and evolution of the thermodynamic and kinematic fields of TCs in shear clearly play a role in governing the distribution of inner-core precipitation. Consequently, whether a TC is about to

to examine SAL thermodynamic, kinematic, and dust structures in relation to AEW structure and potential tropical storm development. Specifically, how does Saharan dust modify SAL, AEJ, and AEW structures, and do those changes make conditions more or less favorable for storm development? Karyampudi and Carlson (1988) suggested that the SAL might enhance rising motions in the intertropical convergence zone (ITCZ), thus favoring tropical cyclogenesis, but that with increased dust loading, this
