individual developing and nondeveloping cases, especially in a three-dimensional sense. The present study aims to perform a detailed analysis of the structural evolution of kinematic and thermodynamic fields (viz., vorticity, divergence, temperature anomaly, and relative humidity) with the goal of highlighting differences in developing and nondeveloping tropical convective systems. Furthermore, by examining the evolution of these fields in three dimensions on a case-study level, this study acts to build

(e.g., Caya and Zawadzki 1992 ) in deducing kinematic properties. Because of the mathematical similarity to the VAD, the proposed methodology is coined distance velocity–azimuthal display (DVAD). This paper is organized as follows. Section 2 presents the rationale and the mathematic framework of the DVAD. Section 3 illustrates characteristics of DVAD on several simple, analytical flow fields. Section 4 demonstrates how to quantitatively deduce flow characteristics via least squares fitting

trend and variability. The most important feature of the hindcast was the rigorous attention devoted to producing the wind fields used to drive the wave model. To remove potential biases in the historical wind fields, all wind observations from ships and buoys were reassimilated into the analysis taking account of the method of observation, anemometer height, and stability. Wind fields for all significant storms were then painstakingly kinematically reanalyzed. Furthermore, high-resolution surface

sacrifices more detailed analyses. As such, this study should be seen as a first step toward characterizing microphysical and kinematic structures in northeastern U.S. winter storms, perhaps providing a roadmap for future, more detailed analyses. In our analyses, we find a number of consistent, reliable polarimetric and Doppler signatures related to microphysical, thermodynamic, and kinematic processes within these storms. The following section provides an overview of the data and methods used in the
