have focused on the kinematics and dynamics associated with the misocyclones, but IHOP_2002 affords the possibility of combining such measurements with the thermodynamics to obtain a complete picture of the impact of misocyclones and convergence areas on the moisture distribution along boundaries, as well as the relevance of these features to convection initiation. Two such studies examining these relationships among moisture, misocyclones, and CI are presented in this special issue by Murphey et

moisture, realistic cloud microphysics, and no idealizations of the vortex produce features with the properties of vortex Rossby waves similar to those in the idealized vortex ( Chen and Yau 2001 ; Chen et al. 2003 ; Braun et al. 2006 ). There is also support from radar observations. Reasor et al. (2000) analyzed aircraft radar data collected in Hurricane Olivia (1994) at 0.5-h intervals for 3.5 h and found rainbands exhibiting structural and kinematic characteristics of wavenumber-1 and -2 vortex

–wave interactions, wave–bottom friction, and wave–current interactions. Though it is well understood that decreasing SST, strong vertical wind shear, and/or dry-air infiltration can weaken TCs, it remains unclear to what extent these processes result in reduced TC intensity during ET, when baroclinic and frontogenetic processes become important to cyclone maintenance and structure. Given the propensity for ET to occur within environments characterized by sharp horizontal kinematic and thermodynamic gradients

thetropopause exhibit differences in structure, are generated by distinct dynamical processes, and may occurindependently of each other, the respective designationsof "surface" or "low-level" and "upper-tropospheric"or "upper-level" serve as a convenient classificationfor frontal phenomena and processes. Fronts owe their existence in a kinematic sense (Petterssen, 1936, 1956; Miller, 1948) to spatially differential advection of the thermal and wind patterns resulting from sheared horizontal and vertical

enters the updraft where it is stretched vertically, and 4) convergence beneath the updraft is enhanced by the outflow. Davies-Jones also showed kinematically that the flow responsible for tilting and concentrating vortex lines also tilts and packs isentropic surfaces, thus explaining observations of strong entropy gradients across mesocyclones near the ground. c. Potentially relevant simulation results Davies-Jones and Brooks (1993) showed that the vertical vorticity of air parcels descending in an

QG forcing. b. The refined Sutcliffe formulation This formulation [Eqs. (2b) , (3a) , and (3b) ] is Galilean invariant, and moreover from a purely kinematic standpoint is free from cancellation effects. The latter deduction follows because geostrophic flow at any level comprises the two independent components of vorticity and deformation and the formulation’s two terms relate separately to these components. 1) The Sutcliffe term The Sutcliffe forcing term, 2 f 0 [(∂ v G /∂ z ) ⋅ ∇ H ] ζ G
