other crucial kinematic parameters mentioned previously. Moreover, in the DAVAD approach, the vertical profiles of horizontal divergence, mean vertical velocity and vertical vorticity are retrieved simultaneously through a linear regression allowing a separation of these three parameters, as specified in section 2b(1) . No assumption is thus needed for the value of the hydrometeor fall speed. In section 2 of the present paper, the principle and mathematical formulation of the DAVAD analysis are

scanning and profiling Doppler radars, rawinsondes, and GPS receivers. This study is unique because it characterizes the kinematic and thermodynamic structures of SBJs, landfalling ARs, and their interaction across the Central Valley and up the windward Sierra slope to the crest along an ~200-km segment of the Sierra in northern California. 2. Observing systems and data processing Locations of the observing systems employed in this study are shown in Fig. 1 . Three scanning Doppler radars were the

1. Introduction Several recent field projects, such as the Mesoscale Alpine Programme (MAP; Bougeault et al. 2001 ), the Intermountain Precipitation Experiment (IPEX; Schultz et al. 2002 ), and the Improvement of Microphysical Parameterization through Observational Verification Experiment (IMPROVE; Stoelinga et al. 2003 ) have collected comprehensive kinematic, microphysical, and precipitation datasets over complex terrain. The primary objectives of these field studies were to advance

OCTOBER 1957CLARENCE E, PALMER403SOME KINEMATIC ASPECTS OF FRONTAL ZONESBy Clarence E. Palmer Florida State University'(Manuscript received 27 February 1957)ABSTRACTIt is possible that the technique of wind analysis, developed long ago by Sandstrom and V. Bjerknes,may supplement the standard isobaric and frontal analysis of surface weather maps. A first approximationto a theory concerning the relation between asymptotes in the wind field and frontal zones suggests thatthe technique might

1. Introduction Observations of pack ice motion show ice deformation occurs along linear features on scales that vary between basin-scale dimensions (Arctic Ocean, hundreds of kilometers, referred to as large scale in this paper; Kwok 2001 ) and the mesoscale (10–70 km; Hibler et al. 1973 ; Hibler 2001a ). These linear kinematic features, referred to as failure zones in this paper, are apparent in analysis of ice motion between synthetic aperture radar (SAR) images ( Kwok 2001 ), where
