<br />inflow to the updraft, thereby contributing to the longevity of the <br />storm. The three-dimensional complexity of the flow observed in <br />Dopplar radar and simulated in model analyses further emphasizes the <br />need for meso-Y scale observations of the flow that initiates and <br />maintains precipitation systems. Models by Moncrieff and Green <br />(1972) and Schlesinger (1982a) indicate the importance of shear to <br />convective propagation. <br /> <br />Schlesinger (1982b) has prepared a comprehensive review of <br />three-dimensional cloud modeling of convective storms. This review <br />clearly shows the need for three-dimensional surface and upper-level <br />objective analyses and numerical cloud models to fully describe and <br />understand the complex cloud-scale and mesoscale processes that <br />control convective clouds and precipitation. <br /> <br />1.4.3 Objective Analyses <br /> <br />Mesoscale objective analysis has become an important tool in <br />improving our understanding of convective storms. The Barnes (1964, <br />1973) objective analysis system was used by scientists examining <br />severe local storms in SESAME (Arnold, 1982; Jedlovec and Fuelberg, <br />1982; Wilson, 1982), mesoscale convective complexes in the High <br />Plains (Maddox, 1982; Maddox and Doswell, 1982) satellite-derived <br />storm kinematics (Anderson, 1982; Wilson and Houghton, 1979; Goodman <br />et ale 1982) and the evolution of squall lines and intense convection <br />(Doswell, 1977). In this study, the technique developed by Barnes <br />(1973), and modified by Doswell (1977) and Maddox (1980a) is employed <br />to improve our ability to resolve meso-p scale features affecting <br /> <br />27 <br />
