<br />1. Combine fields on composite charts in a Lambert conformal <br /> <br />projection for standard pressure levels of interest, <br /> <br />2. Provide three-dimensional vertical structure of fields, and <br />3. Display vertical cross sections of fields. <br /> <br />These software packages were designed to automatically determine <br />the location, number of levels and fields on the objective analysis <br /> <br />file, read this file and display all or selected field information. <br /> <br />The objective analysis software provides specific identification of <br /> <br />fields, their grid size, latitude and longitude and band-pass filter <br />coefficients on the header records of the output fields. <br /> <br />3.3 Kinematic and Thermodynamic Analysis Equations <br /> <br />The basic equations used in the kinematic analyses are the equa- <br /> <br />tions for divergence and advection on a constant pressure surface. The <br /> <br />equation of continuity of the form: <br /> <br />au + av + aw = 0 <br />ax ay ap <br /> <br />(8) <br /> <br />On a constant pressure surface, divergence becomes: <br /> <br />~ V = au + av- _ aw <br />ax 8y ap <br /> <br />(9) <br /> <br />.D.w <br />vpV = .D.p <br /> <br />Therefore, the vertical motion may be expressed assuming <br /> <br />continuity: <br /> <br />n <br />~ = W + (isi,gn) L: - ;..;p dp (fLbarls) <br />too <br /> <br />(10) <br /> <br />45 <br />
