This Webcast, presented by Dr. Jim Moore of St. Louis University, covers the advantages and applications of diagnosis and visualization of large-scale flow and vertical motion on surfaces of constant potential temperature. The movement of moisture along these surfaces is emphasized, as is the diagnosis of the components of vertical motion. Background mathematical concepts are presented, then illustrated with soundings, cross sections, and plan view analyses of data from multiple cases.
1. Understand the concepts of pressure advection and system relative flow.
2. Understand dynamic destabilization and associated environmental moistening.
3. Diagnose static stability, upper fronts and CSI in this framework.
4. Examine at frontogenesis and transverse jet streak circulations on vertical cross sections with analyzed potential temperature fields.
5. Examine the components of vertical motion in an isentropic framework.
6. Compare the advantages and disadvantages of isentropic analysis.
7. Examine a wintertime case study utilizing isentropic analysis.
