Unformatted text preview: Lab - AOS 330 Geopotential Heights and Thickness 1 Objectives • Learn how the hypsometric equation governs real-world pressure/height patterns. 2 Materials • Access to world-wide web • Height/thickness table (to be filled out) • Height cross-section chart • Thickness cross-section chart 3 Introduction The hypsometric equation relates the vertical spacing (“thickness”) between pairs of pressure levels to the layer mean virtual temperature. Δ Z = R d T v g ln p 1 p 2 . Horizontal temperature gradients at lower levels therefore translate into changes in pressure patterns at higher levels. An east-west jetstream at 500 hPa, for example, is the direct result of strong north-south temperature contrasts. This lab allows you to observe the relationship first-hand by analyzing data from a series of North American upper air stations. 4 Procedure 1. Go to http://weather.uwyo.edu/upperair/sounding.html 2. Set the plot type to GIF:Skew-T 3. Set the date/time to 2006 Mar 13/12Z (start)...
