Temperature/Levels » Thickness Skew-T Procedure
In the past, the thickness of layers could be determined manually by reference to the plotted virtual temperature curve and a thickness scale on the printed skew-T. Nowadays, thickness is typically computed and displayed on electronic versions of the skew-T. On the Interactive Skew-T accompanying this module, the thickness of the 1000-500 hPa layer is calculated and shown on the right-hand side of the diagram once you click on the "CAPE" menu item at the top.
