Skew-T Procedure
In the past, the thickness of layers could be determined manually by reference to the plotted virtual temperature curve and the thickness scales on the skew-T diagram. Nowadays, thickness is typically computed and displayed on electronic versions of the Skew-T diagram. On the intereractive Skew-T, the thickness of the 1000-500 hPa layer is output to the right-hand side of the diagram.
