Definitive Guide to Skew-Ts and Hodographs - Part 1 - Components of a Skew-T

Welcome to my Definitive Guide to Skew-Ts and Hodographs! In this multi-part series, we'll take a deep dive into deciphering those complicated skew-T log-P diagrams and hodographs, which are both critical tools in severe weather forecasting. In this video (Part 1), we discuss just what all those lines on the skew-T log-P diagram represent. While it might look like a jumbled mess at first, each set of fixed lines has a purpose, and once you know what each means, you'll be able to better understand what a skew-T log-P diagram is showing.
