Identifying the presence or absence of clouds on the Skew-T log (p) diagram is not a perfect science. While clouds can be quite easy to identify in many circumstances, it can also be incredibly difficult or fundamentally impossible. Clouds have an infinite variety of shapes, but a limited number of forms corresponding to different physical processes in the atmosphere which are responsible for their formation and evolution. During the summer, most clouds are formed by a process called convection. On many summer days, convection will result in a scattered or broken cumulus deck. In this workshop, we’ll look at how to use the Skew-T log (p) diagram to tell if the sky will be clear or if cumulus clouds will form.
