4/11 notes taken by Elle Gossman Drylines are similar to fronts, only while fronts are air masses with different temperatures, drylines are air masses with different humidities (but similar temperatures). The strong humidity gradients allow them to serve as fronts, and thunderstorms tend to form near drylines. Drylines often form in the Great Plains. Occluded fronts are fronts where two fronts run into each other, and occluded fronts usually move sideways. Cloudtocloud lightning is when there’s an electrical discharge within and between clouds. The electrical gradient has to be big enough that the air’s natural resistance can’t keep up. Because cloudcloud is often obscured by the clouds, it’s sometimes called sheet lightning.
