When a rising air parcel stays warmer than its surroundings, it keeps accelerating upward — the fuel for thunderstorms. The pink area between the parcel and environment curves is CAPE, the convective available potential energy. Large CAPE means tall, violent storms; a stable profile suppresses them. This is the core of severe-weather forecasting.

Governing equation
Reading this result: Steep environmental lapse (7.5 °C/km) keeps the parcel far warmer than its surroundings all the way up — huge CAPE fuels tall, violent updrafts.
