A weak migratory low pressure trough in the low latitudes is often called an easterly wave. This is because it typically moves from east to west, and can bring areas of low pressure and thunderstorms along with it. Tropical cyclones are a much stronger and more organized type of low pressure system, while extratropical cyclones and occlusions are associated with mid-latitude weather patterns. Thunderstorms can occur with any of these systems, but do not necessarily define them.
