= Post-tropical cyclone
{wiki=Post-tropical_cyclone}
A post-tropical cyclone is a storm system that has lost its tropical characteristics, typically due to cooler sea surface temperatures or interaction with land. While it may still retain some features of a tropical system, such as a well-defined circulation, it no longer meets the criteria to be classified as a tropical storm or hurricane. Post-tropical cyclones can take on a variety of forms, including extratropical cyclones, which are characterized by fronts and a temperature gradient.
