Question

Quizplus · Accepted Answer

Classical cyclogenesis occurs when a polar front separates masses of warm and cold air. This sets up a boundary where the two air masses can interact and lead to the development of a low-pressure system, which is the next step in the process. The warm air does eventually flow south, but this typically happens after the low-pressure system has already formed. A distinct warm front may form later as part of the cyclone's life cycle, but it is not the first step.
