Which front does a frontal cyclone usually begin with?

• A. Warm Front
• B. Cold Front
• C. Occluded Front
• D. Stationary Front

Answer: (A)

Frontal cyclones form along boundaries between contrasting air masses, and the first boundary that establishes as the system begins is the warm front. The lighter warm air starts to override the cooler air ahead of it, creating a warm-front boundary where broad lifting and spreading rain or clouds often develop. As the storm intensifies, a cold front forms behind it as cooler air wraps in, and later this cold front can catch up to the warm front to create an occluded front. So the warm front is the initial front that usually begins the process.
