Type of front that a frontal cyclone usually begins with?

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

Answer: (A)

Frontal cyclones form along boundaries between different air masses, and the first distinct boundary that usually develops as the system organizes is the warm front. Warm air, being lighter, slides up over the cooler air ahead of the low, creating a broad area of lift that brings widespread cloudiness and light to moderate precipitation ahead of the front. As the low deepens, a cold front forms behind it when colder air pushes in, and this cold front may eventually overtake the warm front to produce an occluded front. So the initial development along a boundary is typically the warm front, which sets the stage for the cyclone’s evolution.
