Which weather phenomenon can be caused by a warm front?

• A. Heavy thunderstorms and hail
• B. Continuous light rain and increased cloud cover
• C. Strong winds and abrupt temperature changes
• D. Clear skies and high visibility

Answer: (B)

The presence of a warm front typically leads to characteristics such as continuous light rain and increased cloud cover. When a warm front approaches, warm, moist air is lifted over cooler air, leading to the gradual ascent of the warmer air. This process generally results in the formation of stratus clouds, which can produce prolonged, steady precipitation rather than the severe weather often associated with cold fronts, like heavy thunderstorms or hail. As the warm front moves in, the cloud cover thickens, and the rainfall tends to be gentle but can persist for a longer duration. Therefore, the description of continuous light rain and increased cloud cover accurately reflects what you would expect when a warm front advances, supporting its identification as the correct response.
