What is a cold front?

• A. It signals warm, dry conditions.
• B. It indicates an approaching warm front.
• C. It is associated with long periods of steady rain.
• D. This type of weather front brings a short period of heavy precipitation.

Answer: (D)

A cold front is a boundary where cold, dense air advances into warmer air, forcing the warmer air to rise rapidly. That quick lifting leads to condensation and often convective rain showers, which can be fairly intense. Because the front moves through relatively quickly, this precipitation tends to be short-lived, sometimes accompanied by thunderstorms and gusty winds. After the front passes, temperatures drop and winds shift. This pattern matches a brief, heavy rain event rather than warm, dry conditions or long, steady rain, so a short period of heavy precipitation is the best description.
