Which weather condition is characterized by a significant drop in temperature and rising winds?

• A. Heatwave
• B. Cold front
• C. Warm front
• D. Tropical storm

Answer: (B)

The condition characterized by a significant drop in temperature and rising winds is a cold front. A cold front occurs when a mass of cooler air moves into an area occupied by warmer air. As the cooler air advances, it forces the warmer air upwards, leading to a rapid decrease in temperature. This upward motion can cause increased wind speeds due to the contrasting air masses. The sharp temperature drop typically accompanies precipitation and possibly thunderstorms, contributing to the rising wind patterns associated with the passage of the cold front.

In contrast, a heatwave involves prolonged periods of excessively hot weather, while a warm front brings gradual temperature increases and often less turbulent conditions compared to cold fronts. A tropical storm is associated with high winds and heavy rain but does not solely signify a dramatic temperature drop. Understanding these dynamics is crucial in interpreting weather patterns and their implications for aviation operations.
