Which of these tells that there is an approaching storm? A. dark clouds and cold air B. gentle wind and rain showers C. strong winds and heavy rains
The correct answer and explanation is:
Correct Answer: A. dark clouds and cold air
Explanation (300 words):
Dark clouds and cold air are common early signs that a storm is approaching. These signs occur during the initial phase of storm development and are used by meteorologists and weather observers as indicators of changing atmospheric conditions. When you notice dark, thick clouds forming in the sky—especially cumulonimbus clouds—it often means that a thunderstorm or severe weather system may be forming. These clouds are capable of producing lightning, thunder, heavy rainfall, and sometimes hail or tornadoes.
In addition to dark clouds, the sudden arrival of cold air is another strong sign of an incoming storm. This temperature drop occurs because storms are often accompanied by cold fronts—boundaries between warm and cold air masses. As the cold front moves in, it forces warm air upward, which leads to condensation and cloud formation, eventually resulting in precipitation and potentially severe weather.
On the other hand:
- B. Gentle wind and rain showers usually indicate mild or passing weather systems, such as light rain or drizzle. These conditions are not typically associated with severe storms.
- C. Strong winds and heavy rains are signs that the storm has already arrived or is in progress, not necessarily an indication that one is approaching.
Understanding these early indicators helps in taking timely safety precautions. For example, when dark clouds and a sudden drop in temperature are observed, it’s wise to seek shelter or check weather updates for storm warnings. Being aware of these signs can significantly reduce the risks associated with severe weather events, especially in areas prone to thunderstorms, hurricanes, or other extreme weather patterns. Therefore, option A is the most accurate answer when looking for signs that a storm is approaching, rather than already occurring.
