What atmospheric conditions are typically associated with strong winds and closely spaced isobars?

• A. Calm and hazy
• B. Gusty and variable
• C. Strong and steady
• D. Light and shifting

Answer: (C)

The correct answer is associated with strong winds and closely spaced isobars, which indicate a significant pressure gradient. In meteorology, isobars are lines on a weather map that connect points of equal atmospheric pressure. When these lines are closely spaced, it signifies a steep pressure gradient, leading to stronger winds as the atmosphere attempts to equalize the pressure difference. In this context, "strong and steady" captures the essence of what happens when closely spaced isobars are present. The airflow becomes more consistent and sustained, rather than variable or light. Strong winds can be experienced in such conditions due to the force exerted by the pressure gradient, which is why pilots and meteorologists pay close attention to isobar spacing when predicting wind strength and behavior. The other potential choices reflect different conditions that do not align with the presence of closely spaced isobars; for instance, calm and hazy weather typically implies a lack of wind and a flat pressure gradient. Gusty and variable conditions indicate a lack of consistency in wind speed and direction, typically associated with less stable atmospheric conditions. Light and shifting winds suggest a weak pressure gradient, which is precisely what closely spaced isobars would not represent. Thus, "strong and steady" is the correct characterization
