Which chart shows current surface features?

• A. Prognostic chart
• B. Surface analysis chart
• C. Weather depiction chart
• D. Winds aloft chart

Answer: (B)

The main idea is identifying which chart presents real-time features at the Earth's surface. The surface analysis chart is designed to depict current surface conditions by plotting station observations (wind, temperature, dew point, pressure) and drawing isobars and frontal boundaries to show the positions of high and low pressure, fronts, and other surface weather features. It’s compiled from surface observations (METARs and other stations) and is updated regularly to reflect current conditions, making it the go-to for understanding what’s actually happening at ground level right now. The other charts serve different purposes: prognostic charts forecast future surface features, winds aloft charts show upper-level winds and temperatures, and the weather depiction chart focuses on overall current weather conditions and flight categories but not the explicit surface features like fronts and isobars.
