Which weather chart shows conditions forecast to exist at a specific future time?

• A. Surface Analysis Chart
• B. Constant Pressure Analysis Chart
• C. 12-hour Significant Weather Prognostic Chart
• D. Upper Air Analysis Chart

Answer: (C)

The 12-hour Significant Weather Prognostic Chart is specifically designed to display forecast conditions that are expected to occur at a specific future time, typically 12 hours ahead. This chart offers insights into expected weather patterns, including significant features such as areas of precipitation, storms, and other meteorological phenomena. In contrast, the other types of charts serve different purposes. For example, the Surface Analysis Chart provides a snapshot of current weather conditions rather than future forecasts, reflecting the present state of the atmosphere as observed from various locations. The Constant Pressure Analysis Chart mainly depicts atmospheric conditions at a fixed pressure level, showing how temperature, wind, and moisture behave at that specific altitude but is not geared towards forecasting specific future situations. Similarly, the Upper Air Analysis Chart presents current upper atmospheric conditions without a forecast component. Understanding the function of each type of chart helps in identifying the 12-hour Significant Weather Prognostic Chart as the appropriate tool for predicting upcoming weather conditions.
