What type of chart provides a forecast of atmospheric conditions over specific periods?

Prog chart
Surface analysis chart
Radar summary chart
Satellite imagery chart

The correct answer is: Prog chart

A prog chart, also known as a prognostic chart, is specifically designed to provide forecasts of atmospheric conditions for future time intervals. It reflects predicted weather patterns over specified periods, which can include various aspects such as pressure systems, temperatures, precipitation, and wind patterns at different altitudes. This makes the prog chart a crucial tool in aviation for planning and executing flight operations since it presents an overview of expected weather developments. The other choices – surface analysis charts, radar summary charts, and satellite imagery charts – serve different purposes. Surface analysis charts depict the current weather conditions over a specific area, including fronts and significant weather phenomena. Radar summary charts provide real-time information about precipitation and storm intensity based on radar data but do not forecast future conditions. Satellite imagery shows cloud cover and other atmospheric features from satellite captures at a particular moment. Therefore, none of these options provide the forecast necessary for understanding future atmospheric conditions like the prog chart does.
