Surface analysis charts serve a crucial role in meteorology by providing a snapshot of current weather conditions across a specific region at a given time. These charts depict features such as pressure systems, fronts, and temperature gradients, which are essential for understanding atmospheric dynamics.

One significant purpose of these charts is to help meteorologists and dispatchers locate the jet streams and turbulence that can affect flight performance. The jet stream, which is a fast-flowing air current high in the atmosphere, often interacts with surface weather patterns and can cause significant turbulence. By analyzing surface analysis charts, dispatchers can gain insights into where these turbulent areas might be located, allowing for better flight planning and enhancing safety for aircraft operations.

The other options, while related to aviation and meteorology, do not accurately reflect the primary function of surface analysis charts. Instead, these charts are not used for future weather predictions, tracking aircraft maintenance, or assessing runway conditions directly. Each of those aspects relies on different tools and data sources.
