Featured Surface Analysis Map

Current Surface Analysis
The Current Surface Analysis map shows current weather conditions, including frontal and high/low pressure positions, satellite infrared (IR) cloud cover, and areas of precipitation. A surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations.

Mixed Surface Analysis
The Mixed Surface Analysis map shows a comprehensive analysis of current conditions and fronts at ground level using radar and infrared satellite imagery.

A surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations. Weather maps are created by plotting or tracing the values of relevant quantities such as sea level pressure, temperature, and cloud cover onto a geographical map to help find synoptic scale features such as weather fronts.

Occluded cyclone example. The triple point is the intersection of the cold, warm, and occluded fronts.

Surface weather analyses have special symbols which show frontal systems, cloud cover, precipitation, or other important information. For example, an H may represent high pressure, implying good and fair weather. An L on the other hand may represent low pressure, which frequently accompanies precipitation. Various symbols are used not just for frontal zones and other surface boundaries on weather maps, but also to depict the present weather at various locations on the weather map. Areas of precipitation help determine the frontal type and location.
