Synoptic meteorology

Synoptic Meteorology refers to viewing large-scale horizontal weather patterns of the order of 1,000 km or more at a common point in time.[1] Typically, weather maps contain information regarding synoptic-scale systems, such as areas of high- and low- pressure, extratropical cyclones, and their associated fronts. When these different components and parameters of the atmosphere are viewed together, large-scale weather patterns emerge. The presence of large-scale weather patterns aid in determining the weather conditions that may occur at a local scale.

Meteorologists utilize surface analysis and upper-air analysis to visualize synoptic-scale systems and aid in weather forecasting. Combinations of surface and upper-air maps inform the forecaster to the presence, intensity, and trajectory of large-scale weather systems and their associated components.
