Definition: Synoptic scale weather is a term applied to large scale weather systems. Large scale systems spanning several hundred to several thousand kilometers are part of the synoptic scale. Typical weather studied on the synoptic scale are tropical cyclones including hurricanes and typhoons.
Each time you watch your local weather forecast, you are seeing synoptic scale meteorology. Air masses and high and low pressure systems are also synoptic in scale.
