synoptic scale
Quick Summary
Synoptic meteorology is a branch of meteorology that uses observations and charts to study, diagnose, and forecast weather. The synoptic scale refers to weather phenomena that span distances of a few hundred to a few thousand kilometers and last for a few days to several days. These phenomena include migrating cyclones and anticyclones, which are responsible for daily weather changes. The concept of scale in meteorology categorizes phenomena by their size and duration, with the synoptic scale being larger and longer-lived than mesoscale phenomena but smaller and shorter-lived than planetary-scale phenomena. Synoptic weather maps, which display simultaneous observations for a large region, are a key tool in this field.123
