The synoptic chart is similar to a topographical chart where it shows the variation in atmospheric pressure over the Earth’s surface. Long-wave ridges build as a major short-wave ridge, confluent flow, or WAA moves into the crest of the long-wave ridge. 23° 1. and … The synoptic scale in meteorology (also known as large scale or cyclonic scale) is a horizontal length scale of the order of 1000 kilometers (about 620 miles) or more.
