Ask The Weatherman for April 30, 2013:
Question: What is meant by the term zonal flow?
Answer: When we talk about zonal flow, we are talking about the jet stream. The jet stream is found at between 20-30,000ft. When the jet stream is in a zonal flow pattern that means that it is flowing straight west to east across the sky, like from California to Kansas as an example.
