Abstract A discussion is given of the justification and usefulness of analysing on isentropic charts observations of the flow relative to a mature large‐scale motion system under the assumption that the system is in a steady state. It appears that trade wind air may rise over a front into a jet stream and that by an extension of the parcel theory into three dimensions the speed of a jet stream may be related to an area on the aerological diagram.
