The suggestion has been made that the Montgomery streamfunction is now calculable for isentropic analysis purposes simply by applying the equation Ψ = gZ + c p T . Historically, this practice has been frowned upon, as measurements aloft did not have the accuracy requisite to allow such practice. Instead, an integral approach to calculating Ψ has been preferred to get workable values. Yet, advancements in the accuracy of radiosonde measurements have occurred, especially with global positioning system ( GPS )‐verified height data. Herein, we show that the values from the simple and integral methods of getting Ψ are very similar, and differ by only ∼0.2%. © 2012 Royal Meteorological Society
