A formula for the instantaneous growth rate of vorticity waves was tested on 152 contour troughs and 101 contour wedges at the 500-millibar level. It was found that the formula could be used qualitatively for determining whether individual troughs and wedges will intensify or weaken over periods of 24 hours, without carrying out the laborious computations required by an exact application of the formula. Further examination of data showed that cut-off lows formed in pre-existing troughs most readily when the negative tilt of the troughs was greater than 15°, or strong asymmetry was present.
