    1. Grotjahn 1996a (0.9 Mb pdf file) This paper shows the evolution of 27 different troughs before and during cyclogenesis. It shows the upper and lower troughs are always both separate and have no upstream tilt prior to onset of development, a key point in showing that large nonmodal growth does not occur in the atmosphere since the necessary trough tilts are not observed.
    2. Grotjahn 1996b (1.5 Mb pdf file) This paper shows horizontal patterns at several levels of all the terms in the complete vorticity equation. The figures illustrate how the terms interact to maintain an upstream tilt of the trough axis, how the magnitudes compare, how energy for growth is distributed vertically, etc. One note: figures 5 and 6 are labeled as 'schematic' but in fact all the quantities depicted on them are traced from raw plots of the composite fields.
