A pilot scheme to identify hottest days affecting the California Central Valley
from large scale upper air data. It also has additional interpretation of how
extreme heat develops there, with the 2006 event as an example.

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.
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.
