The motivation for this note first arose during a discussion of the original article among members of the Convective Storms Group at NC State University (including Matt Morin, Casey Letkewicz, and Adam French), who also provided an initial review of the note. The author thanks Todd Lane, Dave Ahijevych, and Dick Johnson for directing him to some of the papers reviewing tropical values of CAPE. The three Darwin soundings in Fig. 1 and Table 2 were retrieved from the archive maintained by the University of Wyoming. The author’s effort in preparing this note was partly supported by the National Science Foundation under Grant ATM-0758509.
