TH E MAP ROOM THE IMPACT OF A SPLIT-FRONT RAIN BAN D ON APPALACHIAN COLD-AIR DAMMING EROSION BY MICHAEL J. BRENNAN, GAR Y M. LACKMANN, AND STEVEN E. KOC H split cold front is a cold front in the midtropo- sphere—usually centered near the 700-hPa A level—that is located at least 200 km ahead of the surface cold front, creating a forward-tipped cold front structure. This structure has been shown to fa- vor the development of convective precipitation along the upper-level cold front due to a thermally direct frontogenetical circulation that can provide the trig- ger for convective initiation. The split front is usually marked by a rapid decrease in moisture aloft during its passage, more so than temperature, so quantities FIG. I . Geographic features of Nort h Carolina and sur- such as 700-hPa equivalent-potential temperature (<9) rounding areas. or wetbulb potential temperature ( 0 ) are best to use for identification of a split front.
