Summary: | In an earlier paper (Model Atmospheres (I)), a procedure was developed for determining the most probable vertical temperature profile associated with the occurrence of 1% global temperature extreme at mandatory-pressure levels at stations in North American Arctic. The same technique, based upon a variation of the stepwise multiple regression procedure was employed in the current study. Whereas the radiosondes investigated in Model Atmospheres (I) consisted entirely of "checked-data" quality, those stations desiagnated for study in this work required a much more refined data-screen, due to lack of initially checked radiosonde report quality. Nevertheless, after application of various acceptability criteria, the radiosondes at each station were arranged in the same format as employed in Model Atmospheres (I). There remained in each case a suitable sample population to provide significant results. The ensuing multiple regression analysis applied to the geographically and climatologically diverse set of stations of the current study led to realistic estimates of the temperature profiles which were conditionally dependent upon the existence of 1% extreme forcing-level temperature TJ at previously designated pressure levels PJ.
