Abstract : Numerically analyzed baroclinicity, an operational product of Fleet Numberical Weather Facility (FNWF), Monterey, California, is related to cloud patterns depicted on ESSA III nephanalyses for the Atlantic-European and Pacific-North American areas during the period 7-17 December 1966. In addition, interrelations between the numerically analyzed fronts, satellite cloud observations and FNWF 850-mb and 500-mb vertical motion fields are presented. HYperbaroclinic zones are found to contain a greater percentage of clouds than areas outside these zones at all latitudes from 15-60 N. For instance, 61 percent (44 percent) of the average hyperbaroclinic zone in the Pacific-North American (Atlantic-European) area is covered by more than .5 clouds while only 30 percent (28 percent) of the adjacent quasi barotropic zones show similar cloudiness. The FNWF fronts and cloud bands are found most closely related, in orientation and intensity, in the dense-data Atlantic Ocean area. More clouds are found to occur in regions of ascent than in regions of descent, the ratio being 2 over land and 1.5 over ocean areas, but the correlation of vertical motion and percentage of cloud cover is not simple or necessarily positive.
