Profiles
Figure 2 Skew T - Melbourne Airport 0Z 9th January 2000 - 1100AEDST Courtesy of University of Wyoming This profile shows moderate lapse rate in the lower 3km. An inversion is located at 1030m and a moist layer between 707hPa (3035m) and 582hPa (4566m) conforms to the middle level cloud deck that was present at this time. Note the very marked drying out between 582hPa (4566m) and 474hPa (6132m). Humidity at 474hPa is shown as being 7%. Note the backing of the vertical wind flow.
Figure 3 Skew T - Geelong Airport 4Z 9th January 2000 (modified) - 1600AEDST Courtesy of Bureau of Meteorology - Severe Weather Section The modified Skew T for Geelong Airport shows a marked steepening of the lapse rate between the surface and 3km which becomes potentially superadiabatic. This has occurred while the FZL (freezing level) has remained virtually the same as the Melbourne airport 1100AEDST reading. A significant dry layer at 474hPa (6132m) has remained while moderately strong lapse rates continue between 474 and 300hPa.
