Subtropical fronts observed during the 1996 Central Australian Fronts Experiment

摘要: The 1996 Central Australian Fronts Experiment (CAFE96) was the third in a series of field experiments designed to better understand structure and dynamics late dry-season subtropical cold fronts that affect central Australia. In this paper, behaviour three observed during CAFE96 are described detail four other occurred examined light previous studies. total, fourteen were documented experiments, which twelve crossed Australia evening or early hours morning. Only one afternoon (Event 4 CAFE96), only mid-morning 6 CAFE96). latter front arrived at Alice Springs and, as daytime turbulent mixing increased, it ceased advancing northeastward retrogressed. It subsequently retreated through Springs, giving way strong northwesterly winds blowing dust. reversed direction once again station 70 km southeast mid-afternoon. While is probably quite common for position oscillate back forth waxes wanes, Event first example be detail. 3 more typical two but discussed briefly here because best date exhibiting near-surface warming strip following passage front. This detected satellite imagery confirmed by surface measurements.
