2009年2月7日，澳大利亚维多利亚州发生“黑色星期六”火灾，对当天的气象条件进行了调查。白天温度超过45°C，强烈的地面风和极端干燥的条件相结合，产生了有记录以来最严重的火灾天气条件。使用英国气象局统一模式和现有观测的高分辨率嵌套模拟来识别当天的重要中尺度特征。最高分辨率域的水平网格间距为444米，再现了观测到的气象条件的大部分方面。这些包括有组织的水平对流卷，下午晚些时候的强烈凉爽变化，具有许多不稳定重力流的特征，较弱的傍晚冷锋和传播的夜间钻孔。这些中尺度现象在短时间和空间尺度上引起风、温度和湿度的变化，这反过来又导致火灾危险的大的空间和时间变化。皇家气象学会
The meteorological conditions are investigated over the state of Victoria, Australia on 7 February 2009, the day of the ‘Black Saturday’ fires. Daytime temperatures exceeding 45°C, strong surface winds and extremely dry conditions combined to produce the worst fire weather conditions on record. A high‐resolution nested simulation with the UK Met Office Unified Model and available observations are used to identify the important mesoscale features of the day. The highest resolution domain has horizontal grid spacing of 444 m and reproduces most aspects of the observed meteorological conditions. These include organized horizontal convective rolls, a strong late‐afternoon cool change with many of the characteristics of an unsteady gravity current, a weaker late‐evening cold front and propagating nocturnal bores. These mesoscale phenomena introduce variability in the winds, temperature and humidity at short temporal and spatial scales, which in turn lead to large spatial and temporal variability in fire danger.
