This project aims to employ targeted field observations, numerical simulations and new satellite capabilities to identify the dynamical and microphysical mechanisms that enhance and redistribute precipitation across the alpine regions of south eastern Australia and Tasmania. These observations will be used to evaluate operational numerical weather simulations specifically focusing on quantitative precipitation forecasts and estimates. The observations will also be used to extend known biases in the national gridded precipitation analysis that are a result of the complex mountain terrain. This identification of the physical processes that enhance and redistribute precipitation over the alpine regions across south east Australia and Tasmania will lead to better precipitation estimates and forecasts and better water management.

该项目的目的是利用有针对性的实地观测、数值模拟和新的卫星能力，以确定在澳大利亚东南部和塔斯马尼亚的高山地区增加和重新分配降水的动力学和微物理机制。这些观测结果将用于评估业务数值天气模拟，特别侧重于定量降水预报和估计。观测结果还将用于扩大国家网格化降水分析中因复杂山区地形而产生的已知偏差。这种识别的物理过程，增强和重新分配降水在整个澳大利亚东南部和塔斯马尼亚州的高山地区将导致更好的降水估计和预测和更好的水管理。
