How does orography enhance precipitation in Australian wintertime storms?

该项目旨在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加强和重新分配降水的动力和微物理机制。这些观测值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。这些观测还将被用来扩大国家网格降水分析中的已知偏差，这些偏差是复杂山区地形的结果。确定在整个澳大利亚东南部和塔斯马尼亚高山地区加强和重新分配降水的物理过程将导致更好的降水估计和预报以及更好的水管理。

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.
