Precipitation in shallow convection over the Southern Ocean

该项目旨在量化南大洋的降水量，并查明导致其发展的关键动力和微物理过程。降水的频率和强度存在很大的不确定性，这限制了对耦合的南大洋气候系统进行模拟的能力。澳大利亚海洋研究船RV Investigator的观测显示，锋面之间常见的浅对流中出现了强降水事件，卫星观测或数值模型都没有捕捉到这些事件。该项目将改进天气预报，包括南大洋和毗邻的南极以及澳大利亚南部的降水和气候预测。

This project aims to quantify the amount of precipitation over the Southern Ocean and identify the key dynamical and microphysical processes that lead to its development. Large uncertainties exist in the frequency and intensity of precipitation, which limits the ability to model the coupled Southern Ocean climate system. Observations from the RV Investigator, an Australian marine research vessel, have revealed heavy precipitation events within the shallow convection commonly found between fronts that have not been captured by either satellite observations or numerical models. This project will improve weather forecasts, including precipitation, and climate projections over the Southern Ocean and the adjoining Antarctic and the southern part of Australia.
