Precipitation nowcasting is of great importance for weather forecast users, for activities ranging from outdoor activities and sports competitions to airport traffic management. In contrast to long-term precipitation forecasts which are traditionally obtained from numerical models, precipitation nowcasting needs to be very fast. It is therefore more challenging to obtain because of this time constraint. Recently, many machine learning based methods had been proposed. We propose the use three popular deep learning models (U-net, ConvLSTM and SVG-LP) trained on two-dimensional precipitation maps for precipitation nowcasting. We proposed an algorithm for patch extraction to obtain high resolution precipitation maps. We proposed a loss function to solve the blurry image issue and to reduce the influence of zero value pixels in precipitation maps.

Skillful Precipitation Nowcasting using Deep Generative Models of Radar
Met Office(英国气象局)
降水临近预报,即提前两小时对降水进行高分辨率预报,支持许多依赖天气决策的部门的现实社会经济需求。国家的最先进的业务临近预报方法通常平流降水场与雷达为基础的风估计,并努力捕捉重要的非线性事件,如对流启动。最近引入的深度学习方法使用雷达直接预测未来的降雨率,不受物理限制。虽然它们准确地预测了低强度降雨,但它们的业务效用有限,因为它们缺乏约束,在较长的提前时间内产生模糊的临近预报,在更罕见的中到大雨事件中表现不佳。为了解决这些挑战,我们提出了一个深生成模型的概率临近预报雷达降水。我们的模型在长达1536 km x 1280 km的区域内产生现实和时空一致的预测,提前5 - 90分钟。在英国气象局50多位专家预测员的系统评估中,我们的生成模型在88%的情况下与两种竞争性方法相比,其准确性和实用性排名第一,证明了其决策价值和为现实世界专家提供物理见解的能力。当定量验证时,这些临近预报是熟练的,而不是诉诸模糊。我们表明,生成式临近预报可以提供概率预测,提高预测值和支持业务效用,并在决议和交货期的替代方法的斗争。
