NSERC / Hydro-Quebec Industrial Research Chair in short-term forecasting of precipitation: Phase II

魁北克水电公司是北美领先的公用事业公司，水力发电和配电是其运营的最重要方面。水力发电的有效发电和分配取决于对水库和流域流入量的准确预测，而这又受到降水类型和数量预测质量的重大影响。在工业研究主席计划的第一阶段，已经开发了各种工具，以改善预测的时间，地点，多少，什么类型的降水将发生在一至两天的提前时间。 在第二阶段，这一预测提前期将增加到一周，这将非常有利于 ** 水力发电的容量管理。NSERC/Hydro-Quebec Chair第二阶段研究计划的目标是，通过利用第一阶段获得的工具和结果，改进7天的降水预报。主要的重点是制定一个统一的跨模型分辨率的气溶胶微物理学多矩方案，并改进覆盖整个地球仪的加拿大计算机天气预报模型中对流的表示。另一个重点是评估全球和区域尺度上的定量降水和水文预报，因为它更好地代表了对流和云和降水过程。 预计该研究计划将提高降水预测，从而在水电容量管理中产生显着的经济效益。拟议的计划还将为麦吉尔学员，魁北克水电科学家和加拿大环境研究人员之间的合作研究保持一个激励的环境。

Hydro-Quebec is a leading utility company in North America and hydro-electric power generation and distribution is the most significant aspect of her operation. The efficient generation and distribution of hydro-electric power depends on accurate forecast of inflows in reservoirs and drainage basins, which in turn is affected significantly by the quality of the forecast of the type and amount of precipitation. During the first Phase of the Industrial Research Chair program, various tools have been developed to improve the forecast of when, where, how much, and what type of precipitation would occur over a lead time of one to two days. During Phase II, this forecast lead time will be increased to one week which would be highly beneficial for**capacity management of hydroelectric power.**The objective of the research program for the NSERC/Hydro-Quebec Chair in Phase II is to improve precipitation forecasts up to 7 days by building on the tools and results obtained during Phase I. The key focal point will be to develop a unified aerosol-microphysics multi-moment scheme across model resolutions, and to improve the representation of convection in the Canadian computer weather prediction model covering the whole globe. Another focus is to evaluate the quantitative precipitation and hydrological forecast over global and regional scales as a result of the better representation of convective and cloud and precipitation processes. It is anticipated that the research program would improve the prediction of precipitation, resulting in significant economic benefits in capacity management of hydroelectric power. The proposed program will also maintain a stimulating environment for collaborative research between McGill trainees, Hydro-Quebec scientists, and Environment Canada researchers.
