Abstract

Weather Radar provides real-time, spatially and temporally continuous precipitation data over a large area, and therefore it has been used for operational hydrology in Canada over the past decades. Recently, the focus on weather Radar in Canada has increased since the existing Environment and Climate Change Canada (ECCC) C-band Radar network is replaced with S-band dual-polarized Radar. This paper aims to provide a wide-ranging literature review of the current Radar network in Canada and how it has been applied from a hydrological context. The review starts with an overview of the Canadian weather Radar network, emphasizing current and future developments. Next, the application of weather Radar in hydrology is summarized, including specific research and operational examples. Finally, some recommendations are provided for future studies based on new developments in Canada's weather Radar network.

摘要

天气雷达可提供大面积实时、空间和时间连续的降水数据，因此在过去几十年中，它已被用于加拿大的业务水文学。最近，由于现有的加拿大环境与气候变化 (ECCC) C 波段雷达网络被 S 波段双极化雷达取代，加拿大对天气雷达的关注有所增加。本文旨在对加拿大当前的雷达网络及其如何从水文环境中应用提供广泛的文献综述。审查首先概述了加拿大天气雷达网络，强调了当前和未来的发展。接下来，总结了天气雷达在水文中的应用，包括具体的研究和操作实例。最后，
