Abstract:	研究期間：10102~10112;Heavy rainfall events often occur in the Tseng-Wen Reservoir watershed during Mei-yu fronts from May to June and typhoons from July to September. The existing Central Weather Bureau (CWB) Doppler radar and rain gauge network doesn’t cover this region well because of terrain blockage. Insufficient or contaminated radar observations lead to difficulties in rainfall estimation, and insufficient rain gauge observations result in considerable difference between regional rainfall estimation and the actual amount of the water reservoir intake. Therefore, this project plans to deploy the mobile dual-polarization Doppler radar, TEAM-R, in the Tseng-Wen Reservoir watershed for synchronized observations with CWB Cigu Radar. The goal is to enhance the ability of quantitative precipitation estimation in this region. The strategy of terrain echo distinguishment will be tuned to optimize terrain echo removal. Additional jobs include upgrading the radar data quality, improving the accuracy of rainfall estimation and calibration with in situ rainfall measurements. In general, this project aims at the benefit assessment of the weather radar observations in the Tseng-Wen Reservoir watershed.
