Achievement of JICA technical cooperation project in period 2

Japan International Cooperation Agency (JICA) and the Viet Nam Meteorological and Hydrological Administration (VNMHA) have implemented a technical cooperation project entitled “Project for Strengthening Capacity in Weather Forecasting and Flood Early Warning System” for more than 5 years from May 2018. In period 2 from April 2020 to the present, the project has achieved some outstanding achievements. Automatic Weather Station (AWS) inspection and calibration method was trained by using the procured traveling standards for temperature, humidity, pressure and precipitation at headquarters, Phu Lien and Vinh. An operational tentative quality control system was introduced to check temperature and precipitation data in near-real time. Quantitative precipitation estimation (QPE) product has been operationally calculated by combining radar and selected rain gauge data. Methods to distinguish qualified rain-gauge data from poor-qualified rain-gauge data were introduced. Precipitation guidance was developed and tested in several heavy rain cases. Short-range precipitation forecasting up to 15 hours has been developed by combining the kinematic extrapolation method and mesoscale numerical forecast. Webpage and mobile application were developed to monitor rainfall situations and related warnings.
