Heavy rainfall

This study aims to evaluating characteristics of rainfall simulated by Non–Hydrostatic Regional Climate Model (NHRCM) over seven sub–regions of Vietnam during the 1981–2001 period. Features such as seasonal cycle of monthly average daily rainfall, maximum daily rainfall, and frequencies at different thresholds are compared with observations.

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.

Real-time monitoring of quantitative precipitation distribution is essential to prevent natural disasters caused by heavy rainfall. This paper describes each process to introduce this QPE method to Viet Nam and indicates the results through the project. Future issues to improve its accuracy are also mentioned.

We developed a prototype system of the very short-range forecast of precipitation in Vietnam by merging kinematic extrapolations of composite hourly rainfall analysis and NWP, verified its performance for the case of a heavy rainfall event in July 2021 over central Vietnam.

The results indicate a statistically significant increase in extreme rainfall at the expense of light, moderate, and heavy rainfall over time. The only negative relationship is found in dry days. The most statistically significant trends exist in the 99th percentile, maximum, and R100 parameters with p-values of 0.07, 0.08, and 0.11, respectively

Objectives of research: 1) To explore mechanism of the seasonal moisture transport in Vietnam. 2) To determine the relationship between the moisture transport and the ENSO event, especially in ENSO years which heavy rainfall or severe drought occurred in Vietnam. 3) To propose the application of the moisture transport information for monitoring droughts (during El Niño) and heavy rainfall (during La Niña) over Vietnam.

Every year, the damages, caused by the natural disasters such as heavy rainfalls, floods and doughts ..., take lives and destroy properties in many parts of the world. In water resources engineering, frequency analysis is one of the statistical techniques applied by hydrologists to try and estimate the probabilities associated with design events.
