Large Scale Simulation Research Laboratory National Electronics and Computer Technology Center, National Science and Technology Development Agency Large Scale Simulation Research (LSR) laboratory is a part of National Electronics and Computer Technology Center (NECTEC), National Science and Technology Development Agency (NSTDA). LSR try to build capacity to perform large scale computer simulation with the aim to solve high impact problems.
“To understand, innovate and manage problems through computer simulations.”
Responsibility: Research Assistant (2 September – 20 December 2013) “Accuracy and Precision Evaluation of Rainfall in Thailand from the Weather Research and Forecasting (WRF) Model,” in collaboration with Hydro and Agro Informatics Institute (HAII.) Background & Importance
Results & Outcomes
Rainfall is one of the most important factor that influence many of natural disasters such as severe flood, landslide, and riverbank erosion. Weather forecasting is thus an essential tool to predict the rainfall and operate the rainfall warning system.
Accuracy and precision of the WRF-forecasted rainfall in Thailand has been statistically evaluated, which represent the interspecific differences between regions and seasons. The results will be used by LSR to improve the WRF model and by HAII to develop the rainfall warning system.
“Accuracy and Precision Evaluation of the WRF Model is needed in order to access its reliability of rainfall.”
“HAII’s warning system is an outstanding mechanism in Thailand water management driven by the WRF model.” summer

Statistical Visualization Box-whisker plots visualize the Critical Success Index (CSI), a statistical value used to evaluate the temporal reliability of the forecasted rainfall in various regions and seasons.
In Situ Observation Observational rainfall data measured by 540 meteorological stations deployed across Thailand were used to evaluate the spatial reliability of the forecasted rainfall from the WRF model especially in the high risk areas and the monsoon season.
Science is the fundamental law of the universe. It does not matter how reliable the model is, at least, we have put our effort into understanding nature.
