英文摘要 |
The purpose of this project is to maintain forecasting systems to facilitate daily
forecast of air quality over the Taiwan area. The main works include: Maintain and operate
the numerical forecasting model, the China dust dynamic numerical model
(TAQM/KOSA;WRFDUST), local dust dynamic model (TAQM/TWKOSA), Taiwan Air
Quality Model (TAQM), Community Multi-scale Air Quality (CMAQ) Model and
mesoscale numerical weather prediction system (MM5 and WRF) included. Analyze the
characteristic of atmospheric factors, ozone and PM2.5 between the model simulated
results, site monitoring data and MODIS satellite retrieval data. The results will feedback
to as the references to modify the relative dynamic numerical model in the future. In the
part of seriously polluted events analysis, two cases focusing on high level haze events
were completed. For the reason of dust from riverside, using statistical analysis to figure
out the correlation among the factors of environment, weather and river. Provide
special-duty manpower to organize, integrate all of the information to offer the referral for
the EPA air quality pre-warning decision and supporting the organization learning of EPA.
Project coordinate director join the Mainland China dust event forecasting examining
meeting and provide the expert opinion to EPA.
The main modified of operation models are to upgrade the CMAQ V4.6 to V4.7,
using WRF instead of MM5 for air quality and local dust models and provide the
WRF2MM5 conversion program for the TAQM/TWKOSA and ultraviolet ray forecasting
project. Increasing the WRFDUST model to joined as one member of the operation models.
Air quality auxiliary forecast system is modified to increase the function of forecasting the
PM2.5 from 1st Oct. 2014.
