09. Research on fog forecast on the sea of Quang Ninh - Hai Phong

Abstract

Monitoring data at Co To, Cua Ong, Bach Long Vy, Hon Dau stations at the sea of Quang Ninh - Hai Phong and GFS model data from 2014 - 2019 were used for building a 24-hour fog prediction equation, using a multi-dimensional regression function for months 1, 2, 3, 4 and 12. The results of the research and evaluation forecast on the dependent and independent data series showed that the forecast equations for January, February and March at Co To, Cua Ong and Bach Long Vy stations were selected to recommend forecasting the occurrence of fog at the Northeast Hydrometeorological Central with percentage of satisfactory forecasts ≥70 % and unsatisfactory forecasts FAR≤0.5. At Hon Dau station, only 2 forecasting equations for February and March satisfying the above two conditions were selected to recommend forecasting.
