A fog forecasting system using weather satellite and fog forecasting method thereof

摘要

A fog forecasting system using weather satellite and a fog forecasting method thereof are provided to distinguish fog and low-level clouds by calculating Laplacian about luminance temperature distribution of the determined observation region, thereby increasing the accuracy of fog detection. A fog forecasting system using weather satellite comprises a stationary orbit meteorological satellite detecting he intensity of the near infrared ray and infrared ray radiated from the observation region, which is equipped with an observation sensor for the near infrared ray channel and an observation sensor for the infrared channel; a remote-sensing satellite detecting the sea-surface wind speed of the observation region by employing a sea-surface wind detecting sensor; a receiver of satellite signal received with the detected information from the stationary orbit meteorological satellite and remote-sensing satellite; and an analysis equipment presuming the fog generation region, which is equipped with an operator programmed with analysis algorithm and a memory stored with Laplacian boundary value/sea-surface wind speed of boundary value about luminance temperature difference boundary value/luminance temperature distribution.
