Graphical display method for marine meteorological safety early warning

The invention discloses a graphical display method for marine meteorological safety early warning. The method includes the steps: obtaining sea wave height forecasting and early warning information and wind field wind speed forecasting and early warning information of a target sea area; according to an electronic map of the target sea area, mapping the sea wave height forecasting and early warninginformation and the wind field wind speed forecasting and early warning information of the target sea area to corresponding positions of the electronic map; dividing the wind field wind speed into aplurality of wind speed grades, and setting corresponding colors for the wind speed grades; and mapping the colored wind speed grade information to the electronic map. According to the invention, thewind speed of the wind field is colored, so that a worker can determine the wind speed of the wind field everywhere in the target sea area more visually; and the sea wave height information and the wind field wind speed informa
