System and method for forecasting development trend of enteromorpha prolifera in Yellow Sea under combined action of physics and ecology

Abstract

The invention provides a Yellow Sea Enteromorpha development trend forecasting system and method under the physical and ecological combined action, and the system comprises the steps: firstly downloading external forced data and Enteromorpha satellite remote sensing data; performing calculation and prediction according to external forced data, enteromorpha satellite remote sensing data, enteromorpha drift calculation parameters under the action of multi-scale airflow and enteromorpha growth and death calculation parameters under the action of a biochemical process to obtain forecast data of a Yellow Sea enteromorpha drift transport path and biomass scale change under the combined action of geobiochemistry; and finally, based on forecast data, processing and visually displaying information such as a drift path, biomass, a distribution area and shore abutting moment early warning of the Yellow Sea enteromorpha particles. Therefore, according to the implementation mode, the forecasting timeliness can be improved through the web crawler and automatic forecasting, and the forecasting accuracy of the drifting rate, the drifting direction and the biomass forecasting elements of the enteromorpha prolifera in the Yellow Sea can be improved by considering the turbulent flow small-scale motion random process and the biochemical process of various nutritive salts.

Description

technical field [0001] This application relates to the field of physical ocean and marine ecological dynamics, and specifically relates to a system and method for forecasting the development trend of Enteromorpha in the Yellow Sea under the joint action of physical ecology. Background technique [0002] From April to August every year, a large-scale green tide disaster with Enteromorpha as the dominant species will break out in the central and southern waters of the Yellow Sea. In the prior art, the numerical simulation of the drift transport of Enteromorpha phytoplankton in the sea is mainly based on the posterior simulation of the transport of Enteromorpha phytoplankton in the Yellow Sea based on the Lagrangian method (that is, for the past outbreaks of Enteromorpha time for numerical simulation). However, it has been found in practice that this method has the problems of poor forecast timeliness and low resolution of ocean current driving. Contents of the invention ...
