## ECS2_DModel

The model uses the two-dimensional shallow water equation in the spherical coordinate system as the governing equation, and the simulation range is 117.5. E-131. E, 23.6. N-41.7. N, the space step is 0.1. That is, each grid is divided into 10 grid units. Except for the natural coastline, the boundary is: the east coast of Fujian Province to the west coast of Taiwan, the southeast is bounded by the Ryukyu Islands, and the northeast is the opposite of the Strait. Boundary.

#### Model Description

English {{currentDetailLanguage}} English

The open boundary conditions of the model are specified in the middle and late September of 1992. The simulation can be continued for more than 20 days. In addition to the simulation calculation of the stability process in the first three days, the effective data can be simulated for half a month, supplemented by tidal harmonic analysis. The main tidal wave characteristics of the East China Sea, and further study the impact of shoreline changes on the tidal wave system in different historical periods, and provide boundary conditions for the three-dimensional dynamic mechanism of the formation and evolution of the radiation sandbars outside Jiangsu.

Therefore, the open boundary of the simulation system is specified. The file that the user needs to input is jwd.txt, that is, the latitude and longitude coordinates of the output point. The format is: longitude, longitude, longitude, second (long line), latitude, latitude, latitude and second. The output file is CWLIUSU.OUT in the format: time (hours) tidal level (m) east flow rate (m/s) north direction flow rate (m/s).
