submesoscale modelling figures data at Changjiang River

This item shows submesoscale modelling figures data used at manuscript '<b>Tidal Modulation of Submesoscale Dynamics in the Yangtze River Estuary</b>'.The model domain spans the entire Yangtze River estuary (29.5°N-32°N, 120°E-124°E), with a horizontal resolution of approximately 1 km and 50 vertical coordinate levels. The simulation incorporates 16 tidal constituents and uses 6-hourly climatological atmospheric forcing from the European Centre for Medium-Range Weather Forecasts (ECMWF) operational model analysis as surface boundary conditions.The model is two-way nested from the climatological simulation of China's marginal seas described by Sun et al. (2019), which has been well-validated against various observational datasets. The monthly climatological mean discharges of the Yangtze River and Qiantang River are incorporated into the model. Following a 20-year spin-up, the model reached a state of equilibrium. To assess the effects of tidal forcing on submesoscale dynamics, we conducted two sets of simulations: one with tidal forcing and one without. The tidal and non-tidal analyses utilize hourly and daily outputs over the month of August, respectively.
