Japan recently announced plans to discharge over 1.2 million tons of radioactive water from the Fukushima Daiichi Nuclear Power Plant (FDNPP) into Pacific Ocean. The contaminated can poses a threat marine ecosystems and human health. To estimate impact plan, here, we developed three-dimensional global model track transport dispersion tritium released FDNPP. pollution scenarios for four release durations (1 month, 1 year, 5 years, 10 years) were simulated. simulation results showed that in...
Abstract Improving intensity simulation and forecast of tropical cyclones has always been a challenge, although in recent years the track forecasts have remarkably improved. In this study, we explore sensitivity typhoon to three physical processes using fully coupled atmosphere‐ocean‐wave model. Two storms, strong weak one, chosen. The effects wave breaking induced sea spray, ocean vertical mixing associated with nonbreaking surface waves, cooling due intense rainfall are assessed by means...

Then, test platform set...
Abstract Tropical cyclones (TCs), especially landfalling intense storms often pose serious threats to life and property in coastal areas. Although TC track forecast skill has been improved the past decades, progress of advancing intensity lags that forecast. One possible limiting factor is absence ocean surface waves systems. To better represent interaction underlying ocean, a regional atmosphere‐ocean‐wave coupled model employed this study. Twenty‐one TCs whole year 2013 are retrospectively...

Negative downwind drag coefficient values begin occur speed approximately 4 m/s. Our results show that swells and nonstationary airflow...

Large-scale wind power grid integration will greatly change the system current distribution, making it difficult for reactive regulator to adjust optimal state. In this paper, an integrated optimisation method based on improved Harris Hawk (HHO) algorithm is proposed. Firstly, a regulation model constructed solve interval of turbines, and margin turbines used participate in system’s optimisation. Finally, compensation capacity allocation considering nodal voltage deviation, line loss...
The observed snow depth and ice thickness on landfast sea in Prydz Bay, East Antarctica, were used to determine the role of (a) annual cycle at a fixed location (SIP) where usually blows away after snowfall (b) early summer within transportation route surveys (TRS) domain farther from coast, accumulation is substantial. mean maximum had negative relationship (r = −0.58, p < .05) SIP, indicating primary insulation effect thickness. However, TRS domain, this was negligible because contributes...
Abstract Sea surface temperature (SST) data from the Copernicus Marine Environment Monitoring Service are assimilated into a pan-Arctic ice–ocean coupled model using ensemble-based local singular evolutive interpolated Kalman (LSEIK) filter. This study found that SST deviation between hindcasts and independent observations is reduced by assimilation. Compared with results without assimilation, has decreased up to 0.2°C at end of summer. The strongest improvements located in Greenland Sea,...
Abstract Waves critically modulate the air‐sea fluxes, and upper‐ocean thermodynamics in a Tropical Cyclone (TC) system. This study improves modeling of TC intensification by incorporating non‐breaking wave‐induced turbulence sea spray from breaking waves into an atmosphere‐ocean‐wave coupled model. Notably, wind forecast error decreased around 10% prior to TCs' peak intensity. The positive feedback along with compensatory negative waves, overall enhanced These wave‐coupled processes...
