Abstract Six recent Langmuir turbulence parameterization schemes and five traditional are implemented in a common single‐column modeling framework consistently compared. These tested scenarios versus matched large eddy simulations, across the globe with realistic forcing (JRA55‐do, WAVEWATCH‐III simulated waves) initial conditions (Argo), under as observed at ocean moorings. Traditional non‐Langmuir systematically underpredict simulation vertical mixing weak convective forcing, while vary...
Storm surge is one of the most significant marine hazards in coastal regions Fujian, China. Previous studies show that surface waves can exacerbate storm by providing additional momentum and mass flux. In fact, wave effects on currents be divided into conservative non-conservative parts. However, it unclear whether or not both kinds are important to surge. this study, we utilize an ocean circulation model coupled with forcing investigate caused Typhoon Doksuri (2305). The results indicate...
Abstract Langmuir turbulence, a dominant process in the ocean surface boundary layer, drives substantial vertical mixing that influences temperature, salinity, mixed layer depth, and biogeochemical tracer distributions. While direct resolution of turbulence climate models remains computationally prohibitive, its effects are commonly parameterized, frequently within established turbulent frameworks like K‐profile parameterization (KPP). This study utilizes modified KPP determines depth...
Chloroplastic m-type thioredoxins (TRX m) are essential redox regulators in the light regulation of photosynthetic metabolism. However, recent genetic studies have revealed novel functions for TRX m meristem development, chloroplast morphology, cyclic electron flow, and tetrapyrrole synthesis.

Compared with individual events, compound weather and climate extremes may impose more serious influences on natural systems human society, especially in populated areas. In this study, we examine the changes precipitation events that follow extremely hot within several days during 1961–2017 South China by taking Guangdong Province as an example. Additionally, assess impacts of urbanization these changes. It is found extreme are often preceded weather, average fraction 28.25%. The such even...
