Short summary
Simulating how chemical species are advected by air flow is essential for air quality and climate research, but becomes prohibitively slow when hundreds of species are tracked at high resolution. We developed a new transport method that removes the most costly step in current approaches. Tests show it matches existing accuracy while achieving nearly 4-fold computational speedup. The design is transferable to other models, offering a pathway toward faster high-resolution atmospheric simulations.

Improving climate predictions has significant socio-economic impacts. In this study, we develop and apply a new weakly coupled ocean data assimilation (WCODA) system to a coupled climate model. The WCODA system improves simulations of ocean temperature and salinity across many global regions. This system is meant to advance our understanding of the ocean's role in climate predictability.

Improving climate predictions have profound socio-economic impacts. This study introduces a new weakly coupled land data assimilation (WCLDA) system for a coupled climate model. We demonstrate improved simulation of soil moisture and temperature in many global regions and throughout the soil layers. Furthermore, significant improvements are also found in reproducing the time evolution of the 2012 US Midwest drought. The WCLDA system provides the groundwork for future predictability studies.

C-Coupler3.0 is an integrated coupler infrastructure with new features, i.e. a series of parallel-optimization technologies, a common halo-exchange library, a common module-integration framework, a common framework for conveniently developing a weakly coupled ensemble data assimilation system, and a common framework for flexibly inputting and outputting fields in parallel. It is able to handle coupling under much finer resolutions (e.g. more than 100 million horizontal grid cells).

Short summary
Short summary
All global climate models (GCMs) use the grid-averaged surface heat fluxes to drive the atmosphere, and thus their horizontal variations within the grid cell are averaged out. In this regard, a novel scheme considering the variation and partitioning of the surface heat fluxes within the grid cell is developed. The scheme reduces the long-standing rainfall biases on the southern and eastern margins of the Tibetan Plateau. The performance of key variables at the global scale is also evaluated.

Short summary
Many atmospheric models use shallow approximation that work well when the model top is low. As models top now reach higher layers, these approximation need to be relaxed. We develop a deep atmosphere dynamical core(GMCORE), including full deep atmosphere dynamics, and spherical geometry. The tests case with idealized baroclinic waves and tropical cyclones show that the new model reproduces known results and can alter storm trajectory, suggesting value for future high-top and tropical studies.
Many atmospheric models use shallow approximation that work well when the model top is low. As...
