A Numerical Case Study of the Impact of Submesoscale Feedbacks on Mesoscale Eddies

Yunlong Fei, Shaoqing Zhang, Wei Zhao, Gang Li et autres

Understanding the impact of feedback of submesoscales on mesoscale eddies is critical to clarify the multiscale interactions in the ocean, yet it remains ambiguous. This study first designs a “twin” downscaled framework with two-way nesting that can control the feedback strength of …

Spatial and Seasonal Characteristics of the Submesoscale Energetics in the Northwest Pacific Subtropical Ocean

Yunlong Fei, Shaoqing Zhang, Kaidi Wang, Yangyang Yu et autres

The spatial and seasonal characteristics of submesoscales in the Northwest Pacific Subtropical Ocean are thoroughly investigated here using a submesoscale-permitting model within a localized multiscale energetics framework, in which three scale windows termed background, mesoscale, and submesoscale are decomposed. It is found …

Multiscale energetics and submesoscale instabilities of eddy shedding at the Kuroshio loop current in the South China Sea

Yunlong Fei, Shaoqing Zhang, Zhengguang Zhang, Yang Gao et autres

The multiscale energetics and submesoscale instabilities after the eddy shedding of Kuroshio Loop Current (KLC) intrusion into the South China Sea (SCS) remain ambiguous. Here, a typical KLC eddy shedding process is well simulated using a downscaled submesoscale-permitting model. Then, energy and …

Evaluating statistical consistency for the ocean component of earth system models using physics informed convolutional autoencoder

Yangyang Yu, Shaoqing Zhang, Haohuan Fu, Dexun Chen et autres

Model verification is a crucial step in the development and optimization of Earth system models (ESMs). Recently, a deep learning approach in evaluating statistical consistency for the atmosphere component of ESMs (A-ESM-DCT) has been proven effective in model verification. However, due to …

Kilometer-Level Coupled Modeling Using 40 Million Cores: An Eight-Year Journey of Model Development

Xiaohui Duan, Yuxuan Li, Liu Zhao, Bin Yang et autres

With current and future leading systems adopting heterogeneous architectures, adapting existing models for heterogeneous supercomputers is of urgent need for improving model resolution and reducing modeling uncertainty. This paper presents our three-week effort on porting a complex earth system model, CESM 2.2, …

Toward Earth system modeling with resolved clouds and ocean submesoscales on heterogeneous many-core HPCs

Shaoqing Zhang, Shiming Xu, Haohuan Fu, Lixin Wu et autres

With the aid of the newly developed 'Sunway' heterogeneous-architecture supercomputer, which has world-leading HPC (high-performance computer) capability, a series of high-resolution coupled Earth system models (SW-HRESMs) with up to 5 km of atmosphere and 3 km of ocean have been developed. These …
