A Regional Arctic Ocean and Sea Ice Model with JRA-55 forcing, 2010-2015

The model used in this study is a regional coupled sea ice-ocean model based on the Massachusetts Institute of Technology general circulation model (MITgcm). This Arctic ocean/seaice model was applied to study the flow of water from the Chukchi Sea into the Arctic Ocean. This is motivated by the recently discovered Chukchi Slope Current. The model reproduces the observed flow across the shelf, through Barrow Canyon, and the westward-flowing Chukchi Slope Current. Mass, heat, and salt fluxes are diagnosed, pathways and the seasonal cycle are identified. Source code modifications, forcing fields, input files, and various scripts are provided to run the MITgcm and produce model fields used in publication Leng, H., M. A. Spall, R. S. Pickart, P. Lin and X. Bai, 2021: Origin and fate of the Chukchi Slope Current using a numerical model and in-situ data. J. Geophys. Res., 126, e2021JC017291. https://doi.org/10.1029/2021JC017291. This work was carried out at the Woods Hole Oceanographic Institution during 2020.

本研究使用的模型为基于麻省理工学院通用环流模型（Massachusetts Institute of Technology General Circulation Model，MITgcm）构建的区域海冰-海洋耦合模型。该北极海洋-海冰模型被应用于探究楚科奇海海水汇入北冰洋的流动过程。本研究的动机源于近期被发现的楚科奇斜坡流（Chukchi Slope Current）。该模型成功复现了观测到的陆架跨流、穿过巴罗峡谷的流场，以及向西流动的楚科奇斜坡流。研究诊断了质量、热量与盐度通量，明确了该流系的流动路径与季节循环特征。为运行MITgcm并生成本研究发表论文"Leng, H., M.
