The impact of zonally symmetric and asymmetric climates on tropical cyclone genesis in coupled Aqua and Ridge Planets

Tropical cyclone genesis and development largely depend on the conduciveness of the large-scale environment. We demonstrate the impact of zonal asymmetry on tropical cyclone genesis magnitude and distribution using two idealized coupled climate models. We first examine a zonally symmetric configuration, “Aqua”, which is a water-covered planet without land except for two polar caps. We then break the zonal symmetry by introducing a single grid-cell-wide strip of idealized continent between the two polar caps on “Ridge\". The coupled CESM configurations in this study consist of active atmosphere, ocean, sea ice, and land components. This dataset includes the output from the atmospheric component (CAM4) and the oceanic component (MOM6) on Aqua and Ridge. The CAM4 data includes monthly surface temperature, precipitation, and surface pressure, and the 100-year climatology of all default output variables. The MOM6 data includes the 100-year climatology of the variables used in this paper.

## Description of the data and file structure

This dataset includes model output and case directories of CESM coupled Aqua and Ridge simulations. The coupled models consist of 1-degree CAM4 and CLM5 plus 2/3-degree MOM6 and CICE5. Both Aqua and Ridge have been integrated for 1100 years. Climatological diagnostics are based on the last 100 years (years 1001–1100). The CESM version used in this simulation is cesm2_3_beta06.

热带气旋的生成与发展在很大程度上取决于大尺度环境场的适宜性。本研究利用两个理想耦合气候模式，揭示了纬向非对称性对热带气旋生成规模与分布的影响。我们首先考察了纬向对称的配置模式"Aqua"，该模式下的行星除两极冰盖外均被海洋覆盖。随后在"Ridge"模式中，我们通过在两极冰盖之间引入一条单网格宽度的理想化大陆带，打破了原有的纬向对称性。

本研究采用的耦合地球系统模式（CESM）配置包含活跃的大气、海洋、海冰与陆面分量模块。本数据集包含Aqua与Ridge两个配置下的大气分量模式（CAM4）与海洋分量模式（MOM6）的输出结果。其中CAM4数据包含月平均地表温度、降水、地表气压，以及所有默认输出变量的百年气候态数据；MOM6数据则包含本研究使用变量的百年气候态数据。[内容截断]

## 数据与文件结构说明

本数据集包含CESM耦合模式下Aqua与Ridge模拟的模型输出文件与案例目录。耦合模式采用1度分辨率的CAM4与陆面模式（CLM5），搭配2/3度分辨率的MOM6与海冰模式（CICE5）。Aqua与Ridge两个模拟均已积分1100年，气候态诊断分析基于最后100年（第1001至1100年）的数据。本模拟使用的CESM版本为cesm2_3_beta06。
