CESM2 and E3SM variables used for diagnosing westerly wind events

This data set contains variables needed to identify and evaluate westerly wind events (WWEs) in a simulation using the Community Earth System Model version 2 (CESM2) and a simulation using the Energy Exascale Earth System Model (E3SM). The CESM2 simulation was a historical run from 1980–1999 that was restarted from the CMIP6 historical simulation. The E3SM was a 400-year pre-industrial simulation from which we analyzed the last 39 years. Only those last 39 years are included in the E3SM files. For both the CESM2 and E3SM simulations, meridionally-averaged zonal wind stress from 2.5°S – 2.5°N filtered from 5–90 days was used to identify westerly wind events in the Pacific Ocean (120°E – 280°E). Events were defined as patches of zonal wind stress in the time-longitude plane with zonal wind stress values of 0.04 Nm-2 or larger that lasted at least 5 days and were at least 10° longitude long. Meridional wind stress was also used along with the zonal wind stress to make spatiotemporal compo...本数据集包含用于识别和评估两组数值模拟中西风事件（Westerly Wind Events, WWEs）所需的变量，这两组模拟分别采用第二代社区地球系统模型（Community Earth System Model version 2, CESM2）与能源极端尺度地球系统模型（Energy Exascale Earth System Model, E3SM）。其中CESM2模拟为1980–1999年的历史运行试验，其初始条件重启自第六次耦合模式比较计划（CMIP6）的历史模拟序列。E3SM模拟为时长400年的工业前试验，本研究仅分析其最后39年的数据，因此E3SM数据文件仅包含该时段的模拟结果。针对两组模拟，研究均采用了经5–90天带通滤波、在2.5°S至2.5°N纬度带内经向平均得到的纬向风应力数据，用于识别太平洋区域（120°E–280°E）内的西风事件。事件判定标准为：在时间-经度平面上，纬向风应力数值不低于0.04 N·m⁻²、持续时长至少5天且经度跨度不小于10°的纬向风应力斑块。此外，研究同时结合经向风应力与纬向风应力，以开展时空合成...
