1）数据内容：全新世11.5ka以来轨道参数、温室气体和冰盖全强迫作用下欧亚地区200 hPa和850 hPa经向和纬向风速（反映高、低层西风和季风）；2）数据来源：利用地球系统模式CESM（水平分辨率约2°x2°）开展的全新世11.5ka以来瞬变模拟试验，包括地球轨道参数、大气温室气体浓度、冰盖全强迫作用，试验从全新世（11.5ka）连续积分至工业革命前期（1850年），模式输出的逐月纬向风速数据；加工方法：年平均；3）数据质量：模拟结果与已有间接代用记录定性一致；4）数据应用：用于古气候变化和动力学机制研究。

1) Data Content: Zonal and meridional wind speeds at 200 hPa and 850 hPa over the Eurasian region since 11.5 ka of the Holocene under full forcing of Earth's orbital parameters, atmospheric greenhouse gases and ice sheets; these variables reflect upper- and lower-level westerly winds and monsoon systems.
2) Data Source: A transient simulation experiment since 11.5 ka of the Holocene was conducted using the Community Earth System Model (CESM) with a horizontal resolution of approximately 2°×2°. The experiment incorporates full forcing of Earth's orbital parameters, atmospheric greenhouse gas concentrations and ice sheets, and integrates continuously from the onset of the Holocene (11.5 ka) to the pre-industrial period (1850 CE). The model outputs monthly zonal wind speed data, which are processed into annual mean values.
3) Data Quality: The simulation results are qualitatively consistent with existing indirect proxy records.
4) Data Application: This dataset is utilized for studies of paleoclimate change and their underlying dynamical mechanisms.
