Using ground-based data from the Coupling Energetics and Dynamics of Atmospheric Regions (CEDAR) database, and satellite data from a variety of sources (including the Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) and Dynamics Explorer satellites), a global empirical model of thermospheric winds during magnetic storm periods is developed. The model will elucidate the spatial, seasonal, solar activity, and geomagnetic activity dependencies of storm-induced perturbation winds. The product is to be integrated into the commonly used Horizontal Wind Model (HWM), for direct use by the entire community. This model will improve the specification and forecasting capabilities of current numerical models of the thermosphere and ionosphere by provision of a known time-boundary condition.

利用来自大气区耦合能量和动力学(CEDAR)数据库的地面数据和来自各种来源(包括热层电离层中间层能量和动力学(TIMED)和动力学探测器卫星)的卫星数据，建立了磁暴期间热层风的全球经验模式。该模式将阐明风暴引起的扰动风的空间、季节、太阳活动和地磁活动的依赖关系。该产品将集成到常用的水平风模型(HWM)中，供整个社区直接使用。该模式将通过提供已知的时间边界条件，改进目前热层和电离层数值模式的规格和预报能力。
