风能是地球表面大量空气流动所产生的动能。由于地面各处受太阳辐照后气温变化不同和空气中水蒸气的含量不同，因而引起各地气压的差异，在水平方向高压空气向低压地区流动，即形成风。风能资源决定于风能密度和可利用的风能年累积小时数。本数据集主要服务于风电开发的勘探和初步风能资源评估阶段，即还未在现场建立气象观测站的阶段。它也是帮助政府充分了解各地风能资源潜力的有力工具。", "ds_source": "

Wind energy is the kinetic energy generated by a large amount of air flow on the Earth's surface. Due to the different temperature changes and water vapor content in the air after being irradiated by the sun at various locations on the ground, differences in air pressure are caused, and high-pressure air flows horizontally towards low-pressure areas, forming wind. Wind energy resources are determined by wind energy density and the annual cumulative hours of available wind energy. This dataset mainly serves the exploration and preliminary wind energy resource assessment stage of wind power development, which is the stage where meteorological observation stations have not yet been established on site. It is also a powerful tool to help the government fully understand the potential of wind energy resources in various regions.
