【摘要】 大风是辽宁地区一种常见的天气现象,常常给工、农业生产造成严重的经济损失,而另一方面风能的利用又给国民经济的发展提供了可再生的绿色能源。因此对大风和风能资源进行研究和分析,将有利于趋利弊害,是人类向征服自然、改造自然迈进的重要一步。本文一方面针对辽宁省不同地区大风天气气候特点,对其进行时空分析,揭示近30年来辽宁省大风天气发生发展的气候学变化规律,并做出辽宁省大风风速和主要风向的区划,对关键大风时段进行了大气环流形势分析,力求更好地掌握大风的多发地区和主要时段,指导大风天气预报,趋利弊害,把风灾损失降到最小程度。另一方面本文计算了辽宁省表征风能资源储量的各项参数,并对风电场选址的测风资料进行了个例分析,进行了辽宁省的风能资源储量区划和全省高分辨率风能资源分布的数值模拟,较详尽说明辽宁风能资源状况,为大规模开发利用风能资源提供科学依据。

【Abstract】 Gale is a common weather phenomenon in Liaoning, which always results in severe economic loss in industry and agriculture. However, the wind energy, as regenerable green energy, can also provide new resource for the development of the national economy. Therefore, the survey of the gale occurrence and the related wind energy resource, which is helpful to exploit the advantage and prevent the disadvantage, is the first step toward the goal that human being conquers and remakes nature. In this study, by the spatial and temporal analysis of the synoptic and climatic characteristics of gale in different parts of Liaoning province, the climatological variation of gale weather occurrence and development within near 30-year in Liaoning is disclosed. Based on this investigation, the velocity and the prevailing direction of gale are compartmentalized in Liaoning; the general circulation patterns are also analyzed in the key gale period in order to better localize the area and the main period of the frequent occurrence of gale, guide the forecast of the gale weather, exploit the advantage and prevent the disadvantage, and minimize the loss related to the wind disaster. Meanwhile, the parameters, which represent the capacity of the wind energy resource, are also calculated in this study. The tower wind observations in the proposed wind power plants are studied according to the case data. Calculate wind energy capacity numerical simulation. The compartment of the wind energy capacity in Liaoning is detailed introduced in order to understand the situation of the wind energy completely and make scientific foundation for the large-scope exploitation of the wind energy resource.
