研究了2010年1月15日环食对近地面层风和温度光谱行为的影响。在食峰时，风的谱功率和湍流动能耗散率减小了一个数量级，而温度则减小了一个数量级以上。风分量的谱特征在峰值阶段被注意到，并首次，地面风速和风向与日食的风分量的谱特征的影响进行了研究。(C)2013爱思唯尔有限公司保留所有权利。
The influence of annular solar eclipse of 15 January 2010 on the spectral behaviour of surface layer winds and temperature has been investigated. At the peak of the eclipse, the magnitudes of spectral power of wind and the rate of dissipation of turbulent kinetic energy decreased by an order whereas, the temperature decreased by more than one order. A distinct spectral characteristic of wind components is noticed during the peak phase and for the first time, influence of surface wind speed and wind direction associated with the eclipse on the spectral characteristics of wind components has been investigated.
