| 根据广东、浙江沿海2个100m气象铁塔上10、25、50、75、160m五层各1年的逐时温度、风速梯度资料,研究理查逊数(Ri)在沿海近地层大气稳定度分类中的应用。结果表明:目前常用的理查逊数稳定度分类标准不适用于沿海地区,根据沿海地区的实际资料,本文推荐了一种适用于沿海地区的Ri数稳定度分类标准。 |

| Abstract: |
| Richardson number's stability classifying schemes of the surface layer over the coastal region are analyzed by using the data obtained from two 100m towers located on the coastal area of Guangdong and Zhejiang provinces. Based on the wind speed, temperature, and wind direction data obtained at 10, 25, 50, 75, 100m,it is found that the limits of stability classes of the routine Richardson number classifying schemes were not available for the coastal region. A new Richardson number classifying schemes limit of the coastal region is proposed. |
