虽然边界层过程在气候、天气和空气质量方面很重要，但边界层气候学很少受到重视，部分原因是缺乏观测数据集。我们分析边界层气候学在欧洲和美国大陆使用的边界层高度的基础上散装理查森数的措施。1981-2005年期间的季节和日变化估计从无线电探空观测，同化观测的再分析，和两个当代气候模式，不。垂直剖面数据的局限性导致高度不确定性，对于浅层边界层，高度不确定性可能超过50%（
Although boundary layer processes are important in climate, weather and air quality, boundary layer climatology has received little attention, partly for lack of observational data sets. We analyze boundary layer climatology over Europe and the continental U.S. using a measure of boundary layer height based on the bulk Richardson number. Seasonal and diurnal variations during 1981-2005 are estimated from radiosonde observations, a reanalysis that assimilates observations, and two contemporary climate models that do not. Data limitations in vertical profiles introduce height uncertainties that can exceed 50% for shallow boundary layers (
