Abstract

The simulated nocturnal boundary layer height, h, from several widely used diagnostic relations as well as from one prognostic relation, is compared with direct estimation of h, from radiosonde profiles available at 24h Z. The required input data are no more than surface wind speed, air temperature and total cloud cover. Of these, best performance is found using the relationship of Nieuwstadt [1]. It should also be mentioned that the comparison of estimations of h, against measurements improved when the observed height was determined at the maximum wind. 1. Introduction Simplified models of the atmospheric boundary layer are necessary in many applications, including num
