Data from the &esund experiment are used to investigate the structure of the stably stratified internal boundary layer (SIBL) which develops when warm air is advected from a heated land surface over a cooler sea. The present study is based on a theory developed by Stull (1983a, b, c). He proposed th

โฆ Synopsis
Airplane measurements in the stable boundary layer during the SESAME-1979 experiment (southcentral Oklahoma, U.S.A.) are examined in terms of the local similarity theory. The obtained results are compared with data from the Minnesota (1973) experiment and with data collected previously on towers in Cabauw (Netherlands) and Boulder (Colorado, U.S.A.). The comparison indicates that the SESAME data are strongly influenced by the terrain features of the experimental site.

A stable boundary layer is investigated in terms of local similarity theory. A study is based on a set of seven runs from the BAO tower (Colorado, U.S.A.). It is shown that a theoretical prediction of constant-with-height similarity functions applies only to ensemble-averaged quantities. Scatter of
A one-dimensional model based on the equations of mean motion and turbulent kinetic energy (TKE) with a mixing-length closure scheme has been developed to simulate the turbulence structure of the evolving stably stratified nocturnal boundary layer (NBL). The model also includes a predictive equation
