| Abstract: | The Boundary Layer Transformation Model(BLTM) is tested against data on the observed depth ofthe thermal internal boundary layer (TIBL).The model is based on a semi-empiricaltheory of the atmospheric boundary layer and takes into account theinfluence of the sea-land temperaturedifference and other meteorological conditionsduring the TIBL development. The measurementswere carried out during ATHens InternalBoundary Layer EXperiment (ATHIBLEX) in 1989and 1990. It is found that the BLTM results arein good qualitative agreement with theobserved TIBL depths. The reason for thediscrepancies between the observed andcomputed depths is explained by the differentdefinitions of the TIBL adopted. |
