Alpine planetary boundary layer

Due to its high spatial and temporal variability, the planetary boundary layer (PBL) behavior over a mountainous terrain is more complex than over a flat terrain. The fast changing local wind system directly linked to topography and the variable land cover that goes from snow to vegetation have a significant impact on the growth of the PBL and make it much harder to predict.
Understanding the processes inducing changes in the mountain PBL have critical applications for predicting air pollution transport, fire weather and local intense thunderstorm events. While some processes, such as mountain waves, have been well studied in the mountain PBL due to their importance for aviation, most of the behaviors of the alpine PBL are relatively unknown.〔(''Investigation of the Planetary Boundary Layer in the Swiss Alps Using Remote Sensing and In Situ Measurements'' )〕

The PBL in complex terrain is shaped by three local (non synoptic) wind systems occurring at different scales, which are closely related to the structure of the topography. The height of the PBL can be observed using radio soundings, which measure temperature and humidity gradients or LIDAR, which measures the backscatters of the aerosols.
