Abstract: Vipavska dolina je geomorfološko dokaj zaprta, kar po eni strani omogoča pojav močne burje, po drugi strani pa ob stabilnih meteoroloških razmererah ugodne pogoje za kopičenje aerosolov znotraj prizemne mejne plasti. Poznavanje dinamike višinske porazdelitve aerosolov s sočasno uporabo prizemnih meritev omogoča raziskave lokalnih emisij aerosolov, transporta aerosolov na daljše razdalje ter značilnih atmosferskih struktur, ki se pojavijo v različnih vremenskih pogojih. Pri meritvah smo uporabili metode daljinskega zaznavanja z lidarjem, ki omogočajo opazovanje časovnega in prostorskega spreminjanja koncentracij aerosolov, ter točkovne meritve, ki omogočajo njihovo prepoznavanje in določanje njihovih lastnosti. Ugotovili smo, da je mogoče lidarske meritve uporabiti za študij vrste atmosferskih procesov in struktur v zelo različnih vremenskih pogojih. Opazili smo manjše konvekcijske strukture znotraj prizemne mejne plasti in gravitacijske valove nad njo. Meritve vsebnosti in lastnosti aerosolov pri tleh kažejo, da se lahko ob stabilnih atmosferskih pogojih v primerih povečanja lokalnih emisij njihove koncentracije hitro povečajo. Dinamiko in strukturo razširjanja aerosolov znotraj Vipavske doline bomo v prihodnje podrobneje raziskali s sočasnim prostorskim pregledovanjem z metodami daljinskega zaznavanja.

Abstract: The Vipava valley in Slovenia is well known for the appearance of strong, gusty North-East Bora winds, which occur as a result of air flows over an adjacent orographic barrier. There are three revealing wind directions within the valley which were found to give rise to specific types of atmospheric structures. These structures were investigated using a Mie scattering lidar operating at 1064 nm, which provided high temporal and spatial resolution backscatter data on aerosols, which were used as tracers for atmospheric flows. Wind properties were monitored at the bottom of the valley and at the rim of the barrier using two ultrasonic anemometers. Twelve time periods between February and April 2015 were selected when lidar data was available. The periods were classified according to the wind speed and direction and investigated in terms of appearance of atmospheric structures. In two periods with strong or moderate Bora, periodic atmospheric structures in the lidar data were observed at heights above the mountain barrier and are believed to be Kelvin–Helmholtz waves, induced by wind shear. No temporal correlation was found between these structures and wind gusts at the ground level. The influence of the wind on the height of the planetary boundary layer was studied as well. In periods with low wind speeds, the vertical evolution of the planetary boundary layer was found to be governed by solar radiation and clouds. In periods with strong or moderate Bora wind, convection within the planetary boundary layer was found to be much weaker due to strong turbulence close to the ground, which inhibited mixing through the entire layer.
