Along a loop, 8650 m long and traversing a hilly landscape, the air temperature was measured at four levels (0.2, 1.0, 2.0 and 3.0 m a g). ... Sudden rises in air temperature at 2.0 m occurred at a number of elevated locations along the loop, at a maximum rate of 3.5°C/hour, indicative of the influence of dynamic turbulence.

CONT

In spring, dust storms take place in deserts and dry loess plateau ... These vast areas are located in the lee of the massive East Asian Mountains where a convergent airflow and a lee cyclone take place on a synoptic scale. ... In particular, a convergent flow in a lee cyclonic system enhances an upward motion, and dust produced by mechanical and dynamic turbulence can be transported to the midtroposphere ...

CONT

Dynamic turbulence in the atmospheric planetary boundary layer.

La turbulence dynamique provient du frottement de l'air en mouvement contre un sol présentant une certaine rugosité : accidents du relief, végétation, constructions...

CONT

Afin de pouvoir quantifier les échanges d'ozone et de cerner l'impact de cette molécule sur le fonctionnement des couverts forestiers et agricoles, nous avons cherché à paramétrer sa vitesse de «dépôt» (i.e. absorption par des surfaces, circulation dans des pores et autres voies de transfert [...]). [...] le dépôt nocturne en conditions sèches est contrôlé par la turbulence dynamique (vitesse de frottement); pour des conditions dynamiques données, le dépôt augmente sensiblement avec l'humidité relative de l'air; si le dépôt stomatique est dominant en conditions diurnes [...]
