Observations and numerical simulations of a valley‐exit wind in the Alpine Bolzano basin
Quarterly Journal of the Royal Meteorological Society, EarlyView.The evolution and spreading of the nocturnal valley‐exit wind flowing from the Isarco Valley into the Bolzano basin, in the Italian Alps, are found to be influenced by the basin temperature stratification. Measurements and high‐resolution simulations show that a cold‐air pool favors an upward trajectory of the flow at the exit of the valley.
