Diurnal Valley Winds in a Deep Alpine Valley: Observations
Autor: Fabienne Schmid, Juerg Schmidli, Maxime Hervo, Alexander Haefele
Publikováno v: Atmosphere, Vol 11, Iss 1, p 54 (2020)
Diurnal valley winds frequently form over complex topography, particularly under fair weather conditions, and have a significant impact on the local weather and climate. Since diurnal valley winds result from complex and multi-scale interactions, the
