THE RELATIONSHIP BETWEEN ATMOSPHERIC PRESSURE AND WIND SPEED AT THE SOUTHERN FOOT OF THE ALPS. ITALY
A regular decrease of the atmospheric pressure has been observed during the valley breeze, which blows on sunny afternoons in the Lombardy hills at the southern foot of the Alps. A second diurnal decrease of the atmospheric pressure has been observed during the mountain breeze at night. However, the specular variation of these two elements is not due to the cause - effect connection, because two daily minima and two daily maxima of atmospheric pressure are present also on cloudy days, when no breeze exists. The only common effect is the heating of the air in the Ispra basin during the sunny afternoons, when the sun causes both the valley breeze and further decrease of the atmospheric pressure, which is deeper than on cloudy days.
