Osservazioni di microvariazioni di raggi cosmici in corrispondenza al passaggio di perturbazioni frontali

Abstract

Peculiar small variations of the total component of<br />cosmic rays have been observed during atmospheric cold front perturbations.<br />These variations have an amplitude of the order of 1% and a dur<br />a t i o n of a few quarters of an hour. The possible causes are discussed<br />and it is concluded on t h e possibility of an effect of t e m p e r a t u r e or of atmospheric electricity.
