On cosmic ray intensity variations with a period of 160 min

By the data of high-mountain neutron supermonitor of Alma-Ata station frequency spectrum of cosmic ray intensity short-period variations is investigated. It is shown that in quiet intervals of 1974-1985 period a peak with a period of 160 min exceeding 95% confidence interval appears in spectra. For a number of spectra the following peculiarity is traced: in frequency spectra of pressure and data not corrected for the pressure this peak is not observed, while in data corrected for the pressure it is evident
