Variations in cosmic rays are investigated on the basis of the Tien Shan neutron monitor data. The Earth’s electrical field during snowfall, rain, and thunderstorm activity is considered as a modulating factor. It is established that the effect of the electrical field on the monitor data becomes apparent at values exceeding 15–20 kV m −1 in the atmosphere of a thunderstorm. The response is as high as 1.5% for recorded particles with energies lower than 10 GeV.
