Dependence of muon flux at the Earth's surface on atmospheric conditions (pressure, temperature, humi humidi- ity, etc.) opens a possibility to study these parameters by detection of muon flux variations. For that, special dete ty, detector tors– muon hodoscopes –which can register muons from any direction of the upper hemisphere with a good angular resol resolu- ution (about 1 degree) are required. Such type detector URAGAN is now under operation in National R tion Research Nu search Nuc- clear University MEPhI. In this pape lear paper, results of observations of angular r, angular-temporal variations of muon flux are co consi- idered. Obtained sequence of 2D angular matrices (f.e., in zenith projection angles) allows one to search for spatial dered. spatial- angular changes in muon flux and trace the development and direction of moving of atmospheric disturbances. E Ex- xamples of various atmospheric processes are analy amples analyzed and possibilities of their early revealing are discussed.
