Description: ULF waves in Pc4 and Pc5 bands are often correspond to Alfvén waves that are eigenoscillations of terrestrial magnetic field lines. These waves can be generated from both external and internal sources. The former are thought to be a source of toroidal waves, while the latter ones are related to poloidal wave generation. Compressional waves are observed at the same frequency band as well. In the present study we used 46 months (March 2017–December 2020) of Arase satellite data to analyze spatial distribution of Pc4-5 waves. During this time interval Arase made three observations of all MLTs. A high inclination of Arase orbit was used to show meridional distribution in addition to equatorial one. We discuss the obtained distributions for poloidal, toroidal and compressional waves taking into account case studies. A clear difference between distributions of all 3 polarizations suggests a prominent separation in polarization analysis, but we found just a single cluster on 〈b||〉/〈ba〉 vs. 〈b||〉/〈br〉 diagram. This fact shows that polarization transformation from poloidal to toroidal wave and vice versa, and coupling of Alfvén and compressional waves play an important role in the magnetosphere. We used SYM-H index to characterize global magnetic disturbances and SME index to pay attention to substorm activity. Poloidal and toroidal wave distributions step back from the Earth during quiet geomagnetic conditions. Plasmapause location may be responsible for this behavior. We analyzed solar wind parameters and interplanetary magnetic field vector during wave observations as well.
