Abstract
Jovian hectometric radiation(HOM) emitted from the polar region of the Jovian magnetsphere reflects the information on the electro-magnetic environment of the source region. Using the Ulysses URAP and SWOOPS data, the occurrence characteristics of HOM and its relation to the solar wind were investigated. As a result, we found that HOM can be classified into two components; (1) Solar wind HOM(sw-HOM), whose amplitudes are related to the solar wind dynamic pressure, and (2) non Solar wind HOM(nsw-HOM), which is independent to the solar wind parameters and is observed with large amplitudes. These two components have different system III occurrence characteristics. Considering the relationship with Jovian aurora, L values of each HOM source are inferred to be L>30, L≃12, respectively.
