Abstract: One of Alfven turbulence generation mechanism is investigated in foreshock region by the example of Earth bow shock. The fast speed beam temperature influence on generated perturbation characteristics was studied. It is shown, that beam temperature exerts essential influence on transverse scales of disturbances. The higher temperature the stronger limitations impose on transversal length of waves. The development of instability of reflected, intermediate and diffuse protons beams, which propagates in foreshock region of Earth bow shock, is considered. Perturbations motion dynamics is analyzed in the foreshock region. |
| Keywords: Alfven turbulence, Earth bow shock, protons fast speed beams |
