摘要：

One of the mechanisms of Alfven turbulence generation in the foreshock region is investigated by the example of the Earth bow shock. The effect of the temperature of high-velocity beams on characteristics of generated disturbances is examined. It is shown that the beam temperature has a significant impact on transverse scales of disturbances. The higher the temperature, the greater the limitations on transverse wavelengths. The development of instability in the propagation of reflected, intermediate, and diffusion proton beams in the foreshock region of the Earth bow shock is considered. Perturbation motion dynamics in foreshock region is analyzed.
