摘要：

We report experimental observations and computer modeling results of large-scale density and temperature modifications (several km extent, delta-T(e)/T(e)O approximately 3, \delta-n(e)\/n(e)O approximately 25%) created in a low-density, mid-latitude, night-time ionosphere by nonlinear refraction of an hf beam launched from a ground-based antenna. The process consists of the reorientation of the reflection surface parallel to the geomagnetic field lines and results in intense heating.
