IMF (Input from Magnetic Field) Bz and Solar Wind Speed Dependence for Precipitating Ion Hemispheric Energy Flux

摘要

A new statistical study of the total power input to high latitude regions from precipitating ions, making primary data sorts by the IMF Bz and solar wind speed, shows that a) the minimum power input occurs for low, positive values of Bz and low values of Vsw, b) power input increases proportionately more with increasing Vsw than with increasing Bz negative.
