Description:
The variation of the solar wind parameters (speed, magnetic field intensity, and proton density) and geomagnetic disturbance with location within the interplanetary sector structure is well established. The Kelvin-Helmholtz instability of the magnetopause provides a mechanism for the initiation of worldwide geomagnetic disturbance. Since the Kelvin-Helmholtz mechanism depends on an integration of several of the solar wind parameters, it was considered of interest to see how it varies within the sector structure. Support is given to the idea that the integration of the solar wind parameters via Kelvin-Helmholtz instability is an important concept in understanding geomagnetic disturbance.
