摘要：
A study of the geomagnetic field response to a series of continuous solar wind pressure variations has been performed at a low-latitude station during interplanetary events characterized by stable northward magnetic field conditions. The geomagnetic field H component responds well to the solar wind pressure changes on a timescale of few minutes. The amplitude of the geomagnetic field response is found to depend on local rime, showing greater values around local noon and midnight.
