Dependence of the north-south component of IMF on the solar wind acceleration
- 23 Downloads
The monthly probability of occurrence of southward (B z − ) component of IMF estimated independent of the sector polarity observed near earth is found to change with the magnitude of solar wind velocity. The above analysis is done for each month during two years around sunspot minima and maxima in cycle 21. The results will be interpreted in terms of association of southwardB z events with solar wind flows of distinct solar origin such as low and high speed solar wind.
