On mean state of the atmosphere at the end of rainy season in Southwest Nigeria during

Keywords: Incursion, Rainy, Squall lines.


For a long time upper air data Nigeria had been fragmentary. Poor operational upper air network had therefore been responsible for the poor products users get from the forecast office.

This paper describes the wind information obtained during a specifically designed meteorological experiment tagged “Mesoscale Experiment I” to monitor the pattern of wind flow at low-levels during the occurrence of squall lines systems at the end of rainy season in three locations in Southwest Nigeria from 28th Sept/9th Oct 1991. Analysis of both the zonal and meridional wind components showed that the southerlies were favourable for bad weather. The winds were found to be generally weak southerlies at the end of the rainy season.
