This script is to explain how anticyclonic convergence at the 200 hPa level with a corresponding cyclonic convergence at the 925 hPa level produced rainfall over Southern Ghana, specifically over the Brong Ahafo Region. Continental winds prevailed over the Brong Ahafo Region on that day which, under normal or usual circumstances would not have yielded any rainfall due to the dryness but the convergence was so deep and the atmosphere became absolutely unstable. Usually anticyclonic circulations are associated with divergence but the unusual occurred on that day over Ghana, it happens ?once in a blue moon?.
