Figure 4.2 Annual rainfall fluctuations and trend at Aburi (1965-1994)
Apart from Suhum, all the other stations showed a negative trend line equation,
which is indicative of a general decline in rainfall. Since 1980, most of the rainfall
stations in Ghana have exhibited this declining pattern. If data were available for
Suhum, they probably would have exhibited similar characteristics.
