Global‐scale sea‐surface temperature anomalies and rainfall characteristics in northern Nigeria
Abstract Composite rainfall data over the 35‐year period 1951–1985 from seven Nigerian synoptic stations, all around latitude 12°N, have been used to examine the correlation, or otherwise, between global‐scale sea‐surface temperature (SST) anomalies and rainfall characteristics on the fringe of the...
