Abstract

Monitoring of rainfall has become necessary, because of the adverse effects of rainfall variability (e.g. floods, drought, poor harvests, etc.) on agriculture as well as economy. This study is geared towards a better understanding of rainfall variability in Maiduguri, an agrarian community, and sea-surface temperature using Mann-Kendall statistical analyses of data for a period of thirty-four years from Nigeria Meteorological Agency (NIMET) and National Oceanic and Atmospheric Administration (NOAA) website. Results showed that generally, rainfall in Maiduguri is on the decline and very variable. The sea surface temperature showed an increasing monotonic trend within the period studied.

Key words: Rainfall, sea-surface temperature, trend, variability.
