Description
This study appraises anticipated vicissitudes to surface wind characteristics from
1980-2018 in Ikogosi South-Western Nigeria. Changes in wind speeds at regional and global
levels are signals of global warming. A concern about climate change has been a major driving
force for the speedy expansion experienced in wind energy projects. Yearly investigation of
wind speed disguises seasonal variation in predictive planning. At times, these changes
fluctuate across seasons in some zones. The Inter-governmental Panel on Climate Change
(IPCC) gave a proponent for long-term changes in the large-scale atmospheric circulation. In
effect, observed changes such as poleward shifts and reinforcement of westerly winds will
likely be promoted. Projected changes to annual wind speed display altitudinal variability
compared to seasonal and annual mean wind speed. An evaluation of wind changes at specific
locations is therefore necessary for site-specific application. This paper presents experience at
Ikogosi warm spring site with varying return periods, analysedfor identificationof the
behaviour of its wind using several statisticsprobability distribution. Average wind speed of 2.2
m/s in Ikogosi certainly portends a future for hydro-electricity alternative in Nigeria.
