The Vector dynamics of Ikogosi Wind Speed/direction relative to Climate Change

Abstract

Abstract 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.
