AN ASSESSMENT OF METEOROLOGICAL CONDITIONS IN AKURE, ONDO STATE, NIGERIA

Abstract

The aim of the study was to assess the meteorological conditions of Akure, Ondo State, Nigeria. The data was obtained at the observatory unit of the Federal University of Technology, Akure. The observation was made for a period of six months. The results were subjected to statistical analysis. The avearge results of the rainfall ranged from 0 (no rainfall) to 11.60mm, the average speed (m/s) ranged as follows: 0.26, 0.28, 1.09, 1.41, 0.26 and 0.41 (July, August, September, October, November and December respectively), the temperature recorded in the months were high mostly > 25^oC and the relative humidity in all the months ranged from 51.78 to 91.24% with low standard deviations. Statistically, most of the parameters were negatively correlated. From the results obtained for rainfall, temperature and relative humidity, it could be deduced that there was scanty rainfall. This observations could have serious effects on farm produce and human health.
