ABSTRACT

An attempt is made in this research to examine the distribution of rainfall in Nigeria within the framework of the dominant influence of the Intertropical Discontinuity (ITD) which is a boundary separating the dry northern air from the moist southern air. The aim of the study is to know the influence of the ITD in the distribution of rainfall in Nigeria. The Student ‘t’ test was employed to test the hypothesis as well as the significant difference, while the correlation analysis was used to explain the strength of the relationship between the two variables (rainfall and ITD position). The result shows that there is a significant difference between the distribution of rainfall in Nigeria and the position of the ITD and there was a weak relationship between the two variables. There should be easy accessibility to data which will aid in the proper and productive research on subsequent areas of study; decision-makers should also key into this research, falling back to it as a guide or reference and with the support of the government, more researches in climate-related studies should be encouraged.
