Abstract

Introduction: Jamaica is known as the land of wood and water, but some areas of Jamaica experience water issues such as extended dry spells and low-flowing rivers. It is common to see houses with rainwater gutters in Manchester and Clarendon that lead to ground tanks.


Objectives: 1) to assess rainfall in Manchester and Clarendon, 2) to compare the rainfall in the parishes of Manchester and Clarendon, and 3) to evaluate any correlation between rainfall in Manchester and Clarendon.


Methods: The current study employs time series data from 2001 to 2021 as it relates to the level of rainfall in the parishes of Manchester and Jamaica. The data were obtained from the Office of Jamaica Meteorological Service (JMS). The data were stored, retrieved and analyzed using the Statistical Packages for the Social Sciences (SPSS), for Windows, Version 27.0, and Microsoft Excel. Descriptive statistics, changes in percentages, and graphs to examine the univariate variable of the ever-changing levels of rainfall in both Manchester and Clarendon.


Findings: Manchester gets more rainfall (147.9±32.26mm) than Clarendon does for the studied period (101.1±42.26mm) - t=11.583, P < 0.001. Manchester had heavier levels of rainfall, ranging from 99mm to 219mm, throughout the years as compared to Clarendon, whose levels ranged from 38mm to 168mm, in no particular order. There is a very strong statistical correlation between rainfall in Manchester and rainfall in Clarendon (rxy=0.913, P< 0.001; Table 3).


Conclusion: Rainfall is affected by many factors; water's unique chemistry and properties allow it to act in the way it does. Water will always try to go to a region of low concentration. Access to this precious commodity is vital to human survival; we depend mainly on rainfall to supply our water needs.
