The Ceylon Journal of Science is a peer-reviewed journal published quarterly by the University of Peradeniya, Sri Lanka in March, June, September and December. It is aimed at publishing high quality research articles on topics related to different disciplines in Science. The journal accepts original research articles, book reviews, reviews and mini-reviews, short communications, opinions, research notes, and commentaries and notes. The journal strictly adheres to publication ethics as emphasized by the Committee on Publication Ethics (COPE). The Journal has its own website.The Ceylon Journal of Science is indexed in Sri Lanka Journals Online (SLJOL), Directory of Open Access Journals (DOAJ), Google Scholar and Zoological Records.

Highlights
Precipitation is a main component in the hydrologic cycle
Comparison of monthly average rainfall for rain gauge stations and wet zone divisions are shown in Figure 1 (a) and (b)
Analysis of monthly average rainfall for the considered consecutive 30 years revealed that Maliboda and Watawala, which are located in the hill country experienced the highest amount of rainfall during the Southwest monsoon compared to the other rain gauge stations considered in this research study (Figure 1a)
Summary
Precipitation is a main component in the hydrologic cycle. Sub-seasonal or seasonal variability of rainfall in areal and temporal scale is becoming a huge problem and many countries consider it as a consequence of climate change. Researchers have found that in Sri Lanka, variability of all seasonal rainfall has increased but annual rainfall remains closer to the average (Punyawardene, 2002). A limited number of research studies have been conducted related to seasonal rainfall variation in Sri Lanka. Investigations of the seasonal rainfall distribution considering agro climate zones and analyzing seasonal rainfall variation considering trend analysis will be useful in many socio-economic aspects. Agricultural land use in Sri Lanka roughly shows a division of the island into two major areas, according to the climatic division: wet zone and dry zone. They are referred to agro climate zones. Considering the geographic features, wet zone can be divided into three parts: Low Country, Mid Country and Up Country (Domroes, 1979)
