Statistical data summarization techniques, curve fitting methods and statistical tests, both parametric and non-parametric, have been applied to form a comprehensive idea about pre-monsoon weather over South Bengal situated in the northeastern part of the Indian sub-continent. The work is based on surface data recorded at 15 major observatories during the period 1969-2000, spread across the western plateau and highlands, Rarh and Gangetic region of South Bengal. The homogeneity of pre-monsoon rainfall and its variability over different stations has been studied using Bartlett`s and Kruskal Wallis tests. For stations with complete weather information for at least 30 consecutive years, time series analysis has been carried out on rainfall data for a climatological overview of long-term behaviour, seasonal and cyclical fluctuations of pre-monsoon rainfall in those areas. This paper, apart from being a regional study, highlights the use of certain parametric and non-parametric tests, not so widely used in the context of climatology.
