Study on Correlation between Southwest and Northeast Monsoon Rainfall over Tamil Nadu
Journal Title: Universal Journal of Environmental Research and Technology - Year 2011, Vol 1, Issue 4
Abstract
In the present study 110 years (1900-2010) data is used for studying correlative effects between southwest (June-September) and northeast monsoon (October –December) rainfall over Tamil Nadu. For the period of different solar cycles, we compute the correlation coefficients using Spearman Rank technique. A correlation analysis between the two rainfall series revealed that the southwest monsoon rainfall is negatively correlated with that of the northeast monsoon rainfall. That is, an excess or deficit of southwest monsoon rainfall over this region is generally followed by an opposite tendency in the northeast monsoon rainfall. It also reveals that the rainfall in the two monsoons is not independent of each other. The negative rainfall relationship can be a useful tool in foreshadowing the northeast monsoon rainfall over Tamil Nadu, which is of considerable economic importance for this region.
