Abstract

The climatological factors like rainfall, temperature, humidity, wind patterns, atmospheric pressure, etc, have a profound impact on the environment. The changes in the climatological factors have interconnected effects on ecosystems, water resources, coastal areas, agriculture, forestry, human health and bio-diversity. The objective of the present work is to study the trend patterns in climatological and meteorological factors along with the effect of those variables on the crop yield. The coastal district, Thiruvarur of Tamil Nadu was selected for the study to anlayse the climatological factors and their effect on the crop yield. In addition, Mettur dam outflow was analysed with the mann-kendall and innovative trend analysis. The findings of the study revealed the trend patterns in the study area. The monthly mann-kendall trend statistics shown that there is a negative trend in February month and positive trend in the rest of the months. While, the innovative trend analysis inferred that negative trend is realised in the months of February, April, June and positive trend in the remaining months. The trend analysis of the climatological factors is crucial for addressing the impacts, adaption to climate change and protecting the environment for the future.
