Trend Change Analysis of Surface Air Temperature over Assam, India
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 9
Abstract
Temperature is one of the indicative factors of climate change which is a very important issues discussed in the recent two decades. The present research aimed at studying temporal and seasonal variation in surface air temperature over Dhubri, Guwahati, Silchar, Tezpur and Dibrugarh in Assam, India during the period 1979-2013. Trend in annual and seasonal temperature series is analyzed using Mann Kendall test. The analysis showed that the temperature trend, both annual and seasonal has increasing tendency during the period 1979-2013. The study showed that the annual mean temperature ranges between 24.14⁰c-25.67⁰c over all studied locations. Significantly high value of temperature is found for the month of August compared to all other months. A positive trend was studied for all four locations except Dhubri. It means that Assam is experiencing a rise in surface air temperature too. It might be due to the population growth, deforestation, industrialization etc. It is going to addition of global warming. Thus the research developed in this study could assist the prediction of the temperature over the studied locations.
