MONTHLY TREND ANALYSIS AND VARIABILITY OF CLIMATIC VARIABLESTARAI REGION OF UTTARAKHAND

Haseen Ahmad

Abstract :

 This present study focuses on the climate change, trend and variability in the tarai region of Uttarakhand. The monthly data (January to December) of climatic parameters over a period of 33 years (1981−2013) has been processed, analyzed to detect out trend and variability. Detection of monthly trend and variability is an objective to achieve the goal and observed an increasing trend in maximum and minimum temperature, rain fall, relative humidity and a decreasing trend in rainy days and wind speed. The Statistical analysis indicates a mean increase in maximum temperature is 0.002288o C and minimum temperature a mean increase is 0.03277 o C. Rainfall mean increase about 2.0378 mm over the region; with slightly mean decrease in rainy days is 0.0126 day. The mean relative humidity 712 and 1412 indicates an increase is 0.0555% and 0.0909%. Wind speed indicates slightly mean decrease about 0.0308 km/hour. Pearson’s correlation coefficient was applied to measure degree of relationship between mean rainy days and mean rainfall, (January to December) and observed the significant positive correlation ‘r’ is 0.988.Climatic parameters of tarai region maximum, minimum temperature, rainfall, rainy days, relative humidity 712 , 1412 and wind speed observed fluctuations, variations,an increasing and decreasing trend.
