Abstract:
The present study examined the variability and trend of these climate variables for Dapoli (Maharashtra) over 37 years, from 1985 to 2021. While non-parametric methods like the Mann-Kendall and Sen's slope estimator test have been used to study trend analysis, statistical parameters have been used to analyse the variability of these climatic variables. The average annual minimum and maximum value of rainfall, maximum temperature, minimum temperature, maximum relative humidity, minimum relative humidity, wind speed, sunshine hours, and pan-evaporation were found as 2330.7mm and 5421.4mm, 30.4 ℃ to 31.8 ℃, 17 ℃ to 20.2 ℃, 88.8% to 95.1%, 61.3% to75.4%, 3.8 km/hr to 5.4 km/hr, 6 hrs/day to 7.7hrs/day, and 1196.4 mm to 1780.8 mm, respectively. Annual trend of T_min, T_max, RH_min, and RH_max significantly increasing at 99.9%, 99.9%, 99.9%, and 95% levels of significance with a magnitude of 0.05 ℃/year, 0.03 ℃/year, 0.19%/year, and 0.07%/year, respectively. Wind speed and sunshine hours showed a decreasing trend at 95% and 99.9% levels of significance with the magnitude of -0.01 km/hr and -0.03 hr/day, respectively. There was no significant trend found for rainfall and pan-evaporation.
