Résumé partiel
The present investigation entitled “Influence of Climatic Variability on Reference Evapotranspiration for Beed station of Marathwada Region” was undertaken to perform the trend analysis of climatic parameters and derived parameter such as reference evapotranspiration. The Climatic data of 31 years (1983-2013) for three stations of Beed (Maharashtra) was collected and trend analysis was performed by using Mann Kendall test which is non parametric test. The daily meteorological data of temperature, relative humidity, wind speed and evapotranspiration was divided into three decades. Total three decades such as D1 decade for 1983-1992 period, D2 for 1993-2002 and D3 for the period of 2003-2012 were formed and the data for the year 2013 was used for comparison. Temporal change and their trend for each decade was investigate by annual, seasonal and monthly scale. Reference evapotranspiration was estimated by Penman Monteith 56 method. To investigate the trend Mann Kendall Test Software is used at 95% probability level. The temporal changes in each climatic parameter were calculated by statistical measures as percent deviation, Mean, Standard Deviation and Coefficient of Variation. The results obtained for maximum temperature indicated the average maximum temperature was increased by 0.51, 1.18 and 1.53% in the decade D1, D2 and D3 respectively and decreased by 3.26% in the year 2013. The MK trend test showed increase in trend in the month of July, September, October, November and December of decade D2, whereas the no trend showed in decade D1 and decade D3. It also showed increasing trend in winter season of decade D2 for station 1. The annual average maximum temperature for station 2 and 3 were 31.63 and 32.10oC.
