Résumé partiel
The present investigation entitled “Influence of Climatic Parameter Variability on Evapotranspiration in Semi arid Region” was undertaken to perform the trend analysis of climatic parameters and derived parameter such as reference evapotranspiration. The Climatic data of 42 year (1971-2012) for Parbhani station (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, sunshine hour, wind speed, rainfall and evapotranspiration was divided into four decades. 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 was calculated by statistical measures as I percent deviation, Mean, Standard deviation and Coefficient of Variation. The results obtained for Maximum temperature series indicated increase in temperature from last forty year by 0.1 to 0.25% since 1971. The maximum increase of 0.6% was in the year 2012, The MK trend test showed highest heat in the October whereas the annual average temperature did not show any trend. The relative humidity shows the rising trend of 2 to 6 % especially during monsoon and winter since last ten year (2001). Annual average maximum relative humidity in D3 (1991-2000) and D4 (2001-2012) decade was increased. The average annual and seasonal wind speed decreased during last two decades D3 and D4. The Mann Kendall test indicated decrease in average annual and seasonal wind speed with highest significance level since last three decades D2 (1981-1990), D3 (1991-2000) and D4 (2001-2012). The average annual sunshine hour was increased in D2, D3 and D4 decades.
