To evaluate temporal characteristic potential evapotranspiration, at annual and seasonal time scales in Alraqa station during the period 1975-2005, the enman-Monteith equation was applied to calculate monthly potential evapotranspiration (ETP) using meteorological data which include meaning maximum and minimum temperatures, relative humidity, winds speed, and sunlight duration. Trends with Mann \u2013 the Kendall test and point change analysis were used to detect significant changes in annual and seasonal ETP. The results showed a significant decreasing tendency in annual\u00a0 ETP related to decreasing ETP in all seasons, especially in summer. Annual values of ETP were Shifted during two periods: 1984-1985 and 1990-1991. This\u00a0 decreasing trend in ETP resulted\u00a0 from westerly\u00a0 wind direction\u00a0\u00a0 especially in warm months,\u00a0 which promotes increasing relative humidity\u00a0 in this region, owing to the location of Al Asad lake near this region<\/span><\/p>\n<p><span style=\"font-family: 'Times New Roman', Times;\"><strong>Keywords:<\/strong> Potential evapotranspiration, Climate change, Penman, Monteith, Syria.<\/span><\/p>\n<p><span style=\"font-family: 'Times New Roman', Times;\">Full paper in Arabic: <a href=\"http:\/\/agri-research-journal.net\/SjarEn\/wp-content\/uploads\/93p20.pdf\">pdf<\/a><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hanan Abdo(1)*and Michael Skaf(1) (1) Department of forestry and environment, Faculty of Agriculture, Tishreen University, Lattakia, Syria.
