Climate change impact assessment on rainwater in Jordan

Abstract

This article aims to investigate the possible trend in precipitation and temperature in the agricultural areas in Jordan. Six meteorological stations locate in the agricultural areas in Jordan were chosen to investigate the variation in precipitation, maximum and minimum temperature. In order to achieve accurate result, quality control was conducted for each station. Also the homogeneity test was conducted using Standard Normal Homogeneity Test, Pettitt and Von Neumann ratio tests. All stations passed the quality and homogeneity tests. Data were analyzed using the recommended software RClimDex to determine 27 climate indices. The obtained results indicated significant trend in many indices. The most significant trend was found for cool days, warm days, warm nights, cool nights, summer days, diurnal temperature range, and the tropical night indicators. Further studies to quantify the climate change in Jordan were recommended. (C) 2017 The Authors. Published by IASE.
