The mean temperature trend during the wet season is significant except during 2000-2005, while there is an insignificant trend for the wet season temperature in the eastern parts of the study area.

A change in spatial distribution over time in all parameters was observed where alternation occurred between dry and summer seasons, evidenced by a negative covariance with an r value of -0.4. The changes in temperature and precipitation contribute 25.86%, 30.51 %, and 9.11% of the total variance in depth to groundwater level in the western, central, and northern parts study areas, respectively. The projection scenario in 2080 indicates a reduction in annual precipitation of about 23% yearly and an increase of about 2.4°C in temperature. The study’s significance in this field of research is presented in an analysis that gives an indepth understanding of the climatic change impacts and their influence on groundwater resources.

| summary | Jordan is considered the second poorest country worldwide regarding water resources, relying on groundwater as its primary water supply. The situation is worsened by climate change which affects the temperature and precipitation rate. Additionally, socioeconomically changes in Jordan have led to a sharp decline in water availability from 3600 m3/ca in 1964 to less than 150 m3/ca in 2005. Recent studies have mainly focused on surface waters, and there are still few studies investigating potential impacts on groundwater. Thus, this research was done to analyse the spatial-temporal effect of climate change in the Amman Zarqa basin (AZB) on precipitation, temperature changes, and groundwater depth over the past 30 years. Base maps, climatic and hydrological data such as daily temperature, precipitation and depth to groundwater level within time series at five climatic stations and wells in the AZB were analysed.
