Predicting the Impact of Global Warming on the Middle East Region: Case Study on Hashemite Kingdom of Jordan Using the Application of Geographical Information System

Mohammed Matouq    

Abstract: This study intends to analyze the metrological data like rain fall, temperature and humidity obtained from Jordanian metrological department, covering the period of 1955-2002. These obtained data were analyzed using the Geographic Information System (GIS) and converted into geographical maps. Three different parameters were investigated temperatures annual mean maximum and annual mean minimum, the average annual rainfall and the average annual relative humidity. The results show that no change in the average annual rainfall in both northern and eastern part of the kingdom, while it has been increases in the middle region of the kingdom. Although local temperatures fluctuates naturally, but over the past 50 years the average local temperature in Jordan has increased at very rapid rate since 1990 and it reached an elevation in temperature up to about 1.5-2°C. It is noticed that the global warming impact on Jordan weather has been started after the 1991, in which the phenomena of the global warming was noticed to have its impacts worldwide since that date. Due to the predicted increase in both maximum and minimum temperatures in some regions, the rate of evaporation will also tends to increase and hence higher relative humidity will be expected in that regions. The application of GIS in this analytical study was successfully used to analyze the data and to produce maps easy to understand the impact of global warming. GIS also helps to calculate the exact area where region experienced a change in temperature and or rain falls. This application will be the first in its application in Jordan at country level. The result will be in a great help for those in decision making in the field of environment.
