Climate Change Indicators In Alsheikh-Badr Basin (Syria)

Abstract

The trends and variability of climate change were studied through analyzing the trend of change in the annual temperature and rainfall averages during the period (1960 – 2016) in Al-Sheikh Badr Region by using Normal Distribution and De-Martonne index. The results showed a (-189 mm) linear decrease in the general trend of the rainfall, associated with a (+0.9o C) increase in the general trend of the temperature between 1960 and 2016. Also, Normal distribution showed that the probability of extreme temperatures events higher than 17.5oC increased from 3.3% during the period 1960-1990 to 24.8% during the period 1991-2016. While the probability of an extreme annual rainfall (more than 1800 mm) decreases from 5.3% to 4.7%, nevertheless, the probability of rainfall events less than 800mm where increased. Furthermore, there is a significant trend of drought in the studied area, where the De-Martonne index reaches (-10.75) through the period (1960-2016).
