This study examines changes in annual and seasonal mean (minimum and maximum)temperatures variations in Jordan during the 20 th century. The analyses focus on the time series recordsat the Amman Airport Meteorological (AAM) station. The occurrence of abrupt changes and trendswere examined using cumulative sum charts (CUSUM) and bootstrapping and the Mann-Kendall ranktest. Statistically significant abrupt changes and trends have been detected. Major change points in themean minimum (night-time) and mean maximum (day-time) temperatures occurred in 1957 and 1967,respectively. A minor change point in the annual mean maximum temperature also occurred in 1954,which is essential agreement with the detected change in minimum temperature. The analysis showed asignificant warming trend after the years 1957 and 1967 for the minimum and maximum temperatures,respectively. The analysis of maximum temperatures shows a significant warming trend after the year1967 for the summer season with a rate of temperature increase of 0.038°C/year. The analysis ofminimum temperatures shows a significant warming trend after the year 1957 for all seasons.Temperature and rainfall data from other stations in the country have been considered and showedsimilar changes. |
