  Problem Statement: Jordan is experiencing harsh water shortage in different parts of the country due to high fluctuations in annual precipitation; the only source of water. In addition, heat waves are becoming more frequent in the region. Precipitation decrement and summer heat waves are being blamed on global warming. This study aimed to detect trends in weather parameters in Jordan. Approach: Data from six meteorological stations distributed around Jordan were analyzed using several parametric and nonparametric statistical approaches including Mann-Kendall, Linear Regression, Cusum, Rank Sum, Student's t-test, Rank Difference, Auto Correlation and Skewness-Kurtosis Normality test. Results: The results indicated that there are no visible trends indicating an increase or decrease in the annual precipitation and maximum temperature. However, there are good to strong trends indicating that annual minimum temperature has increased in the last decade while annual temperature range has decreased. Conclusion: Decreasing temperature range proved that the Earth’s atmosphere is becoming more efficient in trapping terrestrial infrared radiation, which is accountable for the global warming.

  In this study, a new atomic physics program (HTAC) is introduced and tested. It is a utility program designed to automate the computation of various atomic structure and spectral data. It is the first comprehensive code that enables performing atomic calculations based on three advanced theories: the fully relativistic configuration interactions approach, the multi-reference many body perturbation theory and the R-Matrix method. It has been designed to generate tabulated atomic data files that can be interfaced with other programs in a simple and straightforward manner. It works for all known elements in the periodic table and their ions. Generated atomic structure data includes energy levels, oscillator strength, radiative transition rates, mixing coefficients for any rank of multipole transitions and other quantities. It provides a user friendly interface that works under windows in the dialog mode. Its Graphical User Interface (GUI) clarifies analysis steps and handles file manipulations required by the used model. In addition, the GUI provides viewing and plotting capabilities of the generated atomic data. Furthermore it will be distributed freely.
