In this project,the behavior of ionospheric parameters has been studied for the seasonal times of the years (2009 & 2014) of solar cycle 24.A mutual correlation formula between the ionospheric parameters, maximum usable frequency (MUF), optimum workable frequency (OWF) & lowest usable frequency (LUF) have been suggested for the communication links distributed over Middle East Region. The values of the MUF and OWF parameters were generated from the international communication HF model (ASAPS) for the Minimum and Maximum of solar cycle 24, While the LUF parameter was generated using the (REC533) international communication model. The tested correlation coefficients between these parameters showed a good correlation with each other. The suggested formula gave a good fitting between the present values and the generated data of the international model and the international recommended criterion (theoretical).
