This research aims to study the effect of the solar activity on the correlation between the electron temperature Te with both maximum peak height hmF2 and the maximum electron density Nemax for F2 region. The data used has been obtained using the International Reference Ionosphere IRI-2012 model which gives overall description of ionospheric parameters. The results show that the effect of high solar activity on the cross correlation coefficient (CCC) of (Tewith hmF2) has an intangible change at equator and no correlation will control it, while for other latitudes, the high solar activity try to shift the CCC from negative to no correlation especially at high latitudes. The second correlation (Te with Nemax), CCC at equator change from positive correlation to no correlation. For mid latitude, the process is opposite. Finally, for high latitude, the process is a typical for an equator.
