Ionosphere is the ionized division of earth's upper atmosphere which acts as a refractor and rflector for high frequency from 3-30 MHz radio waves. the ionospheric region for HF communication is situated about 80-1500 km from sea surface. this potion of uppere atmosphere as a whole is an open system that regarded as a nonlinear system. in this research we have computed turbulence in upper atmospheric plasma. Sun's magnetic field causing geomagnetic and ionospheric turbulence.
