Theoretical and numerical study on HF-induced ionospheric irregularities

WEI Han-ying ZHAO Zheng-yu NI Bin-bin (School of Electronic Information, Wuhan University, Wuhan Hubei 430079, China)  
This paper presents theoretical models for the formation of HF-induced ionospheric irregularities under both homogeneous and stratified ionosphere backgrounds. It proves theoretically that pondermotive force and thermal pressure play a lead role in the evolution of artificial irregularities during ionospheric heating. Based on the physical model for homogeneous ionosphere, spatial structures of HF-induced ionospheric irregularities are numerically obtained. The results demonstrate that electron density turbulences exhibit a typical scale of more than one kilometer in the pump field direction and of 10 to 20 meters in its perpendicular direction. These results match well with the experimental observations that artificial ionospheric irregularities usually hold a transverse scale of 10 meters and a longitudinal scale of one kilometer. The numerically obtained alternant structure of electron depletion and enhancement can also interpret self-focusing effect of radio waves during ionospheric heating processes.
