Type III radio bursts in a fibrous coronaIt is shown that the effects of density variations in the solar corona may be comparable to or greater than other effects in producing the time and frequency profiles of Type III bursts. A quantitative treatment of the density inhomogeneity effect is presented and a simple mathematical theory that incorporates a log-normal distribution for density variations in nonradial diverging flux tubes is presented. This theory successfully simulates dynamic spectrograms of Type III bursts from 50 to 400 MHz.
