不同波长初始电子密度扰动对扩展 F触发效应对比研究
A comparative study on the effects of different wavelengths of initial electron density disturbances on triggering spread-F
摘要
Abstract
Based on a physical model developed to present the development of the lower and mid-lati-tudes spread-F,the effects of different disturbances of electron density on triggering spread-F are compared and the evolution of plasma bubble and blob irregularities under different perturbation wavelengths of elec-tron density are discussed.The results show that no matter electron density is bubble or blob structure, the disturbances with short wavelength are much easier to trigger spread-F than long ones.When the initial disturbance with decreasing electron density exists in one side and increasing electron density disturbance appears in another side at the same time,the perturbation amplitude of each other will be much more en-hanced than that when they appear respectively,and the uplift rate of bubble structure is much faster than blob.Even if at the same level of electron density,the electron density bubble and blob structure do not al-ways be lifted or developed simultaneously and they do not always keep the same tendency.关键词
