A Method for Analysing Drifting Random Patterns in Astronomy and Geophysics. The Motion of the Solar Wind Close to the Sun,

摘要

The motion of interplanetary irregularities is derived in the range of solar elongation 6-40solar radii from observations of interplanetary scintillation using spaced receivers at the Goldstone Deep Space Tracking Station,California. The acceleration of the irregularities is found to be consistent with that predicted for a Parker solar wind model having a coronal temperature of about 1,000,000degrees K. There is evidence for high turbulent velocities of the irregularities which persist out to about 30solar radii and which account for the 'high frequency tails'in the scintillation spectra observed by other workers.
