Abstract
A time series of Ca II K filtergrams of the chromosphere was used to study the relationship between correlation lifetimes and autocorrelation length s cales. The form of the lifetime-scale relation is inferred by comparing the distribution of the two parameters. A linear dependence of lifetime on cel l area, with a least squares fit slope of 3.34 x 10(7) km(2) hr(-1), is ded uced. The relation can be explained by assuming the network evolves by mean s of a diffusion process of the magnetic elements.
