THE 2ND-MOMENT CLIMATOLOGY OF THE GATE RAIN RATE DATA Academic Article uri icon

abstract

  • The first part of this paper presents the description of the GARP (Global Atmospheric Research Program) Atlantic Tropical Experiment 1 rain-rate data and its two-dimensional spectral and correlation characteristics, which have made it possible to show the concentration of a significant power along the frequency axis in the spatiotemporal spectra. The second part of this paper is devoted to an analysis of the diffusion of the rain rate by establishing a relationship between the parameters of the multivariate autoregressive model and the coefficients of a diffusion equation. This analysis led to the use of rain data to estimate the rain advection velocity as well as other coefficients of the diffusion equation of the corresponding field. -from Authors
