E xtremes: S patial M odels and P rediction

Abstract

Max‐stable processes and fields are reviewed as natural models of spatial extremes. Their stochastic properties, extremal integral, and de Haan spectral representations are briefly discussed. A solution to the prediction problem for a large class of spectrally discrete max‐linear models is presented and illustrated over a data set of rainfall extremes.

Ludendorff coronal flattening index of the total solar eclipse on March 9, 2016

“…One way to quantify the global structure of the corona is using Ludendorff coronal flattening index ( ) [6]. Several studies calculated coronal flattening index for TSE event have been conducted [7,4,3,8,6,9]. From the compilation of measurements, variation of coronal flattening index over solar cycle can be modeled and the characteristics of upcoming solar cycle (e.g.…”
