Sampling Geostatistical Structures in Extremal Framework

Geostatistics of extreme values makes it possible to model the asymptotic behavior random phenomena that depend on time or space. In this paper, we propose new models extremal coefficient a stationary field where cumulative distribution is associated with multivariate copula. More precisely, some extensions extremogram and these derivatives are built in spatial framework. Moreover, both two geostatistical tools modeled using variogram which characterizes stochastic phenomena.
