      Maxima for Gaussian seas 

      Baxevani, Anastassia; Rychlik, I. (2006)
      The probability distribution of the height of global maximum for a Gaussian random field evolving in time is studied. In particular, the effect of spreading is studied and the role of the wave kinematics is discussed. It ...

      Modelling significant wave height in the North Atlantic 

      Baxevani, Anastassia; Rychlik, I.; Wilson, R. J. (2003)
      The surface of the ocean, and so such quantities as the significant wave height, can be thought of as a random surface in space which develops over time. In this paper, we explore certain types of random fields (in space ...

      A new method for modelling the space variability of significant wave height 

      Baxevani, Anastassia; Rychlik, I.; Wilson, R. J. (2005)
      Significant wave height, Hs, is a measure of the variability of the ocean surface and is defined to be four times the standard deviation of the height of the ocean surface. In this paper, we present a methodology for ...

      Relation between velocities and global maximum for Gaussian seas 

      Baxevani, Anastassia; Rychlik, I. (2004)
      We study the probability distribution of the height of global maximum for a Gaussian random field evolving in time. Particularly, we discuss the role of the wave kinematics. It is observed that taking into account time ...

      Spatial models for the variability of the significant wave height on the world oceans 

      Baxevani, Anastassia; Borgel, C.; Rychlik, I. (2007)
      Significant wave height (Hs) is a measure of the variability of the ocean surface. Knowledge of the spatial and temporal characteristics of this field are multiple: it is useful to dimension offshore structures, to foresee ...

      Spatial models for variability of significant wave height in world oceans 

      Baxevani, Anastassia; Borgel, C.; Rychlik, I. (2008)
      Significant wave height (Hs) is a measure of the variability of the ocean surface. Benefits from knowing the spatial and temporal characteristics of this field are multiple: It is useful to size offshore structures, to ...

      Spatio-temporal statistical modelling of significant wave height 

      Baxevani, Anastassia; Caires, Sofia; Rychlik, I. (2009)
      In this paper, we construct a homogeneous spatio-temporal model to describe the variability of significant wave height over small regions of the sea and over short periods of time. Then, the model is extended to a ...
