Wave data assimilation using non-stationary kriging
نویسندگان
چکیده
We present a fast sequential assimilation technique for conditioning wave simulations using buoy data. It is based on non-stationary kriging that uses a separable space-time variogram. This variogram is estimated from the history of simulations, as a collection of maps of variances of increments between the logarithms of simulated and observed wave heights. The method finally provides a set of weights, that can be mapped for each buoy location, and that do not vary with time.

The major problems in modeling of different oceanographic and meteorological parameters are limitations in numerical methods and human incomplete knowledge in physical processes involved. As a result, significant differences between the results of these models and in situ observations of these parameters might exist. One of the powerful solutions for decreasing the forecast errors in the models...
متن کاملA non-stationary covariance-based Kriging method for metamodelling in engineering design
Metamodels are widely used to facilitate the analysis and optimization of engineering systems that involve computationally expensive simulations. Kriging is a metamodelling technique that is well known for its ability to build surrogate models of responses with non-linear behaviour. However, the assumption of a stationary covariance structure underlying Kriging does not hold in situations where...
متن کاملEstimation and prediction of a class of convolution-based spatial nonstationary models for large spatial data
In this paper we address two issues common to the analysis of large spatial datasets. One is the modeling of non-stationarity, and the other is the computational challenges in doing likelihood based estimation and kriging prediction. We model the spatial process as a convolution of independent Gaussian processes, with the spatially varying kernel function given by the modified Bessel functions....
متن کاملWavelets for Fast Bayesian Geophysical Interpolation
Seismic reflection, two-way time data is used to predict the extent and structural form of subsurface oil and gas reservoirs. Acoustic velocity data for the interval between the surface and the reservoir is variable and only available at sparsely and irregularly separated control points. To obtain an estimate of the actual reservoir structure in depth the velocity field must be mapped over the ...
متن کاملApplication of Data Assimilation to Three Dimensional Hydrodynamics the Case of the Odra Lagoon
A data assimilation scheme enables to correct a model estimate or rst guess of a physical state using measurements of the state variables The best estimate is given by minimization of the estimation variance as it is done in kriging In sequential data assimilation the spatial covariance of the rst guess error is propagated forward in time using the physical model and requires only the knowledge...
