+    Wind simulation in the context of ship motions is used to estimate the
+    effect of the wind on large containerships, sailboats and yachts. Wind
+    models are typically based on a sum of harmonics with random phases and
+    different amplitudes.  In this paper we propose to use autoregressive model
+    to simulate the wind. This model is based on autocovariance function that
+    can be estimated from the real-world data collected by anemometers.  We
+    have found none of the data that meets our resolution requirements, and
+    decided to produce the dataset ourselves using three-axis anemometer.  We
+    built our own anemometer based on load cells, collected the data with the
+    required resolution, verified the data using well-established statistical
+    distributions, estimated autocovariance functions from the data and
+    simulated the wind using autoregressive model. We have found that the load
+    cell anemometer is capable of recording wind speed for statistical studies,
+    but autoregressive model needs further calibration to reproduce the wind
+    with the same statistical properties.
