    "abstract": "We present results from the sixth stage of a project to build a statistical\nhurricane model. Previous papers have described our modelling of the tracks,\ngenesis, and lysis of hurricanes. In our track model we have so far employed a\nnormal distribution for the residuals when computing innovations, even though\nwe have demonstrated that their distribution is not normal. Here, we test to\nsee if the track model can be improved by including more realistic non-normal\ninnovations. The results are mixed. Some features of the model improve, but\nothers slightly worsen.",
