Title Modeling and assessing climatic trends
@inproceedings{Craigmile2017TitleMA, title={Title Modeling and assessing climatic trends}, author={Peter F. Craigmile}, year={2017} }
Climate studies often fit linear trends to data. In many cases simplifying assumptions such as independent errors and constant variance are used. We review a variety of approaches to estimating linear trends, and illustrate with US temperature data how oversimplified assumptions may lead to false significance. We outline a variety of methods to fit nonlinear trend models. Using the Berkeley Earth global data set we show that a bent cable fit is better than a linear fit for this series. We also…

A Dirichlet-based copula model is presented that is a flexible alternative to parametric copula models such as the normal and t-copula and fitted using a Bayesian framework that allow us to take into account different sources of uncertainty in the data and models.

This article presents a new procedure for long-lead forecasting of tropical Pacific SST fields that expresses qualitative aspects of scientific paradigms for SST dynamics in a statistical manner and acquires considerable predictive skill.
A comparison study of extreme precipitation from six different regional climate models via spatial hierarchical modeling
