Spatial persistence in wind analysis

Spatial wind distributions are of high interest in many environmental and economic fields. The diversity of elements, geophysical frameworks and methodologies involved in wind spatial studies makes difficult the comparison among approaches, 'blurring' their contributions. This paper proposes an easy-to-implement model, inspired in the 'persistence' model used in wind forecasting, that can be used as reference in wind spatial studies. The main purpose is to provide a context in which both the difficulty of the concerned problem and the contribution of the applied model can be characterized, allowing the comparison among different studies.
