- Does Wind Affect the Orientation of Vegetation Stripes? A Copula‐Based Mixture Model for Axial and Circular Data Marco Mingione Francesco Lagona Priyanka Nagar Francois von Holtzhausen Andriette Bekker Janine Schoombie Peter C. le Roux Environmetrics ABSTRACTMotivated by a case study of vegetation patterns, we introduce a mixture model with concomitant variables to examine the association between the orientation of vegetation stripes and wind direction. The proposal relies on a novel copula‐based bivariate distribution for mixed axial and circular observations and provides a parsimonious and computationally tractable approach to examine the dependence of two environmental variables observed in a complex manifold. The findings suggest that dominant winds shape the orientation of vegetation stripes through a mechanism of neighboring plants providing wind shelter to downwind individuals. 10.1002/env.70021 http://onlinelibrary.wiley.com/termsAndConditions#vor
