Fig. 4From: Change in trade wind inversion frequency implicated in the decline of an alpine plantEstimated precipitation patterns as a function of elevation within silversword habitat. Points represent estimated values for each 250 m grid cell overlapping the silversword range. (a) Annual rainfall averages for 1920–1990 and 1991–2012, (b) difference between 1920 and 1990 and 1991–2012 averages for each cellBack to article page
