On the Potential of 25 Years (1991–2015) of Rawinsonde Measurements for Elucidating Climatological and Spatiotemporal Patterns of Afternoon Boundary Layer Depths over the Contiguous US

Figure 13

Box-and-whisker analyses of the climatological averages of summer (a) and winter (b) PBL depths aggregated by climate class. Two different maximum -axis scale limits were used for summer (4000 m, panel (a)) and winter (2000 m, panel (b)) seasons to illustrate PBL depth variability within a given season. All the available summer and winter monthly mean values of PBL depths over the sites located within each climatic region are considered.
