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 7

Spatial variability of PBL depth over different sectors of the contiguous US, illustrating low seasonal scale amplitudes of PBL depths (<300 m) over Northern Great Plains (b), Upper Midwest (c), Northeast (f), and Southeast (g) regions, relatively higher amplitudes (>1000 m) over Northwest (a) and Southwest (e) regions, and moderate seasonal scale amplitude over Southern Great Plains (d). Seasonal scale amplitudes were determined by subtracting median winter PBL depths from summer median PBL depths. Stars indicate mean; horizontal line represents median; boxes indicate the 25th and 75th percentiles; X’s indicate 10th and 90th percentiles.
