Fig. 6: Maps of projected change in low-level air stagnation days across the WUS, 2021–2060 vs. 1981–2020.
From: Climate change is narrowing and shifting prescribed fire windows in western United States
Maps depicting the projected change in the number of low-level air stagnation (LLS) days across the western United States (WUS) on an annual (a) and seasonal (b–e) basis. Here, positive values (blue regions) represent areas expected to see an increase in low-level air stagnation days. The change in projected stagnation days is calculated as the difference between the air stagnation day counts for 2021–2060 vs. 1981–2020 period on a “moderate warming” (RCP4.5) trajectory using meteorological data from the downscaled CMIP5 climate model dataset (MACA).
