Fig. 1: The signal-to-noise ratio of low-to-no-snow emergence.
From: Asymmetric emergence of low-to-no snow in the midlatitudes of the American Cordillera
a, American Cordillera (black polygons) from 60° N to 60° S. Lines at ±32° latitude and country borders are shown in grey. b, Latitude band averages of annual peak SWE percentiles within the American Cordillera as simulated by the highest-resolution (20 km) HighResMIP simulation (MRI-AGCM3-2-S) over 1950–2100 under the high-emissions shared socio-economic pathway (SSP5-8.5). The top x axis shows the annual mean global surface air temperature anomalies, and the bottom x axis indicates the years between 1950 and 2100. The years 1950–2000 are used as the historical reference period to compute percentile bins and annual mean temperature anomalies. White regions indicate annual peak SWE values ≤2.54 mm or no SWE. Low-to-no-snow conditions are defined as latitude band average annual peak SWE ≤30th percentile.
