Figure 5

Inter- and intra-climate model variability in the day of year of the beginning and end of the disagreement period in expected frost occurrence during spring across latitudes and 30-year periods. Solid lines represent the mean, and dashed lines the maximum and minimum DOY determining the beginning and end of the disagreement period in expected frost occurrence across latitudes. The disagreement period in expected frost occurrence refers to the period when the percentage of climate simulations expecting the occurrence of frost are < 90% and > 10% for the intra-climate model (internal variability) analysis and are < 80 and > 20% for the inter-climate model (difference between model formulations) analysis since it is during this period that climate simulations diverge the most in their expected frost occurrence. We used the ggplot2 library developed by Wickham²⁷ to produce the figure.
