Joint dependence of ΔP on (V m, \(\frac{1}{2}f{r_8}\)) across simulations and observations. a OMEGA; binned MLR fit \(\Delta {P_{{\rm{bin}}}} = - 25.9 + 1.82({V_{\rm{m}}}) + 0.46(\frac{1}{2}f{r_8})\) (\({r^2} = 0.97,\;{N_{{\rm{bin}}}} = 528,\;{\epsilon _{{\rm{RMS}}}} = 4.9{\kern 1pt} {\rm{hPa}}\)). b AMIP; binned MLR fit \(\Delta {P_{{\rm{bin}}}} = - 25.2 + 1.77({V_{\rm{m}}}) + 0.57(\frac{1}{2}f{r_8})\) (\({r^2} = 0.96,\;{N_{{\rm{bin}}}} = 641,\;{\epsilon _{{\rm{RMS}}}} = 5.5{\kern 1pt} {\rm{hPa}}\)). c Observations; binned MLR fit \(\Delta {P_{{\rm{bin}}}} = - 26.2 + 1.55({V_{\rm{m}}}) + 0.64\left( {\frac{1}{2}f{r_8}} \right)\) (\({r^2} = 0.92,\;{N_{{\rm{bin}}}} = 281,\;{\epsilon _{{\rm{RMS}}}} = 7.8{\kern 1pt} {\rm{hPa}}\)). Data are binned into 2.5 ms−1 increments increasing from zero for each parameter, with the median value of ΔP displayed in each bin (color). Black lines denote lines of constant ΔP with contour interval of 5 hPa. Purple lines denote bin count for N = [10, 100, 1000] for simulations and N = [3, 9, 27] for observations. All bins containing at least one data point are plotted
