Fig. 5: The CMJO episode linking to the Australian monsoon retreat.

From: Climatological Madden-Julian Oscillation during boreal spring leads to abrupt Australian monsoon retreat and Asian monsoon onsets

Fig. 5

Upper panels: OLR (shading, units in W m−2) and 850-hPa winds (vector, bold vectors indicate the wind speed (u2 + v2)1/2 > 0.5 m s−1, units in m s−1). The gray cross (circle) indicates a significant CMJO by the A/S (sign) test at the 95% confidence level. Lower panels: Longitudinal structures of the CMJO OLR (yellow bar) and 850-hPa zonal winds (red line, units in 5*m s−1), and 850-hPa specific humidity (blue line, units in 30*g kg−1). All variables are averaged over 10°S to EQ (purple dashed lines). Yellow thick arrows indicate the propagation direction of the OLR CISO signal from (a) P14 to (e) P18. f Red triangles and arrows indicate the centroids and propagation direction of the dry CMJO signal from P14 to P18, respectively.
