Fig. 2: Climatological feature and MJO’s modulation on the daily mean rainfall and moisture flux convergence.

From: The impact of the Madden-Julian oscillation on spring and autumn afternoon diurnal convection in Sri Lanka

Fig. 2

Contours over the larger domain represent the horizontal distribution of the composites of the potential function of vertically integrated moisture flux (denoted as χQ; positive and negative values indicate convergence and divergence, respectively; units: kg·s −1) for strong MJO days in (a) spring and (b) autumn. The vectors and shaded areas represent the corresponding vertically integrated moisture flux vectors and daily mean rainfall, respectively. In c and d, the figures represent the difference between the composites at respective phase clusters (labeled) and the average of all eight MJO phases for spring and autumn, respectively. The left panel of each sub-figure provides a zoomed-in view of the rainfall distribution (shaded and contours) over Sri Lanka.
