[图6(b)中2017年10月31日至2018年2月27日RMM指数为监测值,2018年2月28日至4月18日为预报值,箭头表示纬向风距平和RMM指数传播方向]
Fig.6 The MJO phase from December 23, 2017 to February 5, 2018 (a) and time-longitude cross section of 850 hPa zonal wind anomaly (color shaded areas) and RMM index (isoline) averaged from 15°S to 15°N(b, Unit: m·s-1
[RMM index from October 31, 2017 to February 27, 2018 were monitoring value, while RMM index from February 28 to April 18, 2018 was forecast value, the arrow denotes zonal wind anomaly and RMM index propagation direction in fig.6 (b)]
