Extended Data Fig. 5: Trend in specific humidity anomalies.
From: Twofold expansion of the Indo-Pacific warm pool warps the MJO life cycle

Trend in specific humidity anomalies (g kg−1 per 38 years) for November–April, during 1981–2018. The trends indicate an increase (red colours) in tropospheric moisture over the warm pool region and a reduction (blue colours) in tropospheric moisture over the Indian Ocean (900–400 hPa levels).
