MetUM-GOML1 produces a weak and insignificant correlation between QBO winds and mean MJO amplitude in boreal winter, in contrast to the significant anti-correlation in reanalysis. While reanalysis shows the easterly QBO favors stronger Maritime Continent MJO activity, MetUM-GOML1 displays stronger West Pacific MJO activity. The biased QBO-MJO relationship in MetUM-GOML1 may be due to weak QBO-induced temperature anomalies in the tropical tropopause layer, or to errors in MJO vertical structure.
