Erratum: Ocean warming pattern effects on future changes in East Asian atmospheric rivers (Environmental Research Letters (2019) 7 (054019) DOI: 10.1088/1748-9326/ab128a)

Abstract

In Kamae et al (2019), we made mistakes explaining the method for detecting atmospheric rivers (ARs) in the global warming simulations. The anomalies in vertically integrated water vapor transport (IVT) used in the AR detection were calculated by subtracting IVT climatology in the global warming simulations, not IVT climatology in the current climate simulation. Section 2.2 ‘Future projection’ 1st paragraph, the last sentence should read ‘The AR detection scheme described in section 2.1 and used in Kamae et al (2017b) was applied to the outputs of global warming simulation. Note that the IVT anomaly used in the AR detection was calculated by subtracting IVT climatology in the global warming simulations.’. Section 3.1 ‘AR response to climate warming’ 1st paragraph, the last two sentences ‘The general increasing trend of ARs under climate warming can be attributed to thermodynamic effect (e.g. Lavers et al 2013, Gao et al 2015). Atmospheric water vapor increase and resultant positive ?IVT should result in more AR count because the anomalous IVT threshold (section 2.1) is identical between current climate and global warming simulations.’ were incorrect and should be skipped. Section 4 ‘Summary and discussion’ 1st paragraph, the second and third sentences should read ‘Generally, ARs become more frequent over the Northern Hemisphere including summertime East Asia increasing trend, dynamic effect is important for the spreads of East-Asian ?ARs among different SST warming experiments via changing atmospheric circulation patterns over the Indo-Pacific region.’. The corrections do not affect the major conclusions of the paper.
