WebSep 28, 2024 · The tropical Pacific SST biases in the newer CMIP6 models are smaller on average than those in the CMIP5 models (see Fig. S1). ... The equatorial cold SST bias also leads to the rising branch of the Walker circulation being shifted to the west, weakening atmospheric feedbacks (Bayr et al., 2024). South of the Equator, there is a wet bias in … WebApr 10, 2024 · Through comparison between 2024 and 2024 HistoricalExt ensemble (the only difference between them is the specified 2024 and 2024 observed SST), we find SST pattern in 2024 has increased the ...

WebAug 24, 2024 · However, both the seasonal cold bias and warm bias are considerably decreased for CMIP6, which leads the annual SST cycle to more closely reflect the observation. For the CMIP6 MME SST simulation in EP2, the amplitude is similar to the observed value due to the quasi-constant cold bias throughout the year, although the …
WebApr 10, 2024 · We further explore the relationship between the Northwestern Pacific (10°–30°N, 110°–160°E) SST bias and East Asian 850 hPa wind skill in CMIP5 and CMIP6 models (Figure 5b). It is shown that CMIP6 MME has less NWP SST bias than the CMIP5 MME. The model spread of NWP SST bias is much less than that in the CMIP5 models. WebJun 8, 2024 · The biases in SST seasonal extrema are largely consistent with the annual mean SST biases. However, the amplitude and spatial pattern of SST bias vary …
WebThe biases in SST seasonal extrema are largely consistent with the annual mean SST biases. However, the amplitude and spatial pattern of SST bias vary seasonally in the 20 CMIP6 models assessed. Large seasonal variations in the SST bias occur in eastern boundary upwelling regions, polar regions, the North Pacific and the eastern equatorial ... WebAug 17, 2024 · Although the positive ENSO-related SST anomaly bias in the EWP still exists in the CMIP6 MME (Figs. 7 c and 7 e), the simulated ENSO-related SST pattern in CMIP6 MME are closer to observations than that in CMIP5 MME (Figs. 7 a − c), and the magnitude of this bias in the CMIP6 MME has been significantly reduced relative to the …
WebJul 1, 2024 · Furthermore, the seasonal cycle of the zonal SST gradient along the equator can explain approximately 24% and 27% of the variance in the ENSO phase-locking for CMIP5 and CMIP6, respectively. In particular, the strengths of the zonal SST gradient in the central-eastern Pacific during boreal spring and autumn are crucial.
