Significant strides have been made in understanding El Niño-Southern Oscillation (ENSO) dynamics, yet its long-lead prediction remains challenging, especially for the El Niño events after 2000. Sea surface salinity (SSS) is known to affect ENSO development ...

Severe marine heatwave over the North Pacific was observed in spring 2020, which likely caused the record Arctic ozone loss. Here we show that this anomalous North Pacific warming is related to the emission reductions during COVID-19 which emerged in China ...

Observational data and numerical models suggest that, under climate change, elevated land surfaces warm faster than non-elevated ones. Proposed drivers of this "elevation-dependent warming"(EDW) include surface albedo and water vapour feedbacks, the temper ...

The tropical Pacific warming pattern since the 1950s exhibits two warming centers in the western Pacific (WP) and eastern Pacific (EP), encompassing an equatorial central Pacific (CP) cooling and a hemispheric asymmetry in the subtropical EP. The underlyin ...
