Marine heatwaves (MHWs) in the Northwest Pacific (NWP) exert significant ecological and climatic impacts, yet their drivers and predictability are not fully understood. Based on the multivariate empirical orthogonal function (MV‐EOF) method, this study identifies two dominant modes of summer NWP MHWs. The first mode, characterized by widespread war...

Aerosols of anthropogenic origin exhibit significant spatial variability, leading to localized environmental pollution and climate effects. The increasing international trade has caused extensive cross-border transfer of pollution, rendering the traditional production-based perspective insufficient for assessing the climate impacts of human activit...

Multiscale oceanic motions continuously transfer kinetic energy across various spatiotemporal scales through kinetic energy cascade. Satellite altimetry offers long-term daily ocean data at 0.25-degree resolution, enabling the analysis of energy cascades in both wavenumber and frequency domains. While energy cascade studies in the wavenumber domain...

A “stilling” or “reversal” of surface wind speed (SWS) trend over the landmass of the Northern Hemisphere has been observed during the past decades, with notable regional disparities. In particular, the reversal of SWS in Northeast China is observed in 2010, which is different to the features over other regions such as North China (reversal in 2006...

Distinct Pacific-North American (PNA) teleconnection patterns and their associated climate impacts in North America have been observed during single-year El Niño events, as well as during both the first and second years of multi-year El Niño events. The research highlights the critical role of PNA-related North Pacific circulation anomalies, which...

Plain Language Summary The principal origins of South Asian summer monsoon (SASM) interannual variability are rooted in the combined modulation of three tropical oceans, which challenges its prediction due to complex multi‐ocean interactions. Atmospheric heat sources, however, can directly impact SASM, acting as a bridge connecting sea surface temp...

Accurate sub-seasonal (2-8 weeks) prediction of monsoon precipitation is crucial for mitigating flood and heatwave disasters caused by intra-seasonal variability (ISV). However, current state-of-the-art sub-seasonal-to-seasonal (S2S) models have limited prediction skills beyond one week when predicting weekly precipitation. Our findings suggest tha...

Besides, the extre...

Atmospheric rivers (ARs) reaching high-latitudes in summer contribute to the majority of climatological poleward water vapor transport into the Arctic. This transport has exhibited long term changes over the past decades, which cannot be entirely explained by anthropogenic forcing according to ensemble model responses. Here, through observational a...

As the carbon-neutral target has been set, it is of great importance to investigate and attribute dry-wet climate response for which CO2 emission is increasing, decreasing, and remaining stable over time.

Plain Language Summary The El Niño/Southern Oscillation (ENSO)‐induced atmospheric anomalies over the North Pacific and North America (PNA region) are more westward during La Niña relative to that during El Niño in boreal winter. The disparity of atmospheric responses causes discernible distinct climate implications, and limits the seasonal predict...

Understanding the multi-scale variabilities of global sea surface temperature (GSST) is extremely critical for deepening the comprehension of surface climate change. Great efforts have been made to study the multi-scale features of GSST, however, aiming to fully reveal the local features, here we propose a combined approach, incorporating an adapti...

El Niño-Southern Oscillation (ENSO) influences global weather and climate through teleconnection patterns. In tropical regions, ENSO can induce precipitation and sea surface temperature anomalies over remote ocean basins by influencing tropical tropospheric temperatures. In extratropical regions, ENSO can pose climate impacts over regions such as N...

The South Asian high (SAH), a large‐scale anticyclone at 100 and 200 hPa on the Asian continent, is driven by South Asian summer monsoon rainfall and heating over the Tibetan Plateau. As one member of the Asian summer monsoon system, the changes of its location and intensity may cause other climate responses. Rainfall‐induced latent heating can aff...

Using the daily maximum temperature and ECMWF Reanalysis v5 (ERA5) reanalysis data of 11 municipal meteorological stations in Inner Mongolia in summer, the comfort index (33.5°C), a high temperature threshold for the Inner Mongolia Region, was redefined by the percentile method and the Climatology method. The weather with maximum temperature ≥ 33.5...

In this study, the onset and cessation of rainy season over the Hengduan Mountains (HM) are determined by an objective method. The onset and cessation of climatological rainy season are largely controlled by large-scale circulation systems, such as the Indian summer monsoon (ISM), 200 hPa subtropical jet, and the South Asian high. Both onset and ce...

Recent decades have witnessed growing frequency and severity of catastrophic droughts in many regions of the world. Despite lots of studies having been dedicated to extreme drought investigation, the fundamental question that has long been ignored is: what is extreme drought? The answer is much more complex than first appears, because a critical is...

An anomalous anticyclone (AAC) recurs over the Indo-Northwest Pacific during post-El Niño summers, regulating climate anomalies in the densely populated South, Southeast, and East Aisa.

The reversibility of South Asian summer monsoon (SASM) precipitation under the CO 2 removal scenario is critical for climate mitigation and adaptation. In the idealized CO 2 ramp-up (from 284.7 to 1138.8 ppm) and symmetric ramp-down experiments, SASM precipitation is largely reversible while exhibiting strong asymmetry: it may overshoot the unpertu...

Weather forecasting has been playing an important role in socio-economics. However, operational numerical weather prediction (NWP) is insufficiently accurate in terms of precipitation forecasting, especially for heavy rainfalls.

Observations, theoretical analyses, and climate models show that the dominant timescale of multidecadal variability of the Atlantic Meridional Overturning Circulation (AMOC) is related to westward temperature propagations in the subpolar North Atlantic, which is modulated by oceanic baroclinic Rossby waves or thermal Rossby waves. Here, we find maj...

The Pacific–South America (PSA) teleconnection pattern triggered by the El Niño/Southern Oscillation (ENSO) is suggested to be moving eastward and intensifying under global warming.
