During 2010 to 2020, Northeast Pacific (NEP) sea surface temperature (SST) experienced the warmest decade ever recorded, manifested in several extreme marine heatwaves, referred as “warm blob” events, which severely affect ecosystems and weather along west coast of North America. While year-to-year internal climate variability has been suggested a cause individual causes continuous dramatic NEP SST warming remain elusive. Here, we show that other than greenhouse gas (GHG) forcing, rapid...
Abstract The seasonal delay of tropical rainfall is a robust feature under global warming. This study finds that the much more pronounced spatially patterned sea surface temperature (SST) warming compared to uniform SST Through lens atmospheric energetic framework, we show enhanced primarily driven by interhemispheric contrast in between Northern and Southern Hemispheres, which intensifies inter‐seasonal difference cross‐equatorial energy transport transition seasons. features are found be...
Abstract The future tropical sea surface temperature (SST) changes profoundly impact global and regional climate. Under greenhouse warming, the reduction of Antarctic ice concentration (SIC) acts as an extratropical energy perturbation, exerting a substantial influence on spatial distribution SST change. This study reveals strong correlation between current SIC change, especially interhemispheric asymmetry El Niño‐like pattern under warming among CMIP6 models. Considering commonly...
Abstract Tropical climate response to greenhouse warming is first order symmetric about the equator but models disagree on degree of latitudinal asymmetry tropical change. Intermodel spread in equatorial investigated by using 37 from phase 6 Coupled Model Intercomparison Project (CMIP6). In simple simulation with CO 2 increase at 1% per year without aerosol forcing, this study finds that intermodel tied extratropical surface heat flux change related Atlantic meridional overturning...
Abstract Anthropogenic aerosols, concentrated largely in the Northern Hemisphere, not only affect local climate but also induce pronounced changes atmospheric circulation that extend into Southern Hemisphere (SH). In coupled historical single‐forcing simulations, aerosol forcing induces a deceleration of both subpolar jet (SPJ) and subtropical (STJ) SH austral winter. Atmospheric general model experiments indicate STJ is weakened by an interhemisphere gradient zonal mean sea surface...
Abstract Tropical precipitation change under global warming varies with season. The present study investigates the characteristics and cause of seasonality in rainfall change. Diagnostically, tropical is decomposed into thermodynamic dynamic components. component represents wet-get-wetter effect its due mostly to that mean vertical velocity, especially monsoon regions. includes warmer-get-wetter spatial variations sea surface temperature (SST) warming, while climatological SST can be largely...
Abstract A deep winter mixed layer forms north of the Antarctic Circumpolar Current (ACC) in Indo-Pacific sectors, while depth (MLD) is shallow Atlantic. Using observations and a global atmospheric model, this study investigates contribution surface buoyancy flux background stratification to interbasin MLD variations. The heat decomposed into broad-scale frontal-scale At broad scale, meandering ACC path accompanied by zonal wavenumber-1 structure sea temperature (SST) with warmer Pacific...
Abstract Global climate models generally project a robust decline in Antarctic sea ice (ASI) under increased atmospheric carbon dioxide (CO 2 ) while an ASI expansion has been observed over the recent four decades. Motivated by apparent model‐observation discrepancy, this study investigates influences of change on global warming pattern exploiting spread across from Phase 6 Coupled Model Intercomparison Project (CMIP6). The results indicate close intermodel relationship between and surface...
The Southern Ocean features some of the deepest winter mixed layers on Earth, crucial for water mass formation and storage anthropogenic heat. layer depth (MLD) significantly varies across basins, exceeding 300 m in Indian Pacific sectors but less than 150 Atlantic. Current climate models simulate a distribution that is too broad struggle to accurately represent this inter-basin variation. Using observational data global atmospheric model, study investigates contribution surface buoyancy...
