Abstract Rapid warming has led to an aggregated environmental degradation over the Tibetan Plateau (TP) in last few decades, including accelerated glacier retreat, early snowmelt, permafrost degradation, and forest fire occurrence. Attribution of this recent decades mainly been focused on anthropogenic forcing. Yet, linkages Atlantic multidecadal variability (AMV), essential part climate system causing decadal centennial fluctuations temperature, remains poorly understood for TP, especially...
Abstract This paper investigates the impact of South China Sea summer monsoon (SCSSM) on Indian Ocean dipole (IOD). The results show that SCSSM has a significant positive relationship with IOD over boreal [June–August (JJA)] and fall [September–November (SON)]. When is strong, enhanced southwesterly winds bring more water vapor to western North Pacific (WNP) lead surplus precipitation in WNP, inducing anomalous ascending there. Consequently, descending branch Hadley circulation (SCSSMHC)...
Abstract The interactions between El Niño‐Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) are known to have great implications for global climate variability seasonal predictions. Observational analysis suggests that the ENSO–IOD inter‐basin connection is time‐varying related Atlantic Multidecadal (AMO) with weakened relationship corresponding AMO warm phases. A suite of pacemaker simulations successfully reproduces decadal fluctuations in its link AMO. sea surface temperature...
Abstract Time-slice experiments with the Whole Atmosphere Community Climate Model, version 4 (WACCM4), and composite analysis satellite observations are used to demonstrate that Indo-Pacific warm pool (IPWP) can significantly affect lower-stratospheric water vapor. It is found a warmer IPWP dries stratospheric vapor by causing broad cooling of tropopause, vice versa for colder IPWP. Such imprints in tropopause temperature driven combination variations Brewer–Dobson circulation stratosphere...
Abstract A new air‐sea coupled mode is discovered off the coast of northern Chile and named Niño/Niña. It shows remarkable interannual variability in sea surface temperature (SST) with peak austral summer from January to March. The related warm (cold) SST anomalies are mainly generated by anomalous southward (northward) alongshore winds that suppress (enhance) coastal upwelling subsurface mixing and, turn, reinforce wind heating (cooling) overlying atmosphere strengthening cross‐shore...
Austral summer (December–February) surface air temperature over southeast Australia (SEA) is found to be remotely influenced by sea (SST) in the South Atlantic at decadal time scales. In austral summer, warm SST anomalies southwest induce concurrent above-normal SEA. This decadal-scale teleconnection occurs through eastward propagating Atlantic–Australia (SAA) wave train triggered Atlantic. The excitation of SAA verified forcing experiments based on both linear barotropic and baroclinic...
In this study, the interhemispheric sea surface temperature (SST) signature of Atlantic Multidecadal Oscillation (AMO) is analyzed and compared between observations slab ocean model (SOM) simulations. Observational analysis suggests a robust SST dipole across associated with AMO, manifested by strong inverse relationship AMO subpolar South decadal anomalies. None SOMs could reproduce observed AMO; instead, they consistently simulate an coherent pattern. SOMs, North anomalies synchronize...
Abstract Sea surface temperature (SST) in the midlatitude south Indian Ocean (MSIO) exhibits prominent multidecadal fluctuations that have profound climate impacts for regions around Ocean. Observational analysis suggests these can be explained by remote forcing from South Atlantic variability. A suite of Pacemaker experiments performs well reproducing observed MSIO SST variation and its association with Atlantic. This transbasin covariability described an atmospheric bridge mechanism, which...
Abstract Global sea surface temperature (SST) evolution exhibits an antiphase variation between the two hemispheres that is referred to as SST interhemispheric dipole (SSTID) mode. The impacts of SSTID on extratropical atmospheric circulation in boreal winter are explored by both regression analysis and SST-forced numerical simulations. responses thermal forcing bear equivalent barotropic structure. For Southern Hemisphere (SH), positive events lead a meridional dipolar perturbation level...
Abstract The atmospheric perturbation potential energy (PPE) over the tropical Pacific is calculated and analyzed in a composite ENSO cycle. PPE troposphere increases during El Niño decreases La Niña, displaying two centers symmetrical about equator delaying central–eastern SST anomaly by months. Generated from diabatic heating, smaller part of lower varies synchronously with through sensible while larger lies mid- upper lags one season because latent heat release. As peaks boreal late...
Abstract The sea surface temperature inter-hemispheric dipole (SSTID) is an important variability mode of global SST anomalies, characterized by anti-phase variation between the two hemispheres. In this study, decadal northern hemisphere summer monsoon (NHSM) found to be strongly regulated SSTID, with positive (negative) phases SSTID corresponding strengthening (weakening) NHSM. Both observation and SST-forced atmospheric model simulations suggest that related thermal forcing modulates NHSM...
Abstract This study systematically evaluated global tropical cyclone (TC) activity in a new atmospheric reanalysis dataset named the “40‐year Global Reanalysis” (CRA40) against best track data. For comparison, four state‐of‐the‐art reanalyses—ERA5, JRA55, CFSR, and MERRA2—were also assessed. The results showed that there is general underestimation of TC genesis frequency intensity both CRA40 other reanalyses. A detailed investigation spatial distribution, seasonality, interannual variation,...
The relationship between Indo-Pacific convection oscillation (IPCO) and summer (June-August) surface air temperature in southern Asia (including India Indochina) is investigated for the period of 1979-2013 using observational datasets a theoretical linear baroclinic model. In summers with positive IPCO phase, when over western North Pacific (north Indian Ocean) enhanced (suppressed), Southeast Asian monsoon cooler than usual, vice versa. “positive-negative-positive” advection anomalies by...
Based on 35-year (1981–2015) ensemble (24 members) hindcasts of the IAP/LASG global seasonal prediction system named FGOALS-f2 V1.0 (FGOALS-f2), tropical cyclone (TC) skills over South China Sea (SCS) during TC peak season (July–November) are evaluated. Starting from June 20th, can well capture mean characteristics for both genesis location and track TCs SCS. For anomalous numbers, underestimates maximum minimum number compared to observation. The temporal correlation coefficients (TCCs)...
This study investigates the energy conversion processes and their relation to convection (circulation) during South China Sea summer monsoon (SCSSM) years from viewpoint of atmospheric perturbation potential (PPE). An PPE dipole pattern associated with SCSSM develops over western North Pacific (WNP) southern Maritime Continent (SMC) in boreal summer, serving as a link between diabatic heating. Actually, variations WNP is distinctly different that SMC. The precipitation leads WNP, while...
Abstract Under global warming, surface air temperature has risen rapidly and sea ice decreased markedly in the Arctic. These drastic climate changes have brought about various severe impacts on vulnerable environment ecosystem there. Thus, accurate prediction of Arctic becomes more important than before. Here we examine seasonal to interannual predictive skills 2-m (2-m T ) cover (SIC) over region (70°–90°N) during 1980–2014 with a high-resolution coupled model called Met Office Decadal...
Abstract As a dominant climate mode of the southeast Indian Ocean, Ningaloo Niño/Niña has paramount impacts on regional and marine ecosystems. Using outputs from latest phase Coupled Model Intercomparison Project (CMIP6), we have systematically evaluated simulation in state‐of‐the‐art coupled models. Eighteen out 28 CMIP6 models well reproduce spatial pattern seasonality Niño/Niña, whereas simulated amplitudes show large spread across Main processes oceanic atmospheric El Niño‐Southern...
