Significance Marine and terrestrial proxy records suggest global cooling during the Late Holocene, following peak warming of Holocene Thermal Maximum (∼10 to 6 ka) until rapid induced by increasing anthropogenic greenhouses gases. However, physical mechanism responsible for this has remained elusive. Here, we show that climate models simulate a robust annual mean in mainly response rising CO 2 retreat ice sheets. This model-data inconsistency demands critical reexamination both data models.
Abstract This paper introduces the Flexible Global Ocean‐Atmosphere‐Land System Model: Grid‐Point Version 3 (FGOALS‐g3) and evaluates its basic performance based on some of participation in sixth phase Coupled Model Intercomparison Project (CMIP6) experiments. Our results show that many significant improvements have been achieved by FGOALS‐g3 terms climatological mean states, variabilities, long‐term trends. For example, has a small (−0.015°C/100 yr) climate drift 700‐yr preindustrial...
Abstract. The Last Glacial Maximum (LGM, 21 000 years ago) is one of the suite paleoclimate simulations included in current phase Coupled Model Intercomparison Project (CMIP6). It an interval when insolation was similar to present, but global ice volume at a maximum, eustatic sea level or close minimum, greenhouse gas concentrations were lower, atmospheric aerosol loadings higher than today, and vegetation land-surface characteristics different from today. LGM has been focus for Paleoclimate...
Abstract. The mid-Holocene (6000 years ago) is a standard time period for the evaluation of simulated response global climate models using palaeoclimate reconstructions. latest simulations are entry card Palaeoclimate Model Intercomparison Project (PMIP4) component current phase Coupled (CMIP6) – hereafter referred to as PMIP4-CMIP6. Here we provide an initial analysis and results experiment mid-Holocene. We show that state-of-the-art produce changes broadly consistent with theory...

New to Coupled Model Intercomparison Project (CMIP6) Tier 1 Last Interglacial experiment 127 000 years ago (lig127k), designed address responses stronger orbital forcing than midHolocene experiment, same state-of-the-art and following common experimental protocol. Here we present first analysis multi-model...
Abstract. El Niño–Southern Oscillation (ENSO) is the strongest mode of interannual climate variability in current climate, influencing ecosystems, agriculture, and weather systems across globe, but future projections ENSO frequency amplitude remain highly uncertain. A comparison changes a range past simulations can provide insights into sensitivity to mean state, including seasonality incoming solar radiation, global average temperatures, spatial patterns sea surface temperatures.

Understanding mechanisms for this response via climate modelling comparing models' representation of reconstructions one objectives set up by Paleoclimate Modelling Intercomparison Project its contribution to sixth phase Coupled Model Project. Here we analyse from 16 models terms Arctic sea ice. multi-model mean...
Short-term sea surface temperature (SST) forecasts are crucial for operational oceanology. This study introduced a specialized Transformer model (U-Transformer) to forecast global short-term SST variability and compare with those from Convolutional Long Short-Term Memory (ConvLSTM) Residual Neural Network (ResNet) models. The U-Transformer achieved root mean square errors (RMSEs) of 0.2–0.54 °C lead times 1–10 days during 2020–2022, anomaly correlation...
Abstract Controlled numerical experiments using ocean-only and ocean–atmosphere coupled general circulation models show that interannual sea level depression in the eastern Indian Ocean during dipole (IOD) events forces enhanced Indonesian Throughflow (ITF) to transport warm water from upper-equatorial Pacific Ocean. The produces elevation of thermocline cold subsurface temperature anomalies western equatorial Ocean, which propagate induce significant evolution tropical oceanic atmospheric...

Abstract. A high-resolution (1/20∘) global ocean general circulation model with graphics processing unit (GPU) code implementations is developed based on the LASG/IAP Climate System Ocean Model version 3 (LICOM3) under a heterogeneous-compute interface for portability (HIP) framework. The dynamic core and physics package of LICOM3 are both ported to GPU, three-dimensional parallelization (also partitioned in vertical direction) applied. HIP (LICOM3-HIP) 42 times faster than same number CPU...
Intelligent tunnel engineering requires accurate and comprehensive digital twin models to represent complex geological environments. The model of environment has multi-level diversified in-depth applications such as problem diagnosis, risk assessment, trend prediction, emergency response, etc. Since construction is a long-term continuous dynamic spatial–temporal progress, the face constantly advances during excavations. Thus, conditions surface surrounding areas are continuously revealed...

In contrast, precipitation reflect changes El Niño events. The ice-sheet melting may have offset Southern Oscillation variability at beginning Holocene. These simulations provide coherent framework refine...
