Summary: This study highlights the potential of decadal climate services and describes the development of four prototype climate service products in collaboration with users from agriculture, energy, infrastructure, and insurance sectors. However, to provide better services, more data and wider expertise are needed.

Summary: This study uses tide gauge records to show that decadal-scale coastal sea level variability increased dramatically in the second half of the twentieth century, with spatial coherence across different geographic locations. The increase was driven by changes in the amplitude, spatial pattern, and interbasin coherence of atmospheric pressure, wind, and sea surface temperature variability.

Summary: Recent observations show that the ocean has absorbed anthropogenic heat at an accelerated rate since the 1990s, with a nearly doubled uptake during 2010-2020 compared to 1990-2000. These heat uptake occurs mainly in global mode and intermediate water layers, spanning across both hemispheres and subtropical and subpolar mode waters. The warming of these water masses contributes to around 76% of global ocean warming after accounting for volumetric changes.

Summary: This study identifies the relationship between tropical southern Atlantic sea surface temperature anomaly and the El Nino-Southern Oscillation, and focuses on how the Pacific Decadal Oscillation modulates this relationship. The results show a significant but non-stationary interannual relationship, which undergoes a significant decadal shift. The study also proposes two processes to explain this decadal shift.

Summary: This study investigates the uncertainty, potential predictability, and drivers of decadal mean variables by decomposing the covariance matrix of multivariate decadal running means into fast and slow decadal variability. EOF analysis is then used to identify the dominant modes related to drivers of variabilities in sea surface temperature and geopotential height. The findings show that the Pacific decadal oscillation, radiative forcing, and Atlantic multidecadal oscillation are major drivers of decadal variability in sea surface temperature, while the northern annular mode and Atlantic multidecadal oscillation are associated with decadal variability in geopotential height.

Summary: This study reveals distinct decadal regimes in the impact of transbasin variability (TBV) on tropical cyclone frequency (TCF) over the Western North Pacific, Central-Eastern North Pacific, and North Atlantic basins. Changes in the interannual relationship between TBV and TCF are observed over different time periods, likely influenced by large-scale parameters. The interactions between ENSO and the Pacific decadal oscillation are believed to play a role in these observed decadal changes.

Summary: The distribution and interannual variation of the winter halocline in the upper layers of the World Ocean were found to be closely related to sea surface salinity, with strong haloclines occurring in areas of low salinity.

Summary: Arctic sea ice in summer experiences large-scale circulation anomalies on both interannual and decadal time scales. The interannual anomalies are mainly influenced by thermodynamic processes, while the decadal anomalies are driven by wind-induced sea ice drift. Both types of anomalies lead to sea ice decline, but the impact is more significant on the interannual time scale.

Summary: Monsoons have significant impacts on global population, affecting economy, agriculture, and human health. This study explores the ability of climate models to predict variations in summer monsoon precipitation. The multi-model ensemble-mean shows skill in predicting precipitation from one to 6-9 years ahead, with different levels of skill depending on the model, monsoon domain, and lead-time. The study identifies regions with better prediction performance and emphasizes the importance of simulating externally forced changes and Pacific Ocean temperatures for improved monsoon predictions.

Summary: The study analyzes the decadal and multidecadal variability in the ERSSTv5 global SST dataset, identifying multiple modes of variability in both fast and slow components. It is found that the slow modes are related to the Atlantic Multidecadal Oscillation (AMO) and sea surface temperature variability in the Indian Ocean gyre region.

Summary: This study focuses on the variation of the global mean sea level on interannual-decadal timescales and investigates the influences of climatic oscillations. Correlation analyses reveal high correlation between the global mean sea level and El Nino-Southern Oscillation, Pacific Decadal Oscillation, and Atlantic Multidecadal Oscillation, while weak or practically no correlation is found with Arctic Oscillation and Antarctic Oscillation.

Summary: This study investigates the thermal processes of cooling and re-equilibration in the forearc lithosphere and highlights the importance of specific geological background in determining the thermal conditions. The results reveal the influence of the evolution history of the forearc sequences and the characteristics of subduction systems on the cooling rates and closure temperatures of the forearc lithosphere.

Summary: This study investigates the spatial pattern of amplitude changes in tropical intraseasonal and interannual variability under global warming, focusing on precipitation and circulation. The moisture budget and thermodynamic energy equations are found to be simultaneously tenable, with the vertical gradient of mean-state moist static energy being a key factor in determining the spatial pattern of circulation changes. Vertical gradients of moisture and dry static energy are modified by global warming, influencing the moisture and thermodynamic energy balances and ultimately the spatial pattern of precipitation and circulation changes.
