Preliminary analysis of the zonal distribution of ENSO-related SSTA in three CMIP5 coupled models
The simulated sea surface temperature anomaly (SSTA) over the tropical Pacific during El Niño–Southern Oscillation (ENSO) is investigated in three representative coupled models: CESM1-CAM5, FGOALS-s2, and FGOALS-g2. It is found that there is a significant westward shift bias in reproducing the…

Comparison of Indian Ocean warming simulated by CMIP5 and CMIP6 models
Under the ongoing global warming, the sea surface temperature (SST) over the entire Indian Ocean (IO) has been warming saliently at a rate of 0.014°C yr−1 since the 1950s, which is larger than that in other regions of the globe. The salient IO warming reflects the synergistic effect of global…

Analysis of the characteristics of gravity waves during a local rainstorm event in Foshan, China
A detailed analysis of the dynamic frequency spectrum characteristics of gravity waves (GWs) during a local heavy rainfall event on 20–21 November 2016 in Foshan, China, is presented. The results of this analysis, which was based on high-precision microbarograph data, indicate that GWs played a key…

The global response of temperature to high-latitude vegetation greening in a two-dimensional energy balance model
The relationship between vegetation greening and climate change remains unclear due to its complexity, especially in drylands. Against the background of global warming, arid and semi-arid areas, including mid-latitude deserts, are most sensitive to climate change. In recent decades, the mechanisms…

Climate change trend and causes of tropical cyclones affecting the South China Sea during the past 50 years
Tropical cyclones (TCs) in the South China Sea (SCS) cause serious disasters and loss every year to the coastal and inland areas of southern China. The types of TCs are usually difficult to forecast, and studies on the understanding of the TCs affecting the SCS are lacking. In this study, the…

Contributions of climate change, land use change and CO2 to changes in the gross primary productivity of the Tibetan Plateau
The ecosystems on the Tibetan Plateau (TP) are highly vulnerable to climate change, rising CO2 concentration, and land-use and land-cover change (LULCC), but their contributions to changes in the gross primary productivity (GPP) of the TP are not clearly understood. In this study, the role of these…

Assessing the sensitivity of RegCM4 to cumulus and ocean surface schemes over the Southeast Asia domain of the coordinated regional climate downscaling experiment
Multi-year experiments are conducted using the most recent version of the Abdus Salam International Centre for Theoretical Physics regional climate model RegCM4 (version 4.7) to customize its performance over Southeast Asia — a region with few RCMs applied to date. The model is driven by…

Nocturnal-to-morning rains during the warm season in South China: characteristics and predictability
The characteristics of nocturnal-to-morning rainfall (NMR) during the warm season in South China are examined using hourly surface observations from 2015–2019. Results show that strong NMR is mainly located in coastal regions and mountainous areas. NMR mainly occurs during 0200–0800 LST. The…

Understanding long-term memory in global mean temperature: An attribution study based on model simulations
Long-term memory (LTM) in the climate system has been well recognized and applied in different research fields, but the origins of this property are still not clear. In this work, the authors contribute to this issue by studying model simulations under different scenarios. The global mean…
