Abstract Marine heatwaves (MHWs) are prolonged anomalous warm seawater events that can severely impact marine ecosystems and have never been studied previously in the South China Sea. Here, we combine satellite sea surface temperature reanalysis products to provide a systematic analysis of variations summer MHWs Sea potential influencing factors. The MHW days duration, calculated as multiyear average, mainly concentrated near Nansha Islands Beibu Gulf. Additionally, find significant...
Abstract Under the combined impacts of natural changes and human activities, past, current, future marine heatwaves (MHWs) in China's marginal seas adjacent offshore waters (CMSOW) need a comprehensive understanding. This study provides systematic analysis spatiotemporal variations using daily sea surface temperature data simulates trend 12 climate models. During 1982–2018, mean annual total days, duration, frequency, intensity MHWs CMSOW increased by 20–30 days/decade, 5–9 1–2 decade −1 ,...
The three large marine ecosystems (LMEs) bordering China (Yellow Sea/Bohai Sea, East and South Sea) have received excess nitrogen (N) phosphorus (P) in the past decades with detrimental consequences for ecosystem functioning, such as increased productivity, loss of biodiversity, proliferation harmful algal blooms (HABs). N loading much faster than that P. Here, we show HABs LMEs started to proliferate after N:P molar ratio exceeded threshold value 25 1980s. mismatch P inputs is not only...
The precipitation concentration index (PCI) is a powerful indicator for temporal distribution and also very useful the assessment of seasonal changes. primary objectives this study are to investigate analyse temporal–spatial variability patterns annual PCI values based on monthly data. These data were collected from 597 meteorological stations located throughout China, time period 1960–2016, used assess impacts geographical parameters (latitude, longitude, altitude) PCI. Additionally,...
Abstract Marine heatwave (MHW) characteristics, such as total days, average duration, and mean intensity, have increased in most global oceans. In contrast, marine cold‐spell (MCS) characteristics a decreasing trend over regions. However, the difference between MHW MCS present future climate is unclear. Here, we provide comparative assessment of these changes based on satellite sea surface temperature for 1982–2020 model projections 2021–2070. Globally, there are clear differences metrics....
Abstract An unprecedented marine heatwave (MHW) event occurred in the middle-high latitudes of western North Pacific during summer 2022. We demonstrate that excessive precipitation thousands kilometers away fuels this extreme MHW July In upper atmosphere, a persistent atmospheric blocking system, forming over region, reduces cloud cover and increases shortwave radiation at ocean surface, leading to high sea surface temperatures. Atmospheric perturbations induced by latent heat release from...
In marine gas turbines, variations in rotational speed occur all the time. To ensure adequate cooling effects on turbine blades, valves need to be adjusted change pressure upstream of pre-swirl nozzle. Changing such will have significant local or overall parameters, as core swirl ratio, temperature, flow rate coefficient, moment axial thrust etc. this paper, we studied characteristics within system a at low by varying The corresponding global Reynolds number ranged from Re = 2.3793 × 105...
Ediacaran assemblages immediately predate the Cambrian explosion of metazoans and should have played a crucial role in this radiation. Their wider relationships, however, remained refractory difficult to integrate with early metazoan phylogeny. Here, we describe frondlike fossil, Stromatoveris ( S. psygmoglena sp. nov.), from Lower Chengjiang Lagerstätte (Yunnan, China) that is strikingly similar vendobionts. The exquisite preservation reveals closely spaced branches, probably ciliated,...
Abstract Marine heatwaves (MHWs) are prevalent in the South China Sea (SCS) and primarily caused by anomalous western Pacific subtropical high (WPSH) which suppresses SCS summer monsoon. Our study investigates future MHWs response to enhanced WPSH. The results show that WPSH will be strengthened most models under highest emission scenario. Total days of significantly increase with enhancement peak at end 21st century. high‐value area total (>50 days) appears south‐central SCS. intensity...
Centrifugal pumps are widely used in various fields and have enormous energy-saving potential. In order to predict efficiency quickly accurately, firstly, by establishing a hydraulic loss model for centrifugal pump impellers, the functional relationship between impeller is constructed establish objective function. Secondly, calculate main dimensions of using velocity coefficient method function variables number blades Z outlet placement angle β2. And k0. Then, mathematical statistics, namely...
This article summarized the latest progress of a sub-project, Carbon Emission Cement Production in China, undertaken by Chinese Academy Sciences. project seeks to establish domestic CO2 emissions factor calculation system for China’s cement production. The Chinese-specific production will provide benchmark support international negotiation on climate change and baseline setting emission reduction target. Considering diversities different lines, sampling survey lines covering various...
Pressure fluctuation is an important factor affecting the stability of rotating machinery. Electric submersible pumps (ESPs) are generally arranged in a multistage series structure, and its internal unsteady flow extremely easy to propagate develop lengthy passage, which brings about differences characteristics pressure fluctuations each stage. In contrast conventional method processing signals, we propose parameter called “energy density (EFD)” pulsation by analogy with definition wave...
Abstract Lake heatwaves (LHWs) and cold‐spells (LCSs), similar to marine cold‐spells, can have long‐term impacts on lake ecosystems are vulnerable climate change. Here we first comparatively assess LHW LCS changes across the Qinghai‐Tibet Plateau (QTP) using satellite surface water temperature observations in 160 lakes over 1978–2017. Our findings reveal notable differences mean trends of metrics. Specifically, total days frequency been increasing at a rate 8.82 ± 1.25 per decade 0.78 0.10...
Internal tides profoundly influence diapycnal mixing and marine ecosystems in oceans worldwide. Previous estimates on internal focused regionally spanning a decade, leaving knowledge gap regarding their long-term global behavior, especially over centuries. Because of limited observations, critical question arises: How will warming affect tides? Using the Coupled Model Intercomparison Project Phase 6 (CMIP6) High-Resolution Empirical Tidal (HRET) model, we identify robust accelerating trend...
Abstract Marine heatwaves (MHWs) are extended periods of unusually warm ocean temperatures that significantly impact marine ecosystems. While most studies concentrate on temporal changes at a single point or spatial over fixed duration, the combined daily progression these in both space and time is still largely unexplored. Here, we employ observational data from three‐dimensional perspective (latitude × longitude time) to examine multidimensional characteristics Spatiotemporally Continuous...
