Attribution of extreme events is a challenging science and one that currently undergoing considerable evolution. In this paper are 19 analyses by 18 different research groups, often using quite methodologies, 12 occurred in 2012. addition to investigating the causes these events, multiple four high temperatures United States, record low levels Arctic sea ice, heavy rain northern Europe eastern Australia, provide an opportunity compare contrast strengths weaknesses various methodologies.

Abstract With the motivation to identify whether a reasonably simulated atmospheric circulation would necessarily lead successful reproduction of monsoon precipitation, performances five sets reanalysis data [NCEP–U.S. Department Energy (DOE) Atmospheric Model Intercomparison Project II (AMIP-II) (NCEP-2), 40-yr ECMWF Re-Analysis (ERA-40), Japanese 25-yr Reanalysis (JRA-25), Interim (ERA-Interim), and Modern-Era Retrospective Analysis for Research Applications (MERRA)] in reproducing...
Vegetation fires release a large fraction of light-absorbing components, which can contribute to the melting snowpack and alpine glaciers. However, relationship between variability in fire emissions glacier on Third Pole (TP) remains poorly understood. This study provides evidence that carbon from windward vegetation play crucial role comprehending TP, particularly during months intense March May for monsoon-dominated glaciers June October westerlies-dominated Furthermore, robust positive...
An overview of Chinese contribution to Coupled Model Intercomparison Project-Phase 5 (CMIP5) is presented. The performances five Climate/Earth System Models that participated in the CMIP5 project are assessed context climate mean states, seasonal cycle, intraseasonal oscillation, interannual variability, interdecadal global monsoon, Asian-Australian 20th-century historical simulation, change projection, and sensitivity. Both strengths weaknesses models evaluated. generally show reasonable...
The East Asian summer monsoon (EASM) experienced decadal transitions over the past few decades, and associated "wetter-South-drier-North" shifts in rainfall patterns China significantly affected social economic development China. Two viewpoints stand out to explain these shifts, regarding either a result of internal variability climate system or that external forcings (e.g. greenhouse gases (GHGs) anthropogenic aerosols). However, most models, for example, Atmospheric Model Intercomparison...
Abstract Salinity is a key ocean state property, changes in which reveal the variation of water cycle and thermohaline circulation. However, prior to this century, situ salinity observations were extremely sparse, decreased reliability simulations general circulation by climate models. In 2009, sea surface (SSS) covered global via European Space Agency's Soil Moisture Ocean (SMOS) mission, several versions SSS products subsequently released. How can these data benefit model performance?...
Abstract The large systematic biases in coupled models impact seasonal prediction results. With a motivation to reduce the influence of coupled‐model on predictions, singular value decomposition method was applied our study improve ability predict flood season precipitation. Based climate model, CAS‐ESM‐C, we conducted ensemble experiments from 1982 2018, with initial conditions provided by assimilation system. system integrated March August each year focus June precipitation China. results...
Abstract Over the past several decades, many efforts have been devoted to increasing simulation performance of climate models, but significant biases remain that hinder coupled systems. Hence, bias correction is regarded not only as a useful tool for improving simulations also an important step before data assimilation, which depends on hypothesis unbiasedness. In this study, using sea temperature climatological data, new ensemble‐based approach proposed correcting in CAS‐ESM‐C. Through...
The performances of CMIP5 atmospheric general circulation models (AGCMs) in simulating the western North Pacific subtropical high (WNPSH) El Niño decaying summers are examined this study. Results show that most can reproduce spatial pattern both climatological and anomalous associated with WNPSH summers. Most AGCMs capture westward shift compared location. With respect to sub-seasonal variation WNPSH, these reproducing northward jump better than eastward retreat from July August. Twenty-one...
Thermodynamic calculations have shown that chlorine can accumulate and cycle in the shaft of blast furnace form alkalis chlorides. Cycling upper part was simulated at laboratory scale with a countercurrent reduction (BORIS furnace) also directly investigated an industrial furnace. Experiments superposition two cycles: one “pure” large temperature domain, KCl narrower range (600-1,000°C). According to trials, effects on disintegration behaviour sinter are similar those alkalis.
In the ironmaking blast furnace, layers of coke, ferrous burden (sinter, pellets, lump ore) and additions are heated by an uprising gas flow. While descending, iron ore is reduced begins to melt. The liquid products slag hot metal trickle downwards into hearth, where they prevail as two immiscible phases filling voids within coke bed with floating on top metal. As hearth lined carbon blocks, which eroded passing flow, this region has a major impact campaign length furnace. furnace drained...
Abstract In this work, the first two leading modes of western Pacific subtropical high ( WPSH ) between early and late summer are compared. Results show that mode both June August is featured by an anomalous anticyclonic circulation in North region. The second (August) east–west (south–north) dipole over Pacific. Then, association El Niño‐Southern Oscillation ENSO examined. all PC1s connected with developing phase. connection June–July–August JJA PC2 decaying can only be seen July. August,...
With the motivation to improve simulation of East Asian summer monsoon (EASM) in coupled climate models, oceanic data assimilation (DA) was used CAS-ESM-C (Chinese Academy Sciences–Earth System Model–Climate Component) this study. Observed sea surface temperature assimilated into CAS-ESM-C. The climatology and interannual variability EASM simulated with DA were compared a traditional AMIP-type run. Results showed that climatological spatial pattern annual cycle precipitation western North...
A Chapman‐Kolmogorov equation describing compound transport of cosmic rays across the magnetic field, due to random walk field lines is investigated. The probability distribution (pdf) for particle P⊥, given as a convolution pdf PFRW, with Pp, relative walking field. model generalizes previous work Webb et al. [1], by including effects advection, drift and local perpendicular diffusion particles. At late times, it found that effective cross‐field coefficient κ⊥eff = κ⊥+κF where κ⊥...
By decomposing outgoing longwave radiation through empirical orthogonal function (EOF) analysis, the authors identify two anomalous convective systems in tropical western Pacific. Besides classical system near Philippines (PC), there is another Federated States of Micronesia (MC). As first EOF component this region, variance explained by MC higher than that PC. Both and PC are regulated sea surface temperature (SST) anomalies. While associated with an El Niño event, correlated SST anomalies...
This study examines the climatological sub‐seasonal evolution of western North Pacific subtropical high (WNPSH) in boreal summer using observation and multiple state‐of‐the‐art climate models, which has not been focused by previous research. The two shifts are analyzed, one from June to July (J–J) another August (J–A). In observation, WNPSH consistently retreats eastward jumps northward (weakens) August. Driven observed sea surface temperature (SST), multi‐models ensemble (MME) atmospheric...
