Abstract The Third Pole (TP) is experiencing rapid warming and currently in its warmest period the past 2,000 years. This paper reviews latest development multidisciplinary TP research associated with this warming. facilitates intense broad glacier melt over most of TP, although some glaciers northwest are advancing. By heating atmosphere reducing snow/ice albedo, aerosols also contribute to melting. Glacier accompanied by lake expansion intensification water cycle TP. Precipitation has...
Abstract The increasing severity of droughts/floods and worsening air quality from aerosols in Asia monsoon regions are the two gravest threats facing over 60% world population living Asian regions. These dual have fueled a large body research last decade on roles impacting weather climate. This paper provides comprehensive review studies aerosols, monsoons, their interactions. region is primary source emissions diverse species both anthropogenic natural origins. distributions aerosol...
This work documents the first version of U.S. Department Energy (DOE) new Exascale Earth System Model (E3SMv1). We focus on standard resolution fully coupled physical model designed to address DOE mission-relevant water cycle questions. Its components include atmosphere and land (110-km grid spacing), ocean sea ice (60 km in midlatitudes 30 at equator poles), river transport (55 km) models. base configuration will also serve as a foundation for additional configurations exploring higher...
Abstract The process of parameter estimation targeting a chosen set observations is an essential aspect numerical modeling. This usually named tuning in the climate modeling community. In models, variety and complexity physical processes involved, their interplay through wide range spatial temporal scales, must be summarized series approximate submodels. Most submodels depend on uncertain parameters. Tuning consists adjusting values these parameters to bring solution as whole into line with...
There are two main uncertainties in determining future climate: the trajectories of emissions greenhouse gases and aerosols, response global climate system to any given set [ Meehl et al. , 2007]. These normally elucidated via application models, which provide information at relatively coarse spatial resolutions. Greater interest in, concern about, details change regional scales has provided motivation for introduces additional uncertainty Christensen 2007a]. fine‐scale responses, contrast...
The North American Regional Climate Change Assessment Program (NARCCAP) is an international effort designed to investigate the uncertainties in regional-scale projections of future climate and produce highresolution change scenarios using multiple regional models (RCMs) nested within atmosphere–ocean general circulation (AOGCMs) forced with Special Report on Emission Scenarios (SRES) A2 scenario, a common domain covering conterminous United States, northern Mexico, most Canada. program also...
ABSTRACT The Tibetan Plateau and its surroundings are known as the Third Pole (TP). This region is noted for high rates of glacier melt associated hydrological shifts that affect water supplies in Asia. Atmospheric pollutants contribute to climatic cryospheric changes through their effects on solar radiation albedos snow ice surfaces; moreover, behavior fates within cryosphere environmental impacts topics increasing concern. In this review, we introduce a coordinated monitoring research...
A 20‐year regional climate simulated by the Weather Research and Forecasting model has been analyzed to study influence of atmospheric rivers land surface conditions on heavy precipitation flooding in western U.S. The simulation realistically captured mean extreme precipitation, precipitation/temperature anomalies all river events between 1980–1999. Contrasting 1986 President Day 1997 New Year events, differences stability have an spatial distribution precipitation. Although both cases...
Abstract The Energy Exascale Earth System Model Atmosphere version 1, the atmospheric component of Department Energy's is described. model began as a fork well‐known Community Model, but it has evolved in new ways, and coding, performance, resolution, physical processes (primarily cloud aerosols formulations), testing development procedures now differ significantly. Vertical resolution was increased (from 30 to 72 layers), top extended 60 km (~0.1 hPa). A simple ozone photochemistry predicts...
Long‐term observational data reveal that both the frequency and amount of light rain have decreased in eastern China (EC) for 1956–2005 with high spatial coherency. This is different from trend total rainfall observed EC, which decreases northern EC increases southern EC. To examine cause trends, we analyzed long‐term variability atmospheric water vapor its correlation events. Results show very weak relationships between large‐scale moisture transport Because human activities, pollutant...

Abstract. The Atmospheric River Tracking Method Intercomparison Project (ARTMIP) is an international collaborative effort to understand and quantify the uncertainties in atmospheric river (AR) science based on detection algorithm alone. Currently, there are many AR identification tracking algorithms literature with a wide range of techniques conclusions. ARTMIP strives provide community information different methodologies guidance most appropriate for given question or region interest. All...

Abstract Aerosols have significant and complex impacts on regional climate in East Asia. Cloud‐aerosol‐precipitation interactions (CAPI) remain most challenging studies. The quantitative understanding of CAPI requires good knowledge aerosols, ranging from their formation, composition, transport, radiative, hygroscopic, microphysical properties. A comprehensive review is presented here centered the based chiefly, but not limited to, publications special section named EAST‐AIRcpc concerning...
Aerosol indirect effects have remained the largest uncertainty in estimates of radiative forcing past and future climate change. Observational constraints on cloud lifetime are particularly challenging since it is difficult to separate aerosol from meteorological influences. Here we use three global models, including a multi‐scale aerosol‐climate model PNNL‐MMF, show that dependence probability precipitation loading, termed frequency susceptibility ( S pop ), good measure liquid water path...
