Scientific community has been elaborating to better understand the observed climate and its variations, improve capability for predicting future climate. Many modeling groups participating in Coupled Model Inter-comparison Project (CMIP) have working towards multi-model ensemble approach that become a standard technique projecting assessing associated uncertainties deal with intrinsic shortcomings of models. Within this context, National Institute Meteorological Sciences/Korea Administration...
Abstract The National Institute of Environmental Research, under the Ministry Environment Korea, provides two-day forecasts, through AirKorea, concentration particulate matter with diameters ≤ 2.5 μm (PM ) in terms four grades (low, moderate, high, and very high) over 19 districts nationwide. Particulate are subjectively designated by human forecasters based on forecast results from Community Multiscale Air Quality (CMAQ) artificial intelligence (AI) models conjunction weather patterns. This...
Regional-scale projections of climate change signals due to increases in atmospheric CO2 are generated for the western United States using a regional model (RCM) nested within two global scenarios from GCM. The downscaled control improved local accuracy GCM results substantially. is reasonably close an 8-yr hindcast same RCM NCEP–NCAR reanalysis, despite wet biases high-elevation regions along Pacific coast. near-surface temperature signal ranges 3 5 K States. projected warming generally...
This study examines the potential impact of vegetation feedback on changes in diurnal temperature range (DTR) due to doubling atmospheric CO2 concentrations during summer over Northern Hemisphere using a global climate model equipped with dynamic model. Results show that induces significant increases daily mean and decreases DTR regardless presence effect. In feedback, increase productivity related warm humid lead (1) an greenness mid-latitude (2) greening expansion grasslands boreal forests...
Abstract Wind stilling has been observed in many regions across the Northern Hemisphere; however, related mechanisms are not well understood. Analyses of wind speed variations South Korea during 1993–2015 this study reveal that annual-mean surface speeds at rural stations have increased by up to 0.41 m s −1 decade , while those urban decreased −0.63 . The local found be negatively correlated with population density corresponding observation sites. Gustiness analyses show increase roughness...
Abstract Precipitation related to atmospheric rivers (ARs) is critical in shaping climate and extreme hydrologic events the mid‐latitude coastal regions, making it a recent topic of intense research. This study has analysed AR climatology, AR‐precipitation characteristics their regional variations East Asia (EA) for 1979–2015 using an inventory based on vertically‐integrated water‐vapour transport geometry. The frequency over EA varies seasonally with highest (lowest) summer (winter). peaks...
The framework for a simulation model which describes the dispersion of individual droplets water containing viable microbes is presented. accounts physical, chemical, biological, and measured meteorological parameters each droplet at many short time steps. Repeating modeling process will simulate cloud droplets. compared with Tulelake, Calif., release in 1988 found to show very similar patterns deposition within 30 m (the maximum observation distance source. A hypothesis survival sequence...
A number of indices have been employed to describe weather extremes on the basis climate regimes and public concerns. In this study, we combined these traditional into four groups according whether they relate warm (Twarm), cold (Tcold), wet (Pwet), or dry (Pdry) extremes. Analysis calculated for daily temperatures precipitation at 750 meteorological stations in Korea, China, Japan 1960s–2000s shows increasing trends Twarm Pdry events decreasing Tcold recent decades, particularly northern...
Abstract Surface air temperature, precipitation, and insolation over the conterminous United States region from North American Regional Climate Change Assessment Program (NARCCAP) regional climate model (RCM) hindcast study are evaluated using Jet Propulsion Laboratory (JPL) Model Evaluation System (RCMES). All RCMs reasonably simulate observed climatology of these variables. RCM skill varies more widely for magnitude spatial variability than pattern. The multimodel ensemble is among best...
ABSTRACT Uncertainty in calculating the spatial‐ and interannual variability of precipitation over India Tibet from widely used gridded datasets is examined for 29‐year period 1979 to 2007. defined terms spread among calculated multiple datasets, a useful method when similar or unknown accuracy are available analyses. The resulting uncertainty varies regions seasons. Geographical variations clearly seen signal‐to‐noise ratio ( SNR ), with largest Jammu Kashmir (J&K), western...
