Abstract The western North Pacific anticyclone (WNPAC) significantly influences the East Asian climate and is modulated by tropical sea surface temperature (SST). This study uses 142 AMIP simulations from 33 Coupled Model Intercomparison Project (CMIP6) models to quantify contributions of SST interannual variability WNPAC. forcing accounts for 66%, 77%, 49% WNPAC variance in winter, spring, summer, respectively. persistence depends on relaying effects three oceans. CMIP6 exhibit excessive...
Atmospheric dynamical and chemical models are conducted to explore impacts of urban land-use change on ozone concentrations over the Pearl River Delta (PRD) region, China. Two scenarios distributions used represent early 1990s current distributions. Urbanization increases 2-d averaged daytime (nighttime) temperature by 0.8°C (1.5 °C) reduces wind speed about 20% PRD areas. The boundary layer depth is up 400 m deeper, while there a 50-m increase during nighttime. combination these seemly...
Abstract A significant relationship exists between the Indian Ocean Dipole (IOD) and following year’s El Niño-Southern Oscillation (ENSO), in spite of uncertainty associated mechanisms. Here we show that spring sea surface temperature (SST) anomalies over southeastern (SEIO) play a bridging role teleconnection IOD subsequent ENSO. positive could induce tendency SST SEIO region from autumn to winter, primarily through cloud-radiation-SST feedback, forming an anomalous warming which persists...
Abstract Taking Typhoon Usagi (2013) as an example, this study used the Weather Research and Forecasting Model with Chemistry to investigate influence of anthropogenic aerosols on typhoons. Three simulations (CTL, CLEAN, EXTREME) were designed according emission intensity pollution. The results showed that although pollution did not demonstrate clear track strength typhoon, it clearly changed precipitation, distribution water hydrometeors, microphysical processes. In CLEAN experiment,...
Abstract This study investigated heavy frontal rainfall that occurred on 13–14 October 2011 over the Pearl River Delta (PRD) in China. The rainstorm was simulated using WRF-ARW Model (version 3.3), which included its urban canopy model. Although model-simulated convection 2 h early and second precipitation peak underestimated, model represented formation, development, extinction of captured distribution value. In addition, averaged value 49.7 W m −2 taken as anthropogenic heat flux (AHF)...
Substantial biomass burning (BB) activities in Indochina during March and April of each year generate aerosols that are transported via westerly winds to southern China. These BB have both radiative (direct semi-direct) indirect effects on the climate. This study evaluates impacts 2013 atmospheric conditions China using WRF-Chem sensitivity simulations. We show atmosphere becomes drier hotter under aerosol effect China, while changes linked opposite. The former (the latter) rises (reduces)...
Abstract This study used the Weather Research and Forecasting model with chemistry (WRF‐Chem) a parameterization for emissions of sea‐salt aerosols to assess effects on tropical cyclone. A control simulation (Ctl) emission flux that is one‐tenth in Ctl (Low) were conducted. Results show enhance condensation process, promoting vertical motion precipitation Peak value 120% Low. Enhanced results increase water vapor transport upper atmosphere, which promotes deposition growth cloud ice...
Abstract A record‐breaking rainfall event was initiated between the urban heat island (UHI) and a small trumpet‐shaped mountain (Huadu Mountain) to its north in Guangzhou City at midnight of May 6, 2017. Numerically simulating convection initiation (CI) challenging due insufficient model resolution inaccurate boundary layer parameterization, this study therefore examined pre‐convective mesoscale processes based on their four‐dimensional analyses obtained through data assimilation radar...
Abstract As one of the deep convection systems, tropical cyclones (TCs) could significantly affect thermodynamic structure and cloud microphysical processes near tropopause, which may cause changes in troposphere stratosphere water vapour activity, with important influences on global climate change. However, effects TCs tropopause lower remain unclear. Here, we use satellite data from year 2012 to 2016 assess effect at over Northwest Pacific Ocean. It is found that decrease temperature...
Abstract The recently developed maximum entropy production (MEP) model, an alternative parameterization of surface heat fluxes, is incorporated into the Weather Research and Forecasting (WRF) model. A pair WRF cloud‐resolving experiments (5 km grids) using bulk transfer model (WRF default) MEP fluxes are performed to hindcast October Madden‐Julian oscillation (MJO) event observed during 2011 Dynamics MJO (DYNAMO) field campaign. simulated latent sensible in runs general consistent with situ...
We investigate the effects of sea-salt aerosol (SSA) activated as cloud condensation nuclei on microphysical processes, precipitation, and thermodynamics a tropical cyclone (TC). The Weather Research Forecasting model coupled with Chemistry (WRF-Chem) was used together parameterization SSA production. Three simulations, different levels emission (CTL, LOW, HIGH), were conducted. simulation results show that contributes to processes autoconversion water accretion by rain, thereby promoting...
Abstract The effects of sea salt aerosols (SSA) on cloud microphysical processes, precipitation, and upper troposphere/lower stratosphere water vapour in tropical cyclones were studied with the Weather Research Forecasting Chemistry model. Two numerical experiments conducted: a control experiment (CTL) an emission intensity one-tenth that CTL (CLEAN). Results show increased SSA concentrations, production rates auto-conversion to form rain, accretion by rain experiment, leading increase...
