The China Meteorological Administration (CMA)’s tropical cyclone (TC) database includes not only the best-track dataset but also TC-induced wind and precipitation data. This article summarizes characteristics key technical details of CMA TC database. In addition to data, other phenomena that occurred with TCs are recorded in dataset, such as subcenters, extratropical transitions, outer-range severe winds associated over South Sea, coastal landfalling China. These data provide additional...
Abstract This paper describes the access to, and content, characteristics, potential applications of tropical cyclone (TC) database that is maintained actively developed by China Meteorological Administration, with aim facilitating its use in scientific research operational services. records data relating to all TCs have passed through western North Pacific (WNP) South Sea (SCS) since 1949. TC collection has expanded over recent decades via continuous monitoring using remote sensing...
Abstract TRMM satellite 3B42 rainfall estimates for 133 landfalling tropical cyclones (TCs) over China during 2001–15 are used to examine the relationship between TC intensity and distribution. The rain rate of each is decomposed into axisymmetric asymmetric components. results reveal that, on average, closely related intensity. Stronger TCs have higher averaged peak rates, more total rain, larger areas, amplitudes rainfall, lower wavenumbers 1–4 relative rainfall. Among different change...
Abstract To evaluate the abilities of satellite retrievals in reflecting precipitation features related to tropical cyclones (TCs) affecting mainland China, four years 6- and 24-h from three datasets, namely Tropical Rainfall Measuring Mission algorithm 3B42, version 6 (3B42), Climate Prediction Center morphed (CMORPH) product, one based on Geostationary Meteorological Satellite-5 infrared brightness temperature (GMS5-TBB), are compared statistically with direct measurements surface gauge...
Abstract This article proposes a selective ensemble‐mean technique for tropical cyclone (TC) track forecast based on the errors of ensemble prediction system (EPS) members at short lead times (SLTs, 12 h in this study). The means (SEAV) and weighted (SEWE) selected EPS are applied to products from European Centre Medium‐range Weather Forecasts (ECMWF), Japan Meteorological Agency (JMA), National Centers Environmental Prediction (NCEP), China Administration 35 TCs western North Pacific 2010...
Thirty-year (1980–2009) tropical cyclone (TC) images from geostationary satellite (GOES, Meteosat, GMS, MTSAT and FY2) infrared sensors covering the Northwestern Pacific were used to build a TC size dataset based on objective models. The models are correlation between of TCs, defined as mean azimuth radius 34 kt surface winds (R34) brightness temperature radial profiles derived imagery. Using 2001 2009, we obtained 16,548 matchup samples found be positive in TC’s inner core region (in...
Characteristics of key parameters including the radius maximum wind and Holland-B parameter are investigated for historical typhoons in western North Pacific Ocean. The latest findings on drag coefficient summarized. relationship between moving speeds typhoon vortexes large-scale environmental steering flow is also using reanalysis data. A boundary layer model that considers height speed ratio vortex those at surface level (10 m) proposed. Then, a parametric field suitable Ocean...
Abstract Exposure correction is necessary for removing the distortion effects induced by nonstandard local exposure in raw near‐ground wind speed datasets. The accurate calculation of factor () speeds requires reliable input aerodynamic roughness length (). In this study, we evaluate performance an formula suggested World Meteorological Organization and estimation based on gustiness model. will be more reasonable if zero‐plane displacement considered under rough terrain conditions. An...

The numerical simulations are performed with a computational fluid dynamics (CFD) code using Reynolds‐averaged Navier–Stokes equations island off southeast coast China. A novel evaluation method which selects ERA‐5 reanalysis data as background to match CFD inlet is proposed validate performance simulated field. assessment results show...
Abstract Understanding wind characteristics of the tropical cyclone boundary layer (TCBL) over land is crucial for improving typhoon forecasts and designing wind‐resistant structures. This study employs a ground‐based Doppler radar (DWL) in Lujiazui, Shanghai, to examine evolution TCBL turbulence during Typhoon Muifa (2022), focusing on transition from periphery eyewall. Observations reveal significant changes characteristics, highlighting eye region's unique features complex dynamics...
Abstract How the complex urban surface heterogeneity influences wind field structures induced by tropical cyclones remains poorly understood despite its importance for disaster mitigation. Here high‐resolution numerical simulations using Weather Research and Forecasting model coupled with multi‐layer canopy (WRF/BEP, Building Effect Parameterization) are conducted to address this issue case of landfalling Typhoon Lekima (2019) over Yangtze River Delta (YRD) agglomeration. Results show that...
Abstract Landfalling tropical cyclones (TCs) often experience drastic changes in their motion, intensity, and structure due to complex multiscale interactions among atmospheric processes the coastal ocean, land, atmosphere. Because of lack comprehensive data low capability numerical models, understanding ability predict landfalling TCs are still limited. A 10-yr key research project on was initiated launched 2009 China. The has been jointly supported by China Ministry Science Technology,...
Abstract Typhoon Fitow made landfall south of Shanghai, China, on 6 October 2013. During the following two days, precipitation in excess 300 mm day−1 occurred 400 km to north typhoon center. The rain-producing systems included (i) outward-spiraling rainbands, which developed storm’s sector favorable environmental wind shear, and (ii) frontal cloud as a result coastal frontogenesis. Over rain area, addition enhanced ascent, there were increases low-level moisture, convective instability,...
