Abstract The post-landfall decay of tropical cyclones (TC) is often closely linked to the magnitude damage environment, properties, and loss human lives. Despite growing interest in how climate change affects TC decay, data uncertainties still prevent a consensus on changes rates related precipitation. Here, after strict data-quality control, we show that rate TCs making landfall China has significantly slowed down by 45% from 1967 2018. We find that, except warmer sea surface temperature,...
Abstract The relationship between tropical cyclone (TC) rapid intensification (RI) and the distribution of inner‐core precipitation preceding RI is reexamined using satellite‐based measurements best‐track data. TCs experiencing (RITCs) are classified into weakly, moderately highly asymmetric categories according to 25th 75th percentiles an objective asymmetry index. Composite results indicate that weakly‐to‐moderately RITCs experience axisymmetrization before RI, resulting from increased...
Abstract The implication of outflow structure for tropical cyclone (TC) rapid intensification (RI) is investigated via a climatological study using the best track, reanalysis, and infrared brightness temperature data during 1980–2019. Composite analyses are performed in shear-relative framework RI events under different strengths environmental shear. Results show that moderate (4.5–11 m s −1 ) or strong (>11 shear onset follows significant increase upper-level upshear storm, which...
In this study, the monthly cycle of tropical cyclone (TC) rapid intensification (RI) ratio and its climate controlling factors are investigated. The TC RI is greatest in late fall season, although both total frequency samples largest peak summer season. environmental conditions examined to identify possible factors, including mean locations, ambient relative vorticity, vertical profiles atmospheric ocean temperatures. Consistent with previous studies, lower latitude location pronounced...
Abstract The rapid intensification (RI) of supertyphoon Lekima (2019) is investigated from the perspective balanced potential vorticity (PV) dynamics using a high-resolution numerical simulation. PV budget shows that inner-core anomalies (PVAs) formed during RI mainly comprise an eyewall tower generated by diabatic heating, high-PV bridge extending into eye resulting mixing, and upper-tropospheric core induced intrusion stratosphere. inversion total PVA at end captures about 90% changes in...
This study investigates the impacts of two different El Niño scenarios, east Pacific warming (EPW) and central (CPW), on tropical cyclone (TC) rapid intensification (RI) in western North (WNP). The ratio TCs with at least one RI occurrence (RITC) to all TC numbers (RITC ratio) shows monthly variations between groups. Higher RITC is found during July–October (November–December) for EPW (CPW) years. Further analyses indicate that difference attributed differences genesis locations, tracks...
Abstract This study investigates how the asymmetric inner‐core convection can modulate midlevel ventilation preceding rapid intensification (RI) of sheared tropical cyclones (TC) based on two numerical experiments Typhoon Lekima (2019) with warm (CTL) and relatively cool (SSTA0) sea surface temperatures (SSTs). The is dominated by an inflow layer between heights 5 10 km in upshear‐left quadrant, while convective development quadrant acts to induce outflow. These outflows, together reduced...
The tropical oceans spawn hundreds of disturbances during the cyclone (TC) peak season every year, but only a small fraction eventually develop into TCs. In this study, using observations from Global Precipitation Measurement (GPM) satellite, over western North Pacific (WNP) July to October 2014–2016 are categorized developing and nondeveloping groups investigate differences between satellite-retrieved convective stratiform precipitation properties in both inner-core (within 200 km...
This study investigates the potential impacts of multi-timescale atmospheric modes on tropical cyclone (TC) abrupt track turnings over western North Pacific during period 2000-2016. The composite large-scale environmental flow patterns sudden right-turning (SRT) and left-turning (SLT) TCs show that SRT process is generally accompanied by continuous deepening westerly trough, weakening eastward retreat subtropical high favoring strengthening asymmetric southwesterly around TC center, while...
Proper configuration of the physical parameterization scheme is important for accurate outcomes mesoscale weather forecasting model. This study evaluates performance four distinct cumulus schemes: Kain-Fritsch (KF), Grell 3D ensemble (GR3D), Modified Tiedtke (MTIEDKE) and (MKF) schemes, in simulating Tropical Cyclone Idai (2019) Southern Indian Ocean. Utilizing Weather Research Forecasting (WRF) model data from IBTrACS best track IMERG precipitation datasets, research assesses models'...
