Abstract The activity of the summer monsoon generates a complex convective environment and results in large amount convection initiation, whether embedded or isolated (i.e., ECI ICI). However, there is still no consensus on how different are triggering conditions that they undergo. For first time, respective spatiotemporal distributions ICI, as well their dependence environments, lifting conditions, connection to circulations, investigated statistically by using observations from radar...
We propose an atom-assisted cavity optomechanical system consisting of a single $\mathrm{\ensuremath{\Lambda}}$-type three-level atom, mechanical resonator, and sideband-driven cavity. The analytic expression the system's evolution is constructed under consideration fields, then steady-state solution electromagnetically optomechanically induced transparency amplification presented. In resolved red sideband case, we demonstrate appearance when two sets two-photon resonances are satisfied....
Abstract A mesoscale convective system (MCS) was initiated on the lee side of Wuling Mountain in central‐east China late afternoon (1700 LT) June 27, 2016, and led to an early morning precipitation peak. We investigated initiation (CI) mechanism this MCS using radars automatic weather station observations, WRF model simulation, analysis from radar data assimilation Variational Doppler Radar Analysis System. It found that convection elevated as indicated by convergence zone updraft located...
This paper finds that Chinese manufacturing firms engage in outward foreign direct investment (ODI) have better economic performance than non-ODI firms. Overall, ODI are more productive and higher profitability The sector analysis shows the exceptional is significant for labor-intensive industries. Finally, activity can raise productivity of other an industry. larger within industry, all suggests domestic set up their firm's global strategy reallocate resources according to changing...
Abstract Convection is the main contributor to heavy rainfall over China's Yangtze‐Huai River Basin (YHRB) during Meiyu season; however, mechanisms of convection initiation (CI) associated with front are still not well understood. In this study, a large set 86,099 CI events, identified from composite reflectivity data in YHRB six seasons, were used investigate characteristics spatiotemporal distribution YHRB. The result showed that overwhelming majority events (∼90%) occurred region existing...
An hourly rainfall of 201.9 mm fell in Zhengzhou on 20 July 2021, breaking the record mainland China and causing severe urban flooding human casualties. This observation-based study investigates associated convective-scale mesoscale dynamics microphysical processes using disdrometer polarimetric radar observations aided by retrievals from Variational Doppler Radar Analysis System. The synoptic flow forcing brought abundant moisture oceans converged at Zhengzhou; then, extreme was produced a...
Abstract We investigated coastal low‐level jets (CLLJs) over Beibu Gulf, China, during the warm season (May to July) using hourly model simulations from a mesoscale weather research and forecasting with 9‐km horizontal resolution. Two high‐incidence CLLJ areas were identified Gulf: one located on leeward side of Annamite Range that prevailed after sunset second off northwestern coast Hainan Island reached its maximum intensity at midnight. The upstream wind was too weak pass range daytime...
Abstract. Downhill thunderstorms frequently occur in Beijing during the rainy seasons, leading to substantial precipitation. The accurate intensity prediction of these events remains a challenge, partly attributed insufficient observational studies that unveil thermodynamic and dynamic structures along vertical direction. This study provides comprehensive methodology for identifying both enhanced dissipated downhill thunderstorms. In addition, radar wind profiler (RWP) mesonet has been built...
Abstract. The planetary boundary layer (PBL) over the Tibetan Plateau (TP) exerts a significant influence on regional and global climate, while its vertical structures of turbulence evolution features remain poorly understood, largely due to scarcity observations. This study examines profile daytime variation in dissipation rate (ε) PBL free troposphere TP using high-resolution (6 min 120 m) measurements from radar wind profiler (RWP) network, combined with hourly data ERA5 during period 1...
Abstract Low‐level Jets (LLJs) play a critical role in triggering nocturnal rainfall many areas on our planet. Nevertheless, little is known regarding the vertically resolved evolution of LLJs preceding rainfall. Here, high‐resolution wind measurements from radar profiler network Beijing are used to monitor continuous boundary‐layer jets (BLJs) and synoptic‐system‐related (SLLJs) before under southwesterlies synoptic pattern for summers 2020–2023. The results show that inertial oscillations...
ABSTRACT Aim Renal thrombotic microangiopathy (TMA) is a common pathological manifestation of Castleman's disease (CD)‐associated renal lesions. Increased level plasma vascular endothelial growth factor (VEGF) has been shown in single‐case reports. We aimed to investigate the dysregulation VEGF pathogenesis CD‐associated TMA‐like lesions (CD‐TMA) larger cohort. Methods Nineteen patients with clinico‐pathologically diagnosed CD involvement were enrolled. Ten pregnancy TMA or unknown reasons...
Abstract We investigate coastal low‐level jets (CLLJs) in the early warm season during 2006–2011 over Bohai Sea using a 9‐km horizontal resolution output data from Weather Research and Forecasting model. CLLJs mainly occur May when large‐scale low is located land to north Pacific high southeast of study area. The occurrence exhibits an obvious diurnal cycle with two different peaks: one at night, central region, other afternoon, northern region mountains both eastern western sides. A...
This article finds that the overall effect of foreign direct investment (FDI) and thereby China–US bilateral treaties (BIT) on Chinese manufacturing sector is positive, which raises productivity profitability firms, using various econometric models other evidence. The as a whole has already opened up to world economy needs continue this process. industries in do not need be protected, except for limited fields related national security, scarce natural resources well-defined strategic...
Warm zone rainstorms and frontal are two types of that often occur in the rainy season Jiangxi (located eastern part China). The ability to correctly identify type is important for accurate forecasting rainstorms. Two heavy took place province. first rainstorm occurred from 20:00 BJT (Beijing Time) on 6 June 9 (referred as “6.9” process) another 21 22 process), 2019. We analyzed rainstorms’ processes by using ground-based observation data, NCEP/FNL reanalysis ECMWF CMA-SH9 numerical...

Water vapor transport is an important foundation and prerequisite for the occurrence of rainstorms. Consequently, understanding water as well sources during rainstorm processes should be considered essential to study formation mechanism In this study, Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model adopted backward tracking trajectories “7·20” extraordinary heavy rain process in Zhengzhou City China that occurred on 20 July 2021. On basis, trajectory clustering method...
The 2020 Meiyu season has received extensive attention due to its record-breaking rainfall in the Yangtze–River Huai Basin (YHRB) region of China. Although features have been well studied on various time scales, sub-hourly/hourly are unknown. In this study, a wavelet analysis was applied 1 min data from 480 national rain gauges across YHRB, and hourly synoptic patterns during were grouped using an obliquely rotated principal component T-mode (PCT). results suggest that variances sub-hourly...
