[1] The 15-month climatology of medium-scale traveling ionospheric disturbances (MSTIDs) during a solar minimum period has been constructed from observations dense GPS receiver array in Central China. In total, 793 MSTID events are identified, with peaks occurrence at 1500 LT and 0100 LT. MSTIDs decreases following an increase geomagnetic activity, 46% the MSTIDS occurring daytime. Daytime characterized by major maximum around winter solstice equatorward propagation direction. period, phase...
The longest total solar eclipse of this century occurred in East and South Asia on 22 July 2009. was accompanied with a medium magnetic storm, whose main phase onset ∼27 min after the passage Moon's umbral shadow. Using TEC data from 60 GPS stations, we construct differential maps to investigate ionosphere response central China range 26°N–36°N, 108°E–118°E (i.e., latitude 15°N–25°N). During eclipse's totality, “shadow” shown as depletion area formed ∼100 km south path maximum decrease 5...
Abstract Atmospheric profiles of temperature ( T ), vapor density ρ v and relative humidity (RH) retrieved from ground‐based microwave radiometer (MWR) measurements are compared with radiosonde soundings at Wuhan, China. The MWR retrievals were averaged in the ±30 min period centered sounding times 00 12 UTC. A total 403 760 under clear cloudy skies selected. Based on comparisons, have better consistency than RH profiles, lower levels upper levels, clear‐sky profiles. Three cloud types (low,...
SnO 2 @carbon (SnO @C) nanofibers (NFs) have been prepared by electrospinning method and evaluated as anodes in lithium‐ion battery half cells. XRD were carried out to provide further information about the structure of as‐prepared NFs, all peaks can be readily indexed rutile phase (JCPDS No. 41–1445). Electrochemical characterization galvanostatic charge‐discharge tests shows that NF first discharge capacities 1375.5 mA h g −1 at 80 current density. This excellent Li‐ion storage capability...
Sixty-eight genera and 164 species in the Changxingian Stage 12 20 lower Griesbachian are recorded on basis of brachiopod fossils collected from 32 sections South China review Chinese literature.Of these, 24 34 described here, including three new (Fanichonetes, Prelissorhynchia, Rectambitus) (Acosarina strophiria, Enteletes asymmatrosis, Peltichia schizoloides, Derbyia pannuciella, Perigeyerella altilosina, Chonetinella cursothonia, C. volitanliopsis,
On 12 May 2008 at 06:28 UT a major earthquake of magnitude 8.0 struck Wenchuan County (31.0° N, 103.4° E) in southwest China. Ionospheric total electron content (TEC) values, derived from network 58 global positioning system (GPS) receivers over China and nearby countries, were used to investigate the ionospheric precursor great earthquake. The observations revealed that there was an anomalous enhancement TEC (100% increase on 15-day median) during afternoon–evening sector 9 while...
Abstract With analysis of local climate zone (LCZ) classification, approximately 52.0% underlying surfaces in Beijing are covered by buildings with LCZ 5 (open midrise) accounting for the highest proportion, and D (low plants) is most distributed among natural surface types. Compared to surfaces, building have higher values high temperature (HT) heat wave (HW) days, HW intensity, maximum duration. In recent decades, HT days on start earlier end later than those surfaces. Building make...
To reduce the experimental costs associated with tool condition monitoring (TCM) under new cutting conditions, a finite element modeling (FEM)-assisted deep subdomain adaptive network (DSAN) approach is proposed. Initially, an FEM technique employed to construct model for (target domain), and similarity between simulated data assessed obtain valid samples target domain. Subsequently, time–frequency Markov representation method utilized extract imaging features from samples, which serve as...
In this paper, electron densities during 25–28 September 2000 observed by the Millstone Hill incoherent scatter radar (ISR) are assimilated into a one‐dimensional midlatitude ionospheric theoretical model using an ensemble Kalman filter (EnKF) technique. It is found that (1) derived vertical correlation coefficients of density show obvious altitude dependence. These variations consistent with those from ISR observations. (2) The EnKF technique has better performance than 3DVAR especially in...
Abstract We investigated the cloud liquid water (CLW) and rain (RLW) during weak precipitations (rain rate below 12 mm/h) using microwave radiometer microrain radar measurements collected by Integrative Monsoon Frontal Rainfall Experiment over central China in 2018. The CLW path increased sharply from 0.6 to 4.1 mm for precipitation clouds. RLW presented a similar trend, although it had larger correlation coefficient with rate. Precipitation efficiency reached up ~50% then clearly decreased...
The longest total solar eclipse during the 21st century with a maximum duration of 6 min and 39 s occurred in South East Asia on 22 July 2009. TEC data from four GPS stations region (around 30°N) 105°E to 135°E are used study variation TEC. Height profiles electron density Formosa3/Cosmic satellites height dependence response. We also modeled effects ionosphere by an ionospheric model. Both observations F3/C results show that there is overall decrease below F2 region, largest relative...
The precursory processes detected from unambiguous and repeatable instrumental observations that precede an earthquake remain elusive despite the multiple types of pre-earthquake signals gained geo-electricity, geomagnetism, electromagnetism.Recently, much attention has been paid to associate abnormal behaviors TEC (total electron content) in ionosphere, with seismic forcing.In this paper, we examined ionospheric variations 1 -2 weeks preceding 20 moderate great earthquakes (M = 5 -8)...
Abstract Southwest China is with complex topography including basins, mountains, hills and plains, where abrupt heavy rainfall events (AHREs) occur frequently are difficult to quantitatively estimate due limited ground‐based observations. Using the data of ground rain gauges GPM dual‐frequency precipitation radar during April September in 2014–2020, this study investigates vertical structures AHREs over southwest China. Both mass‐weighted mean diameter ( D m ) reflectivity Z e increase...
Hubei Province Region (HPR), located in Central China, is a concentrated area of severe convective weather. Three processes occurred HPR were selected, namely 14–15 May 2015 (Case 1), 6–7 July 2013 2), and 11–12 September 2014 3). In order to investigate the differences between three cases, temporal spatial distribution characteristics cloud–ground lightning (CG) flashes precipitation, radar parameters, evolution cloud environment (including water vapor (VD), liquid content (LWC), relative...
Heat wave is serious natural disaster that can harm human health and affect social economy, transportation ecological environment. This paper investigates the long term trends of high temperature events in three major cities (Beijing, Tianjin Shijiazhuang) northern China during 1970–2019, quantifies contributions main influencing factors to variability days. High Beijing–Tianjin–Shijiazhuang mainly occur from June July account for 60–65% annual total, showing a significant upward trend...
