Abstract Diurnal and seasonal variation, intensity, structure of deep convective systems (DCSs; with 20-dBZ echo tops exceeding 14 km) over the Tibetan Plateau–South Asian monsoon region from Plateau (TP) to ocean are investigated using yr Tropical Rainfall Measuring Mission (TRMM) data. Four unique regions characterized by different orography selected for comparison, including TP, southern Himalayan front (SHF), South subcontinent (SAS), ocean. DCSs intense (IDCSs; 40-dBZ 10 occur more...
Intrinsically stretchable conductors play key roles in the dynamic interfacing of electronic devices with soft human tissues. However, it is difficult to simultaneously achieve high electrical conductivity and mechanical stretchability. Here, highly conductive thin film electrodes are prepared by combining PEDOT:PSS a mutually plasticized polymer dopant. Notably, harsh acid treatment for enhancement avoided, good solvent tolerance optical transparency realized, all which essential device...
Lightning flash activities on the Tibetan Plateau are investigated using observations from lightning imaging sensor. About 95% of flashes found to occur during May September with a single peak in summer June August. There is substantial activity plateau, especially southern and eastern plateau. The diurnal variation shows prominent 1500 1700 LT for most plateau earlier delay western, northern, central Few observed between 0000 1000 LT. highest density grassland value 4.5 km −2 yr −1 , while...
The data from the lightning imaging sensor (LIS), precipitation radar (PR), and passive microwave (TMI) onboard Tropical Rainfall Measuring Mission (TRMM) satellite 1998 to 2005 have been used investigate activity characteristics before after onset of South China Sea (SCS) summer monsoon. results show that over SCS begin enhance in April, peak May, decrease June. Compared premonsoon season, mean cell‐level flash rate decreased 13% optical radiance increased 15% during monsoon respectively....
Abstract Based on 16 years of Tropical Rainfall Measuring Mission (TRMM) data and NCEP Climate Forecast System Reanalysis data, the most intense convective systems (ICSs) along southern Himalayan front (SHF) are studied using multivariate techniques principal component analysis in T mode k-means cluster analysis. Three clusters, classified according to near-surface fields wind, specific humidity, available potential energy, inhibition, correspond premonsoon (March–May), establishment monsoon...
Long-term epidermal recording of bioelectricity is paramount importance for personal health monitoring. It requires stretchable and dry film electrodes that can be seamlessly integrated with skin. The simultaneous achievement high conductivity skin-like ductility conducting materials a prerequisite reliable signal transduction at the dynamic interface, which also bottleneck electrophysiology. Here, carbon nanotubes (CNTs) are introduced as "conjugation linkers" into topologically plasticized...
Characteristics of induced voltage in a horizontal conductor due to natural lightning with 9 dart leader/return stroke sequence were analyzed. Effect various parameters on the was examined by numerical simulation. The varied from minimum 4.6 kV maximum 18.6 geometric mean 11.2 kV. half-peak width and down time 0.87 2.9 μs, respectively. simulated results showed that both ends would increase increasing return velocity also height conductor. matched grounding impedances but relationship...
Abstract Global flash activity shows great contrast in different regions. Temperature and humidity are the essential meteorological factors that result this difference. The regional response of lightning activities to relative ( R H ) is examined at longitudes latitudes using data based on satellite NCEP metrological observations (from 1995 2002). indicates respond positively within longitudinal belts where more than 74% negatively for region less 72%. A similar found latitudinal belts. It...
Abstract The properties of stratiform and the convective precipitation tropical cyclones (TCs) over northwest Pacific are examined using Tropical Rainfall Measuring Mission data for 1998–2013. TCs classified into inner core (IC), rainband (IB), outer (OB) regions, results show that dominated by precipitation, which accounts more than 78% total raining area. highest fraction area exists in IB region increases as TC intensity (from 80% to 93%). Strong signatures generally occur IC region, less...
Abstract Lightning activity changes greatly on temporal and spatial scales. The data from Imaging Sensor, boarded the Tropical Rainfall Measurement Mission (TRMM) Satellite, are used to study lightning activities in several typical regions of world. It is found that great differences exist different for flash frequency intensity. oceans tens hundred times smaller than continents. number difference caused by not only days but also an individual thunderstorm a region. discharge intensity shows...
Abstract We study the spatial and temporal distribution of lightning flash activity its response to thermodynamic characteristics on Tibetan plateau by using composite gridded data from 1995 2002 observed satellite‐based sensors, provided NASA LIS/OTD Science Team in Marshall Space Flight Center. The result shows that mean density was 3 fl·a −1 ·km −2 , maximum central Plateau around (32°N, 88°E) with a peak value 5.1 . exhibited seasonal variation mainly occurred June August period late...
Abstract. Based on the 16-years Tropical Rainfall Measuring Mission (TRMM) satellite observational data, convective characteristics of thunderstorms over different topographic regions, as well their radar echo structural and lightning activity, are analyzed. The results reveal that Tibetan Plateau have weak frequency small horizontal scale, but occurrence is largest, accounting for ~ 20 % total precipitation events, followed by 10 adjacent foothills to east hilly land in southern China, with...
