In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites
Journal of Polymer Science, EarlyView.In situ curing‐enabled the 3D printing of continuous fiber/thermoset composites, which were reviewed. Particularly, four types of in situ curing, were discussed, including Radiation‐induced curing, photothermal curing, electrothermal curing, and frontal polymerization. AI‐integrated printing was also analyzed.

Lightning attachment to power transmission lines
, 2012 The effect of lightning channel inclination on the attachment of lightning flashes to UHV transmission lines is investigated using a lightning strike model that takes into account the competing connecting leaders issued from different conductors.

Impact of fragmented urbanization on observed precipitation
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study investigates the impact of fragmented urban landscapes on downwind precipitation by applying an innovative observation‐centered approach to an extensive rain gauge network in Belgium. The approach classifies the observations based on the upwind urban land cover fraction, and compares precipitation indices between rural‐ and urban‐labeled ...

Understanding lightning leaders [PDF]
, 2016 a lightning flash is defined by the initiation and multiple development of leaders. But lightning leaders are still poorly understood. Since most of my atmospheric electricity has been focused on lightning that means that it has been devoted to ...

Differences in M‐components between triggered lightning striking the ground and overhead line
High VoltageIn the summer of 2018–2019, rocket‐triggered lightning experiments were conducted in Guangzhou, China. There were two types of lightning targets: ground and overhead line.

Quarterly Journal of the Royal Meteorological Society, EarlyView.This paper describes the Met Office's new lightning location system LEELA. A brief overview of the upgraded hardware and geolocation algorithms is given. LEELA has improved lightning detection capabilities, especially at night. When comparing LEELA to the previous ATDnet system against ground truths LEELA has 100% storm detection efficiency within 5 km

Analysis of characteristics of lightning disaster and risk zoning in Ningbo Area(宁波地区雷电灾害特征分析及风险区划)
Zhejiang Daxue xuebao. Lixue ban, 2014 根据宁波地区ADTD闪电定位系统2010~2012年的地闪监测数据、雷灾资料以及2012年宁波地区人口及GDP数据，选取年平均地闪密度、单位面积雷灾频数、经济损失、人员伤亡、人员易损、经济易损6项指标，在详细分析宁波雷灾分布特征的基础上，采用主成分分析法对宁波各县地区雷灾易损性指标进行综合评价，并利用分层聚类分析法得出：政治经济文化中心的海曙区为雷灾极高易损区，经济发达的江东区以及工业基地镇海区为高易损区，江北区为中易损区，鄞州区、北仑区、象山县、宁海县、奉化市为低易损区，慈溪市和余姚市为极低易损区.

Object‐based deep learning for probabilistic convective‐core nowcasting from satellite data
Quarterly Journal of the Royal Meteorological Society, EarlyView.Convective cores detected from Meteosat infrared imagery are represented as compact physical objects to generate probabilistic nowcasts up to 6 h ahead. A spatio‐temporal transformer models interactions among evolving core populations and produces gridded probability forecasts across the western Sahel.
