Observation of an upward lightning flash with 21 upward positive leaders initiated from different wind turbines in wind farm

open access: yesHigh Voltage
As the wind turbine height increases, the probability of multiple upward leaders flashes within the wind farm increases. In this study, an upward lightning flash containing 21 upward positive leaders (UPLs) initiated from different wind turbines in ...

The start of lightning: Evidence of bidirectional lightning initiation

open access: yesScientific Reports, 2015
AbstractLightning flashes are known to initiate in regions of strong electric fields inside thunderstorms, between layers of positively and negatively charged precipitation particles. For that reason, lightning inception is typically hidden from sight of camera systems used in research.

A Review of Mechanical Reinforcement and Piezoresistive Self‐Sensing in Carbon Nanotube Fiber Composites

open access: yesPolymer Composites, EarlyView.
PSPP‐TRL mapping of CNT‐modified CFRP literature, with four recurring confusions resolved and five scale‐up problems quantified. ABSTRACT Carbon nanotube‐modified fiber composites are often presented as a route to stronger, tougher, and self‐sensing structural materials.

In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites

open access: yesJournal 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.

Understanding lightning leaders [PDF]

open access: yes, 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 ...

Characterization of synoptic environment for mesoscale convective systems over South Korea using ERA5 reanalysis data

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
In this study, the synoptic conditions for modes of mesoscale convective systems (MCSs) in South Korea are generalized based on composite analysis. The preferred precipitation region, synoptic patterns, moisture transport, sea surface temperature and thermodynamic and dynamic instabilities are characterized according to four modes: convective cells (CC)
