A possible relationship between Global Warming and Lightning Activity in India during the period 1998-2009 [PDF]

open access: yesarXiv, 2010
Lightning activity on a global scale has been studied season wise using satellite data for the period from 1998 to 2009. Lightning activity shows an increasing trend during the period of study which is highly correlated with atmospheric warming. A similar increasing trend of lightning activity is observed in the Indian region during the pre-monsoon ...

Lightning discharge identification system [PDF]

open access: yes, 1981
A system for differentiating between cloud to cloud and cloud to ground lightning discharges is described which includes an electric field antenna that senses the rate of charge of an electric field produced by a lightning discharge.

Hypoferremic Response to Chronic Inflammation Is Controlled via the Hemojuvelin/Hepcidin/Ferroportin Axis and Does Not Involve Hepcidin‐Independent Regulation of Fpn mRNA

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT The iron regulatory hormone hepcidin contributes to the pathogenesis of anemia of inflammation (AI) by inhibiting the iron exporter ferroportin in target cells, causing hypoferremia. Under acute inflammation, hepcidin induction requires hemojuvelin (Hjv), a bone morphogenetic protein co‐receptor, while Fpn mRNA is also suppressed in a hepcidin‐

Alternative photothermal/electrothermal hierarchical membrane for hypersaline water treatment

open access: yesSusMat, Volume 2, Issue 6, Page 679-688, December 2022., 2022
The structure of MDEM is constructed by vertically aligned micro/nano channels, and photo/electrothermal carbolong complexes (PCCs and ECCs). It can alternatively utilize electrical or light energy to generate heat, and the micro/nano channels within the membrane provide abundant channels for vapor escape, enhancing the desalination capacity. PCCs with

About Geometry and Initial Phase of Cloud-to-Ground Lightning [PDF]

open access: yesarXiv, 2016
Cloud-to-ground lightning is the most common among atmospheric discharges. Since electric fields in the vicinity of a thunder-cloud do not exceed 250 kV/m the physical process that triggers the lightning remains unexplained. [1, 2, 3] Recent measurements established a weak correlation between solar wind and incidence of lightning.

Characteristics of broadband lightning emissions associated with terrestrial gamma ray flashes [PDF]

open access: yes, 2011
To characterize lightning processes that produce terrestrial gamma ray flashes (TGFs), we have analyzed broadband (

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.

CAPE Times P Explains Lightning Over Land But Not the Land‐Ocean Contrast

open access: yesGeophysical Research Letters, 2018
The contemporaneous pointwise product of convective available potential energy (CAPE) and precipitation is shown to be a good proxy for lightning. In particular, the CAPE × P proxy for lightning faithfully replicates seasonal maps of lightning over the ...
