The Schumann resonance, a global electromagnetic phenomenon, is shown to be a sensitive measure of temperature fluctuations in the tropical atmosphere. The link between Schumann resonance and temperature is lightning flash rate, which increases nonlinearly with temperature in the interaction between deep convection and ice microphysics. 
Evidence on a link between the intensity of Schumann resonance and global surface temperature
A correlation is investigated between the intensity of the global electromagnetic oscillations (Schumann resonance) with the planetary surface temperature. The electromagnetic signal was monitored at
Evaluation of the linkage between Schumann Resonance peak frequency values and global and regional temperatures
Lightning-generated extremely low frequency electromagnetic energy (the Schumann Resonance) could be a sensitive indicator of tropical or global temperature. In this investigation, we analyze the
Spectral characteristics of Schumann resonances observed in central Europe
The vertical electric field component in the frequency range of Schumann resonances has regularly been measured at the Nagycenk Observatory in Hungary, in Central Europe since May 1993. The actual
Boundary Layer Quasi-Equilibrium Limits Convective Intensity Enhancement from the Diurnal Cycle in Surface Heating
AbstractA combination of cloud-permitting model (CPM) simulations, satellite, and reanalysis data are used to test whether the diurnal cycle in surface temperature has a significant impact on the i...
Lightning and climate: A review
Schumann resonance spectra in a two-scale-height Earth-ionosphere cavity
New expressions are developed for the amplitude and power spectra of the electric and magnetic components of lightning-excited Schumann resonances. A classical normal mode approach is used, yielding
Sprites, ELF Transients, and Positive Ground Strokes
In two summertime mesoscale convective systems (MCSs), mesospheric optical sprite phenomena were often coincident with both large-amplitude positive cloud-to-ground lightning and transient Schumann
Model variations of Schumann resonance based on Optical Transient Detector maps of global lightning activity
[1] We present model computations of global electromagnetic resonance (Schumann resonance) based on the monthly worldwide distribution of thunderstorm activity collected by the Optical Transient

The ionospheric potential (VI), a measure of the Earth's overall electric field intensity, correlates with the classic ‘Carnegie curve’ diurnal variation in electric field caused by the global
The tripole structure of thunderstorms
Evidence for the tripole structure of electrified clouds is summarized. The observed structure is quantitatively consistent with the results of laboratory simulations and suggests that collision
Global temperature variations between 1861 and 1984
Recent homogenized near-surface temperature data over the land and oceans of both hemispheres during the past 130 years are combined to produce the first comprehensive estimates of global mean
Simultaneous observations of Schumann resonances in California and Australia : evidence for intensity modulation by the local height of the D region
Observations are presented of the horizontal magnetic component of Schumann resonance intensities as simultaneously measured at locations in California and Western Australia during two separate
The Down Under Doppler and Electricity Experiment (DUNDEE): Overview and Preliminary Results
Abstract DUNDEE (Down Under Doppler and Electricity Experiment) is described. DUNDEE was carded out in the vicinity of Darwin, Northern Territory, Australia, during the wet seasons of November 1988
Schumann resonances and worldwide thunderstorm activity
Electric vertical and horizontal NS and EW components of natural ELF electromagnetic noises were observed through a year from February, 1967, to January, 1968. Mean diurnal variations of the Schumann
Low-frequency electromagnetic oscillations of the Earth-ionosphere cavity
The observational and theoretical work on the low-frequency electromagnetic oscillations of the earth-ionosphere cavity, known as the Schumann resonances, is reviewed. Additional theoretical
Large-scale charge separation in thunderclouds
Currently available evidence for the mechanisms thought to be responsible for large-scale charge separation in thunderclouds is reviewed. The evidence suggests that electrically charged precipitation
Annual and Seasonal Global Temperature Changes in the Troposphere and Low Stratosphere, 1960–85
Abstract Based on a 63-station radiosonde network, annual and annual temperature change have been estimated by means of linear regression for the earth’s surface, troposphere (1.5–9 km), tropopause
Diurnal power variations of the Earth‐ionosphere cavity modes and their relationship to worldwide thunderstorm activity
Measurements of ELF radio-noise power in the lowest modes of the earth-ionosphere cavity were taken throughout 12 days during February 1961. The mean diurnal variation of the power in the first mode
