The global electrical circuit as global thermometer

AIP Conference Proceedings, 1992
Local observations in the tropics show that lightning activity increases strongly with the wet bulb potential, θw, of boundary layer air. The surface wet bulb temperature controls the vigor of convection and the accumulation of ice phase condensate in the mixed phase region of tropical convection, the apparent seat of lightning activity.

The Schumann Resonance: A Global Tropical Thermometer

Science, 1992
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.

The global circuit: Global thermometer, weather by‐product or climatic modulator?

Reviews of Geophysics, 1995
This paper will review progress on the fair weather global circuit and its coupling to the upper atmosphere. The paper will confine its focus to work done by scientists working in the United States of America during the last four years. The global circuit is an old and familiar topic thought by many to have been well understood many years ago.

The Carbon Dioxide Thermometer and the Cause of Global Warming

Energy & Environment, 1999
Carbon dioxide in the air may be increasing because the world is warming. This possibility, which contradicts the hypothesis of an enhanced greenhouse warming driven by man-made emissions, is here pursued in two ways. First, increments in carbon dioxide are treated as readings of a natural thermometer that tracks global and hemispheric temperature ...

Among Global Thermometers, Warming Still Wins Out

Science, 1998
GLOBAL CHANGERecent analyses show that the gap between the satellite temperature record and that of thermometers at the surface is more apparent than real. Although much was made of a 20-year-long satellite temperature record that showed a slight cooling, after considering the effects of El NiA±os and volcanoes and correcting for decay of the ...
