Brian Tinsley
Brian Tinsley is a physicist who for more than 60 years has been actively researching atmospheric and space physics. He has been a Professor of Physics at the University of Texas at Dallas since 1976 and has served many national and international scientific organizations. He obtained his PhD from the University of Canterbury in New Zealand in November, 1963, for research on optical emissions from the upper atmosphere. With his wife, Beatrice Tinsley, he came to Dallas to work at the newly formed Southwest Center for Advanced Studies, which became the University of Texas at Dallas in 1969. They divorced in 1978, their adopted children Alan and Theresa remaining with him.
During his time at the NSF in the late 1980s he began researching the effects of changes in the sun on weather and climate on the day-to-day, decadal and century timescale. He has been author of more than 40 papers on this topic. He has proposed a mechanism in which the link to the atmosphere is the solar wind that affects the downward ionosphere-earth current density in the global atmospheric electric circuit.
He formed the hypothesis that the Jz effects are due to electrical charge deposited on droplets and aerosol particles that significantly affect scavenging processes and the concentrations of the nuclei. The consequences of this include changes in cloud cover and rates of precipitation, and changes in surface pressure and atmospheric dynamics, as has been observed.
Dr. Tinsley and Dr. Burns of the Australian Antarctic Research Division and Dr. Zhou of the East China Normal University have shown that there are clear correlations between the electric current output of the internal atmospheric generators in the global electric circuit and surface pressure at both Antarctic and Arctic sites, fully consistent with the changes due to the solar wind. Thus the work has led to the discovery of an unexpected process in meteorology that has implications for climate. That is that the internal generation of atmospheric electricity, mostly in the tropical regions, affects clouds and meteorological processes all over the globe. Observations of cloud changes in polar regions and models of cloud charging and the effects of charge on cloud microphysics confirm these findings.
