Fair weather atmospheric electricity: its origin and applications
Abstract—An entirely electrostatic view of the earth upper atmosphere system, as understood for example, by Lord Kelvin, underwent a paradigm shift around 1900 with definitive observations of sustained ion production in atmospheric air. Cosmic ray ionisation of atmospheric air, together with a potential difference between the upper atmosphere and the earth’s surface, yield vertical atmospheric ...
متن کاملSpace weather influences on atmospheric electricity
Atmospheric electricity is a venerable topic of geophysical science, dating back to the 1750s when Franklin and Dalibard established the presence of electricity in thunderstorms. Subsequently even fine conditions were observed to be electrified, and a downward vertical atmospheric electric field of magnitude ~100V/m observed near the surface during fair weather conditions. The origin of the “fa...
متن کاملThe influence of fair weather electricity on the charging of wind-dispersed pollen
Wind-pollinated plants reproduce by capturing pollen suspended in the air. Pollen grains are electrostatically charged and electric fields are present around plants due to the ambient fair weather electric field. A charged airborne particle in an electric field experiences an electrostatic force equal to the product of its charge and the electric field at its location. Consequently, electrostat...
متن کاملFair Pricing of Weather Derivatives
This paper proposes a consistent approach to the pricing of weather derivatives. Since weather derivatives are traded in an incomplete market setting, standard hedging based pricing methods cannot be applied. The growth optimal portfolio, which is interpreted as a world stock index, is used as a benchmark or numeraire such that all benchmarked derivative price processes are martingales. No meas...
متن کاملAll - Weather Hyperspectral Atmospheric Sounding
Remote measurements of Earth's atmospheric state using microwave and infrared wavelengths have been carried out for many years [1, 2]. Physical considerations involving the use of these spectral regions include the relatively high cloud-penetrating capability at microwave wavelengths and the relatively sharp weighting functions at infrared wavelengths, particularly in the shortwave region near ...
