Fair 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 کاملThe Use of Millimeter Doppler Radar Echoes to Estimate Vertical Air Velocities in the Fair-Weather Convective Boundary Layer
Vertical velocity characteristics of the optically clear convective boundary layer (CBL) are examined by means of profiling airborne radar data collected in the central Great Plains during the International H2O Project, May–June 2002 (IHOP 2002). Clear-air echoes are sufficiently strong for the radar, a 95-GHz cloud radar, to detect most of the CBL at a resolution of 30 m. Vertical radar transe...
متن کاملFair space weather for solar cycle 24
[1] We discuss the polar field precursor method of solar activity forecasting, first developed 3 decades ago. Using this method the peak amplitude of the next solar cycle (24) is estimated at 124 ± 30 in terms of smoothed F10.7 Radio Flux and 80 ± 30 in terms of smoothed international or Zurich Sunspot number (Ri or Rz). This may be regarded as a ‘‘fair space weather’’ long term forecast. To su...
متن کاملFair-Weather Fans: The Correlation Between Attendance and Winning Percentage
In Rob Neyer's chapter on San Francisco in his Big Book of Baseball Lineups, he speculates that there aren't really good baseball cities, and that attendance more closely correlates with winning percentage than with any other factor. He also suggests that a statistically minded person look at this. I took the challenge and have been playing with a lot of data. This article is available at The C...
متن کاملFair 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 ...
