Rogue wave early warning through spectral measurements?

Article history: Received 7 December 2010 Accepted 10 December 2010 Available online 17 December 2010 Communicated by V.M. Agranovich We study the spectra of the Peregrine soliton and higher-order rational solutions of the nonlinear Schrödinger equation (NLSE), which we use as a model of the rogue waves in optics and in the deep ocean. We show that these solutions have specific triangular spect...

3.6 Space Weather Effects on Soho and Its Leading Role in the Early-warning System for Space Weather

Since its launch on 2 December 1995, the Solar and Heliospheric Observatory (SOHO) has provided an unparalleled breadth and depth of information about the Sun, from its interior, through the hot and dynamic atmosphere, and out to the solar wind. In addition SOHO has several times demonstrated its leading role in the early-warning system for space weather. SOHO is in a halo orbit around the L1 L...

Commercial GPS in the Stratosphere: Cell Phone GPS Receiver Performance on a High Altitude Weather Balloon

The primary objective of this effort was to characterize the GPS performance of a smartphone at high altitudes. Due to International Traffic in Arms Regulations (ITAR) restrictions in the United States, very little GPS data above 60,000 ft (18.3 km) is openly available. Tethered to a high altitude weather balloon, a Google Nexus S cell phone was taken to high altitudes while logging GPS data. I...

Implementing a Weather-Based Early Warning System to Prevent Traffic Accidents Fatalities

Introduction: The present study aims to design a weather-based early warning system to prevent traffic accidents fatalities. Methodology: In this study, the Early Aberration Reporting System (EARS) was used to determine epidemic threshold. By roc curve, the Sensitivity and Specificity of temperature points were determined and, the point with highest sensitivity and specificity was selected base...
