CHINOOK WINDS

Weather, Chinook, and stroke occurrence.

BACKGROUND Changes in weather and season have been linked to stroke occurrence. However, the association has been inconsistent across stroke types. Calgary is a city in the Chinook belt and is subject to high variability in weather conditions. METHODS We obtained hourly weather data over a 5-year period from 1996 to 2000; Chinook events were identified according to the accepted definition. We...

Parker Winds Revisited: An Extension to Disk Winds

Parker Winds Revisited: An Extension to Disk Winds by Timothy R. Waters Dr. Daniel Proga, Examination Committe Chair Associate Professor of Physics & Astronomy University of Nevada, Las Vegas A simple 1D dynamical model of thermally driven disk winds is proposed, based on the results of recent, 2.5D axi-symmetric simulations. Our formulation of the disk wind problem is in the spirit of the orig...

Improvement of vertical winds

Protoneutron Star Winds

Neutrino-driven winds are thought to accompany the Kelvin-Helmholtz cooling phase of nascent protoneutron stars in the first seconds after a core-collapse supernova. These outflows are a likely candidate as the astrophysical site for rapid neutron-capture nucleosynthesis (the rprocess). In this chapter we review the physics of protoneutron star winds and assess their potential as a site for the...

Reconnection in pulsar winds

The spin-down power of a pulsar is thought to be carried away in an MHD wind in which, at least close to the star, the energy transport is dominated by Poynting flux. The pulsar drives a low-frequency wave in this wind, consisting of stripes of toroidal magnetic field of alternating polarity, propagating in a region around the equatorial plane. The current implied by this configuration falls of...
