Mesoscale winds from the new ASCAT scatterometer

Introduction satellite based scatterometers provide high resolution all-weather wind vector fields over the seas. Wind speed and wind direction are provided at high accuracy under all weather conditions. The allweather EsA ERs scatterometer observations have proven its significant impact for the forecasting of fast developing and severe weather. Moreover, scatterometer wind fields are provided ...

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...
