Saturn’s equinoctial auroras
[1] We present the first images of Saturn’s conjugate equinoctial auroras, obtained in early 2009 using the Hubble Space Telescope. We show that the radius of the northern auroral oval is 1.5 smaller than the southern, indicating that Saturn’s polar ionospheric magnetic field, measured for the first time in the ionosphere, is 17% larger in the north than the south. Despite this, the total emitt...
متن کاملEquinoctial transitions in the ionosphere and thermosphere
Equinoctial summer/winter transitions in the parameters of the F2-region are analyzed using ground-based ionosonde and incoherent scatter observations. Average transition from one type of diurnal NmF2 variation to another takes 20–25 days, but cases of very fast (6–10 days) transitions are observed as well. Strong day-time NmF2 deviations of both signs from the monthly median, not related to ge...
متن کاملHigh-Accuracy Orbital Dynamics Simulation through Keplerian and Equinoctial Parameters
In the last few years a Modelica library for spacecraft modelling and simulation has been developed, on the basis of the Modelica Multibody Library. The aim of this paper is to demonstrate improvements in terms of simulation accuracy and efficiency which can be obtained by using Keplerian or Equinoctial parameters instead of Cartesian coordinates as state variables in the spacecraft model. The ...
متن کاملSevere Local Storms
Knowledge of severe local storms has been increasing rapidly in recent years as a result of both observational studies and numerical modeling experiments. This paper reviews that knowledge as it relates to development of new applications for forecasting of severe local storms. Many of these new applications are based on physical understanding of processes taking place on the storm scale and thu...
متن کاملDust Storms: Schwartz's Response
Coarse Particles and Dust Storm Mortality In a paper titled "Episodes of High Coarse Partide Concentrations Are Not Associated with Increased Mortality," Schwartz et al. (1) concluded that "coarse particles from windblown dust are not associated with mortality risk." The authors seem to have overlooked the medical literature on the health effects of the historic U.S. dust storms of the dust bow...
