Plasmaspheric depletion and refilling associated with the September 25 , 1998 magnetic storm observed by ground magnetometers
The plasmaspheric mass density at was monitored by two IGPP/LANL ground magnetometer stations during the magnetic storm on September 25, 1998. Even at this low latitude the plasma density dropped significantly to of the pre-storm value. The total electron content (TEC) inferred by GPS signals also shows a sizable decrease during the storm. The observations suggest that the convection caused by ...
متن کاملCoastal Dynamics 2013 1277 DOES A MORE SOPHISTICATED STORM EROSION MODEL IMPROVE PROBABILISTIC EROSION ESTIMATES?
The dependency between the accuracy/uncertainty of storm erosion exceedance estimates obtained via a probabilistic model and the level of sophistication of the structural function (storm erosion model) embedded in the probabilistic model is assessed via the application of Callaghan et al.'s (2008) Joint Probability Model (JPM) at Narrabeen beach, Australia with three different structural functi...
متن کاملEffects of Wind Erosion and Soil Salinization on Dust Storm Emission in Western Iran
Dust storms are known as hazardous problems in western part of Iran. Iraq is one of the main sources for dust storm arriving to the western part of Iran. The Radial Basis Function Network model (RBFN) has been used to assess wind erosion hazards in the source area of dust storms over several western Iranian cities. Normalized Difference Salinity Index (NDSI) was used to determine the changes in...
متن کاملPlasmaspheric depletion and refilling associated with the September 25 , 1998 magnetic storm observed by ground magnetometers at L = 2
The plasmaspheric mass density at L ' 2 was monitored by two IGPP/LANL ground magnetometer stations during the magnetic storm on September 25, 1998. Even at this low latitude the plasma density dropped significantly to ' 1/4 of the pre-storm value. The total electron content (TEC) inferred by GPS signals also shows a sizable decrease during the storm. The observations suggest that the convectio...
متن کاملTwostream modeling of plasmaspheric refilling
Plasmaspheric refilling on an L = 4 flux tube was studied by using a time-dePendent, hydrodynamic plasmaspheric flow model in which the ion streams from the tWO hemispheres are treated as distinct fluids. In the model the continuity, momentum, and energy equations of a twoion (O + and H+), quasi-neu.tral, currentless plasma are solved along aclosed geomagnetic field line; diffusive quilibrium i...
