We investigated the electrostatic charging behavior of submillimeter-sized dust particles located in Saturn's magnetosphere. The charging effects we considered included electron/ion capture from the magnetospheric plasma, electron/ion capture from the solar-wind plasma, the photoelectric effect from solar radiation, and secondary electron emission from energetic electrons. In our results, we sh...

introduction one of the factors that affect the climate of arid and semi-arid areas is dust storm. numerical models are new methods for evaluation of dust storms which can also be used for forecasting dust storms. weather patterns that lead to dust outbreaks can be simulated using computer models that support a wide range of simulations related to the long-range transport, dispersion, and depos...

Introduction: Dust devils on Mars could be an important mechanism for delivery of dust into the Martian atmosphere. Suspended dust in the Martian atmosphere is observed to be ~1-2μm in diameter [1,2,3] and calculations of fall-out rate [4,5] imply an ongoing supply of this fine dust to the atmosphere. Laboratory wind tunnel experiments [6,7], however, suggest that entrainment of fine dust into ...

A study of the acute and chronic changes in ventilatory capacity ofworkers in Lancashire cotton mills. A prospective study of workers in 14 cotton and two man-made fibre spinning mills in Lancashire was carried out over a three-year period. A questionnaire on respiratory symptoms was completed at the start of the survey and again two years later. Up to six measurements of ventilatory capacity w...

This paper presents the first study of the modulation of polar mesospheric winter echoes (PMWE) by artificial radiowave heating using computational modeling and experimental observation in different radar frequency bands. The temporal behavior of PMWE response to HF pump heating can be employed to diagnose the charged dust layer associated with Mesospheric Smoke Paricles (MSP). Specifically, th...
