Microwave (MW) and millimeter-wave (mmW) propagation are severely affected by dust storms and sand storms in arid and semi-arid areas. Electromagnetic waves may suffer from attenuation due to suspended particles during a dust storm. This paper proposes an empirical model to predict the attenuation due to dust storms based on a one-year measurement of visibility, humidity and their effects on MW links...
Sand and Dust storms have the potentiality of causing microwave degradation for substantial percentage of time which can lead to drop in the availability and quality of services rendered by communication systems. This paper investigates induced cross-polarization by dust storms at MMW bands. It introduces a model factor to calculate phase shift and attenuation which are to be used as inputs to cross-polarization...
Dust storms are significant meteorological phenomena which attenuates signal level especially at Ku band and higher frequencies with direct impact on telecommunications system performance. Few prediction models have been developed to calculate the attenuation due to dust storm in dB/km. All prediction models have assumed that the intensity of dust storm is uniformly distributed around the area covered...
In this paper an adjustment factor which reflects the vertical variation of dust storm (earth satellite links) has been derived based on the analysis of the vertical dust storm behavior. The paper has been divided to four parts. First an introduction to the dust storm phenomena and its effect on microwave signal attenuation. Secondly, observations of the behavior of the vertical dust storm intensity...
