The RAS, “Robot Antartico di Superficie”, is intended to operate in a hostile and generally unknown environment, where the ability of sensing obstacles or special features (crevasses, sastrugi, composition of the soil) can represent the key point to successfully perform the required mission or to fail: wind storms (and many other atmospheric phenomena giving rise to white out) can make useless ...

We describe an automatic storm-tracking system to help Doppler radar system to detect severe storms such as thunderwith the forecasting of severe storms. In this article, we present the storms and tornadoes. The Doppler radar generates intensity and concepts of fuzzy point, fuzzy vector, fuzzy length of a fuzzy vector, radial velocity images, examples of which are shown in Figures and fuzzy ang...

[1] First results are presented of an effort to model the storm-time distortion of the magnetic field in the inner magnetosphere using space magnetometer data. Strong geomagnetic storms are relatively rare events, represented by only a small fraction of the data used in the derivation of existing empirical geomagnetic field models. Hence using those models for the mapping of the storm-time magn...

Comprehensive catalogues of ancient sunspot and auroral observations from East Asia are used to identify possible intense historical geomagnetic storms in the interval 210 BC–AD 1918. There are about 270 entries in the sunspot catalogue and about 1150 entries in the auroral catalogue. Special databases have been constructed in which the scientific information in these two catalogues is placed i...

Ice storms, or icing events, are important meteorological disturbances affecting forests over a surprisingly large portion of the USA. A broad belt extending from east Texas to New England experiences major ice storms at least once a decade; and truly major events occur in the heart of this belt once or twice a century. In the areas most affected, icing events are a factor that shapes stand com...

This work analyzes several remote sensing instrument capabilities in monitoring dust storms. Multisensor data analysis is carried out to study the behavior of dust particles at different wavelengths. A technique based on a combination of optical and microwave sensing of dust storms, using the Moderate Resolution Imaging Spectrometer (MODIS) and the Tropical Rainfall Measuring Mission (TRMM) Mic...
