Abstract. The generation of Hall and ®eld-aligned currents in and in the vicinity of nighttime mid-latitude sporadic E-layers moving under the action of strong acoustic impulses

Rely- ing on results published in the open literature, we inferred that the characteristics of the long-term peri- odicities in 50 MHz coherent echo and strong Es occurrence, that

Ionospheric measurements of relative coronal brightness during the total solar eclipses of 11 August, 1999 and 9 July, 1945... Ionospheric measurements of relative coronal

In these three examples it was found that, within the error limits and at least at one ofthe receiver sites, the perpendicular anisotropy is aligned in the direction of the plasma

The potential and the FAC have the same sign so this event could support the upward extended U-shaped potential picture, but the magnitude of the potential (1 kV) is small. Among

In the atmospherics record we observed long-period fading in the noise level closely associated with the meteorological activity during the ¯ood-rainy days.. Observations of

abies may be either limited soil water reserves or atmospheric evaporative demand depending on the current level of the vapour pressure de®cit.. As the soil dries the stomatal

Assuming a wave source at the auroral electrojet height of ∼125 km, and wave ascent an- gles consistent with the properties of gravity waves, we find source locations for the
