A global coupled thermosphere-ionosphere- plasmasphere model is used to simulate a family of large-scale imperfectly ducted atmospheric gravity waves (AGWs) and associated

Field-line reso- nances occur when harmonics of the eigenfrequency of the magnetospheric cavity or waveguide match the fundamental eigenfrequency or successive harmonics of

In the second case the real topography of Calabria is introduced but we ignore the sea-land contrast (the sea is substituted by ¯at land), in this case the forcing is due to

(1999) estimated the azimuthal phase veloc- ity of compressional pulsations using close conjunction of Equator-S and Geotail satellites for the 9 March 1998 event.. The

The criteria used to identify moving events are therefore (a) the derivatives must exceed threshold and (b) values exceeding threshold must be found at at least three adjacent

J. Moen et al.: Probing discrete auroral arcs by ionospheric tomography 577.. The appropriate MSP plot is shown in Fig. 5, with the region of interest being from around 11:58 to

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
