Addition et Soustraction d'un Nombre à 6 Chiffres par un Nombre à 6 Chiffres SANS retenue (Gros Caractère) (A)

This event is a very good example of an appearance of a strong westward electrojet in the evening sector at all EISCAT magnetometer cross stations. The maximum of the negative

A few of the difficulties in accurately modelling high-latitude electron densities with a large-scale numer- ical model of the thermosphere and ionosphere are ad- dressed by

The evolution, and dynamics of Es clouds can be studied from backscatter data obtained by the different radar beams over a period of time.. Velocities can be determined by plotting

Lors- qu’on ne sait pas si le verbe est au mode indicatif ou subjonctif parce qu’il se prononce de la même façon, on suggère de le remplacer par un verbe comme faire ou partir, dont

A comparison of results obtained using steady-state and time-dependent models with the same mean conditions (cross-polar-cap voltage, »pc, and polar cap area) has been undertaken

They were later discriminated into tangential or rotational according to their characteristics: the former possess no ®eld normal to the discontinuity surface but show a

The height-latitude contour plots of monthly mean zonal and meridional winds for all months of the year, and of annual mean wind, amplitudes and phases of annual and

change in the calculated wave azimuth. W can also be calculated from the average of the line-of-sight velocities in the o€-vertical beams, i.e. Figure 6 shows a visible-light
