Persistence of the planetary wave type oscillations in foF2 for four European stations.

Popis výsledku v původním jazyce

Planetary waves are oscillations of very predominantly tropospheric origin with typical periods of about 2-30 days. Their dominant zonal wave numbers are 1, 2 and 3, i. e. the waves are of large-scale (global) character. The planetary wave type oscillations have been observed in the lower and middle atmosphere but also in the ionosphere, including the ionospheric F2-layer. Here, we deal only with the oscillations analyzed for four European stations over a solar cycle with the use of the Meyer and Morletwavelet transforms. Waves with periods near ř, 10 and 16 days are studied. Only events with a duration of three wave-cycles and more are considered. The 5-day period wave events display a typical duration of 4 cycles, while 10- and 16-day wave events are less persistent, with a typical duration of about 3.5 cycles and 3 cycles, respectively. The persistence pattern in terms of number of cycles and in terms of number of days is different. In terms of number of cycles, the typical persist
