| Description
| - Práce se zabývá srovnáváním krátkodobé proměnlivosti v ionosféře ve vrstvě F během měřící kampaně “HIRAC/SolarMax” (23 –29. dubna 2001). Krátkodobé fluktuace v záznamech měření ze dvou stanic Ebro (40.8 °N, 0.5 °E) a Průhonice (49.9 °N, 14.5 °E) v rozsahu period 15 minut až 2 hodiny jsou detailně analyzovány. Pravidelné vlnové struktury se objevují v elektronové koncentraci F vrstvy měřené na obou observatořích během klidných dnů. Pravidelně dochází k nárůstu vlnové aktivity po východu Slunce a v odpoledních hodinách, při západu a po západu Slunce. Sluneční Terminátor je předpokládaným zdrojem nalezených oscilací. Práce diskutuje také nepravidelné nárůsty vlnové aktivity během dne geomagneticky porušeného dne. Tyto vlnové struktury významně mění svoji charakteristiku ve výšce okolo 200km. (cs)
- Comparative studies of short-term ionospheric variability in the F region ionosphere during rapid sequence sounding campaign “HIRAC/SolarMax” (23 -29 April 2001) are presented. The ionospheric short-term fluctuations have been studied in detail using measurements from vertical sounding at Ebro (40.8 °N, 0.5 °E) and Průhonice (49.9 °N, 14.5 °E) in the period range from 15 minutes to 2 hours. Regular wave-like bursts were found during quiet days at both stations in electron concentration in F region, with an increase of the oscillation activity after sunrise and then during late afternoon, and at sunset and after sunset. Solar Terminator is assumed to be one of the sources of the regular wave bursts detected in the ionosphere during campaign HIRAC. Particular enhancement of the wave-like activity during disturbed day is discussed, being significant evidences of a change of the wave-like activity pattern at a height around 200 km.
