The measure device for measuring and control of light conditions of plant growth
Oupický, Pavel
This report describes the special radiometers for the measurement of light condition for plant growth, which were developed in the Optical Development Workshop of AS in Czech Republic. It was published on the conference with international participation called „The man in his terrestrial and space environment“ which took place in th Upice town 2005 year.
Characterization of the acoustic-gravity waves observed in the electron concentration mesured via vertical ionospheric sounding using wavelet anaysis
Šauli, Petra ; Abry, P. ; Boška, Josef ; Potužníková, Kateřina
Description of the oscillations in the electron concentration in the F region ionosphere using wavelet analysis allows detection of the wave-like structures, that could be „invisible“ for classical spectral analysis. Suitable choice of mother wavelet and sampling period, it is possible to find coherent structures in the wide range of the ionosphere. This aproach allows to improve localiyation of the wavelike structure, find propagation parameters and locate the source region of the propagation.
Effect of solar activity on the modes of variability of atmospheric circulation
Huth, Radan ; Pokorná, Lucie ; Bochníček, Josef ; Hejda, Pavel
Solar activity effect on relative intensity and the range of variability modes has been proved.
Solar activity, interplanetary medium and possible correlations with the incidence of sudden cardiovascular events
Sitar, J. ; Střeštík, Jaroslav ; Novák, M.
Authors have been dealing since 1986 with the investigation of possible correlations of changes of solar activity and space weather with the incidence of sudden cardiovascular events and their mortality.
The change of the continentality of climate in connection with the global climatic change
Střeštík, Jaroslav
In connection with the long-term climatic change, manifested especially by the global warming, a question appears, whether the climate in our country, or in Europe in general, is going to be more continental or more oceanic.
Seismological station Úpice
Zedník, Jan
Seismological station Úpice was established by the Geophysical Institute ASCR at the Astronomical observatory in Úpice in 1986. Digital acquisition system was installed in the station in 2003. Data are transmitted in real time by Internet to the Geophysical Institute in Prague for a joint analysis with other stations of the Czech Regional Seismic Network.
Solar energetic events in the years 1996-2004. Analysis of their geoeffectivness
Bochníček, Josef ; Hejda, Pavel ; Horáček, Josef
Data concerning solar energetic events published in the years 1996-2004 by the USAF/NOAA in the form of their daily reports were collected. Analysis of individual event types shows that the degree of their geoeffectivness depends both on their size and on their solar disc location. The results are summed up in tables and scatter graphs.
