Solar and geomagnetic activity effects on the troposphere behaviour in winter 1981/1982
Bochníček, Josef ; Hejda, Pavel ; Huth, Radan
Tha association between the changes in solar/geomagnetic activity and changes in the lower atmosphere pressure, temperature and wind fields was analyzed for the Northern Hemisphere winter of 1981/1982.
Long-term period of the solar activity lasting 106 years and its connection to the planets of the solar system
Čech, J. ; Střeštík, Jaroslav
A secular period of solar activity lasting about 1172 years and its connection to heliocentric coordinates of the positions of the biggest planets of the solar system is being discussed.
Middle-term changes in the lengths of solar cycles
Střeštík, Jaroslav
In the published data of anuual sunspot numbers since 1500 and less reliable guesses of positions of minima and maxima of solar cycles since 200 B.C. middle-term changes in the cycle lenghts have been investigated. Data published by different authors differ considerably, the more the further to the past they go.
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.
Trains in our world
Rajchl, Jaroslav
According to e.g. St. Thomas the human history is connected with the mankind behaviour which is well known is tighly connected with the solar activity during its 500 year periodicity. Owing to this activity trains of various shapes and duration are induced; they are in an interesting correspondence to different typical processes in the mankind history.
Solar activity and trains
Klimeš, J. ; Rajchl, Jaroslav
Solar activity in the form of even and odd cycles as the process influencing various types of trains is discussed.
Solar and geomagnetic activity effects on wind fields in the Northern hemisphere winter lower troposhere
Bochníček, Josef ; Hejda, Pavel
The magnitude and prevailing direction of winds in the lower troposphere were analysed in the Northern hemisphere in the winter periods of the years 1964, 1967-1969, 1971-2001. Composite maps of those winds showed marked differences, in particular between the maps in which both activities were simultaneously low or high.
Solar activity as a consequence of the solar system origin
Čech, J. ; Kotrč, Pavel ; Křivský, L. ; Klimeš, J.
A similarity of the orbital periods of planets and those iccuring in the solar activity is discussed.
Methodology of the search of rapid changes of the H-alpha chromosphere brightness
Kupryakov, Yu. A. ; Kotrč, Pavel ; Havlíčková, E.
Methodology of searching fast changes in the chromosphere H-alpha brightness during solar flares is discussed.
