Variations in the sky brightness during a lunar eclipse
A total lunar eclipse is conjectured to have influence on the physical conditions of an environmental area, particularly on the brightness of the sky. The phenomenon might also be relevant on weather parameters change on Earth, such as temperature, humidity and pressure, though a straightforward correlation is not easy to establish. This work mainly aims at measuring the brightness of the sky a...
متن کاملOn the Geomagnetic Lunar Daily Variation Field
The geomagnetic lunax daily variation field, L, was studied using all available results of lunar analysis of geomagnetic data from a total of 37 stations. Equivalent external (overhead) and internal (induced within the earth) electric current systems responsible for L variations with respect to dip latitude were estimated by the method of spherical harmonic analysis for each season. The externa...
متن کاملdetermination of the electrical conductivity and temperature of the upper mantle using geomagnetic quiet-daily variations
the electrical conductivity of the earth is its physical parameter, which can be studied in global scales. the investigations of the earth's electrical conductivity are based on geomagnetic field variations. time variations of the geomagnetic field consist of long-term and short-term (transient) variations. external sources induce electric currents into the earth. the induced electric curr...
متن کاملSeasonal variations in daily rhythms of activity in athletic horses.
Circadian rhythms reflect extensive programming of biological activity that meets and exploits the challenges and opportunities offered by the periodic nature of the environment. In the present investigation, we recorded the total activity of athletic horses kept at four different times of the year (vernal equinox, summer solstice, autumn equinox and winter solstice), to evaluate the presence o...
متن کاملSeasonal variations of daily mortality in Tokyo City.
Daily deaths of all causes in Tokyo residents from 1966 to 1972 were analyzed with relation to environmental conditions. As the analytical methods, daily deviation from 15-day moving average, simple correlation coefficients and stepwise regression procedure between daily deaths and environmental variables were employed. Seasonal variations of daily deaths, high in winter low in summer, and sign...
