Since 1998, the Institute of Terrestrial Magnetism, Ionosphere, and Radio Wave Propagation (IZMIRAN) has had an operating heliogeophysical service—the Center for Space Weather Forecasts. This center transfers the results of basic research in solar–terrestrial physics into daily forecasting of various space weather parameters for various lead times. The forecasts are promptly available to interested consumers. This article describes the center and the main types of forecasts it provides: solar and geomagnetic activity, magnetospheric electron fluxes, and probabilities of proton increases. The challenges associated with the forecasting of effects of coronal mass ejections and coronal holes are discussed. Verification data are provided for the center’s forecasts. 相似文献

Based on the data of deepwater measurements of the electric field’s vertical component in Lake Baikal, the relationship between electric field variations and those in background X-ray solar radiation has been revealed. A high correlation between these variations within periods of more than three months has been discovered. 相似文献

The long-term deep-water measurements of the vertical component of the electric field on a surface-lakebed base revealed unexpectedly high interannual changeability in the amplitudes of its variations in periods ranging from a few hours to several months. This changeability almost equally affects the field components caused by the induction in the water flows and, supposedly, by the closing current of the global electric circuit above the rift fault. We present the evidence for the correlation of this effect with the interannual variability in meteorological activity. However, the physical background of this correlation is trivial only for the electric component associated with the induction and still remains unclear for the field component caused by the closing current, which has much higher amplitude. 相似文献

Long-term observations of the electric field vertical component in Lake Baikal (preliminary results)
V. S. Shneer S. P. Gaidash I. L. Trofimov S. M. Korotaev T. V. Kuznetsova L. B. Tsirulnic A. I. Panfilov N. M. Budnev R. R. Mirgazov 《Izvestiya Physics of the Solid Earth》2007,43(4):331-335
A deep-water station is constructed for measuring the vertical component of the electric field on the surface-bottom base. A long-term experiment of measuring the vertical component in Lake Baikal is carried out. The measured signal fully reflects (due to the absence of the telluric component) variations in total flows in the range of periods from a few hours to tens of days. The coefficient of internal turbulent friction is estimated from the divergence between theoretical and experimental periods of the inertial flow. The detection of spectral maximums corresponding to variation periods of the hard component of solar radiation is the most important result of the present study. Possibly, this fact is direct evidence for the global electric circuit closure under suitable regional conditions. 相似文献

It has been indicated that 2007 is the year with clearly defined indications typical of a deep solar cycle minimum. In this case this year has no analogs for the entire period of regular solar and geomagnetic parameters concerning very many parameters. The specific behavior of different solar and magnetic activity indices in 2007 has been indicated in comparison with such a behavior of similar characteristics during other periods. 相似文献
