1 | In this article an attempt is made to correlate an average number of thunderstorm days per annum with an average number of lightning discharges to the ground for each landscape. This is based on comparing visual lightning observations aver¬age multiannual values of thunderstorm activity and the data of a density of lightning discharges to the ground, obtained with a multistation system locating thunderbolts to the ground. The results can be use for estimation of dangerous from thunderstorm in regions without instrumental lightning observations | 1010 | ||||
2 | Article reveals the history of an investigation of the atmospheric electricity in Tomsk. We review first presentation of native people in Siberia about lightning, first scientific investigations of atmospheric electricity in Tomsk State University. We describe modern investigations of thunderstorm activity in Tomsk Polytechnic University and Tomsk State Pedagogical University. Keywords: atmospheric electricity, thunderstorm activity, lightning flash counters | 903 | ||||
3 | Statistical analyses of the temporal and spatial variations of cloud-to-ground lightning (lightning discharges density, polarity of lightning strokes, peak current lightning flashes) in moderate latitudes of Northern hemisphere are introduced. The database of the investigation of more 10 million of lightning strokes in Germany covers the period 1995–2006 years. Keywords: lightning flashes, lightning discharges density, peak current lightning flashes, positive and negative lightning strokes | 862 | ||||
4 | A comparative analysis of the thermodynamic parameters of the atmosphere, obtained by the radiosonde data of the station Novosibirsk and data of thunderstorms and heavy rains of meteorological station Ogurzovo for the summer seasons of 2000–2011 are introduced. The limits of variability and characteristics of some parameters (SHOW, CAPE, TOTL, KINX, LIFT, EQLV, LFCT) during thunderstorms and heavy rains were determined. Keywords: thunderstorm, heavy rain, thermodynamic parameters, convection in the atmosphere, intervals of variation of thermodynamic parameters | 1036 |
