V.E. Zuev Institute of Atmospheric Optics of Siberian Branch of the Russian Academy of Science, 1, Academician Zuev square, Tomsk, 634021, Russia
Keywords: empirical linelists, rotational-vibrational transitions of HD18O and D218O

Abstract >>
Detailed and accurate absorption linelists are generated for the HD18O D218O molecules in the 09400 cm1 spectral range. These linelists, known as empirical lists, are based on the experimental energy levels available from the literature and ab initio transition intensities obtained through variational computations. Positions of empirical transitions are determined at a level of the best experimental accuracy, and even better in case of weak or blended lines. Averaged accuracy of calculated intensities is about 10%. Empirical lists of absorption lines of water isotopologues currently replace incomplete or low accuracy experimental data in the canonical databases like HITRAN.

Keywords: turbulence, coherent turbulence, coherent structure, topological soliton, simulation of coherent structures, hydrodynamics equations, Navier-Stokes equations, topological precursor

Abstract >>
Structure of air turbulent motion inside large specialized rooms of astronomical telescopes has been studied by numerical solving of several boundary value problems for hydrodynamics equations (Navier-Stokes). There are optical elements of large-aperture telescopes inside such rooms. The main attention is devoted to closed rooms with different heating the upper and lower surfaces without exchange of internal and external medium through the borders. This enables the testing under steady state conditions of the optical characteristics of astronomical telescopes including their resolution. In particular, a visualization of the air flow motion by streamlines allows one to analyze the impact of design features of telescope and the temperature regime of its optical elements. Results of our numerical simulations demonstrate that the solitary large vortices (coherent structures, topological solitons) are observed inside specialized rooms. The cascade decay of such vortices leads to the coherent turbulence. The simulations confirm our previously experimentally stated conclusion that the mixing of coherent structures of different close-by sizes (and close-by frequencies of major vortices) results in the non-coherent Kolmogorov turbulence.

Abstract >>
The paper presents the results of the statistical analysis of characteristics of the lower stratiform clouds, obtained according to the 8-term meteorological observations of 60 Siberian stations for the last 45 years (from 1969 to 2013).

Keywords: tropical cyclones, thunderstorms activity, lightning localization, very low frequency radiation

Abstract >>
Synoptic and mesoscale weather systems over ocean and seas are often accompanied by lightning activity, which intensity and spatial distribution is modulated by the dynamic structure of these weather systems. Lightning discharges are the sources of electromagnetic radiation in very low frequency range (VLF) and are registered by VLF direction finders. Using the World Wide Lightning Location Network (WWLLN) the relations of characteristics of lightning fields in the North-Western Pacific Ocean with the characteristics of the fields of meteorological elements of weather formations, estimated by remote sensing data from satellites, are study through examples of tropical cyclones. The technique is illustrated allowing binding parameters of thunderstorm activity (frequency and intensity, spatial distribution of lightning) with the structure of weather systems over the oceans and seas, the intensity and shape of mesoscale structures in these systems, allocated to the fields of the vortex drive wind scatterometers and satellite images in the visible and infrared bands. On the example of separate tropical cyclones (TC) for 20122013, the relation of lightning discharge frequency and density in the area of influence of a TC with spatial distribution of driving ocean wind vortex is shown.

Abstract >>
A study was made of the pollen particle sedimentation of the weeds of several species growing in Western Siberia. The percentage of individual grains and their agglomerates resulting from spraying was calculated. The sedimentation rate of aggllomerates, consisting of one to six pollen grains, was determined. The sedimentation rate of agglomerates was found to depend on the number of the pollen grains involved.

Keywords: breakdown of atmospheric pressure air in non-uniform electric field, experimental simulation of bead lightning, runaway electrons

Abstract >>
The breakdown initiated by runaway electrons in non-uniform electric field in atmospheric pressure air was investigated. Bright plasma channels (like filaments) in the center of the discharge gap was observed on the background of the diffuse discharge at applying high-voltage pulses with an amplitude of about 200 kV across the discharge gap with interelectrode distance of 18 mm. Occurrence probability of the ones was no more than 10%. Glow of the bright plasma channels are similar to the one of a spark. It was found that the bright plasma channels appear on the decline stage of the discharge current. Radiation intensity of the one is an order of magnitude less than that of the diffuse discharge. Furthermore, the bright plasma channels was observed in pulse-periodic discharge. In this case, nanosecond voltage pulses with an amplitude of 1015 kV was applied across the discharge gap with interelectrode distance of 6 mm. Pulse repetition rate was 400 Hz. Occurrence of the bright plasma channels on the background of diffuse discharge is due to generation of runaway electrons and the discharge current redistribution in cross-section of the discharge plasma on the decline stage of the discharge current. It is assumed that the registered form of the discharge is analog of bead lightning observed in the Earth's atmosphere.
