Results of Atmospheric Electricity and Meteorological Observations, S. Kalinowski Geophysical Observatory at Świder, 2007–2010 Kubicki, Marek; Piłacik, Alicja Atmospheric electricity yearbooks have not been published since 2007. This was the result of the start of operation of the automatic database in which atmospheric electricity measurement data are recorded with high time resolution (1 or 10 seconds). In order to maintain the continuity of the form of the data presented in the Yearbooks of Atmospheric Electricity, a decision was made to resume publication. The presented publication contains a set of data for the years 2007–2010. The data contained in the yearbooks can be directly used for annual, seasonal, and daily analysis.

Sensitivity of the GEM Model to Different Descriptions of City Surface Parameters over Warsaw Sattari, Anahita Over half of the world’s population lives in urban areas, even though urban agglomerations cover only 0.05% of the Earth’s surface. Urbanisation significantly modifies the surface level’s moisture, radiation balance, thermal stability, and aerodynamic properties. The physical processes in the urban surface layer directly influence the atmosphere above and, specifically, the atmospheric boundary layer. Thus, understanding and modelling these processes are necessary for studying the urban meteorology. The primary objective of the presented research was to assess the impact of the urban land cover on the development of the atmospheric boundary layer over Warsaw. To carry out the objective, a high-resolution version of the Global Multiscale Environmental model was used to examine its ability to reproduce the diurnal cycle of the meteorological parameters, including the thermal and turbulent structure of the atmosphere. The Town Energy Balance (TEB) parameterisation was used to represent urban effects on modelled meteorological parameters at the final nesting level with a horizontal resolution of 1 km over Warsaw. Mid-high buildings, sparse buildings, industrial areas, roads and parking spaces, and a mix of built and nature are the urban cover categories used in the TEB parameterisation. Four one-day cases representing different meteorological conditions and seasons were selected for modelling.

Atmospheric Electricity: Papers on Thunderstorm and Cloud Electricity Problems of thunderstorm and cloud electricity still remain in the mainstream of research of atmospheric physics researchers. Hence, in this special issue of Publications of the Institute of Geophysics, Polish Academy of Sciences, devoted to problems of atmospheric electricity, we present a set of six articles in which we publish some recent results on this subject, obtained by us and our co-workers. The article by Barański and Guzikowski shows how detections of cloud-to-ground lightning sources obtained from the Local Lightning and Detection Network (LLDN) operated in the Warsaw region can be supplemented by computer simulations of radar reflectivity, as well as dynamic and electric field structure of the considered thunderclouds in the WRF and WRF_ELEC models we used. In another article, Odzimek et al. describe meteorological and atmospheric electricity datasets and the methodology of analysing the atmospheric electric data from the Polish Atmospheric Electricity Observation Network used for the purpose of research studies on the electricity of Nimbostratus and Stratus clouds. Next, a series of three articles by Odzimek et al. summarise optical observations of sprite lightning Poland, made in Gliwice and Świder over 2011–2015. Finally, the article by Parfiniewicz et al. presents a new idea of using the virtual Fujita scale [VFS] number approach to assessment of lightning discharges development and severity for the derecho episode in Poland on 11 August 2017. It should be noted that for the first time the lightning detection data from the PERUN remote sensing system in Poland were successfully applied for the determination of the whole trace of a Mesoscale Convection System (MCS) with the derecho incident. This MCS was organised in the form of a very extended supercell. We have tracked the time development of such supercell with high spatial and temporal accuracy that would be impossible to obtain by using the routine radar data only.

Atmospheric Ozone, Solar Radiation, 2004-2005 Ozone observations have been made by means of Dobson spectrophotometer No. 84 in the Geophysical Observatory at Belsk since March 1963. This publication presents all total ozone values and vertical distribution of ozone over Belsk in 2004 and 2005 obtained from the conventional Umkehr observations.
