AB: The air ionization in troposphere leads to formation of the large charged clusters of the aerosol size due to water molecules attachment to the new formed ions. This process have several consequences leading to the changes of the air conductivity, formation of large scale space charges and large scale electric field, changes of the air temperature and relative humidity. All these effects were observed experimentally within the interval of two weeks before the strong earthquakes such as Colima earthquake in Mexico (M7.8) on 22 of January 2003 or Parkfield earthquake in USA (M6) on 28 of September 2004. In the case of earthquakes the atmosphere electricity modification is ascribed to the radon ionization and the effects are calculated within the frame of the seismo-ionosphere coupling model. But there are very few systematic sources of the radon monitoring, so the real check of the model is better possible within the frame of the controlled active experiment. Such experiments of the artificial ionization were conducted in Mexico using the large wire antennas producing the air ionization by applying the large electric potential (~ 40 kV) to the elevated circular thin wire of ~ 100 m diameter. It was demonstrated that such impact on the atmosphere can create the effects of the meteorological scale producing the artificial clouds (and rains), and even modify the large scale atmospheric formations as typhoons. Results of the theoretical estimations and active experiments will be demonstrated.
