Tropical Cyclones and Possible Winter Thunderstorms on Kamchatka

The influence of tropical cyclones on the thunderstorm activity on the Kamchatka peninsula for winter thunderstorms in the 2008–2018 period is studied. The temporal variations of the quasi-static electric field and meteorological values at the Paratunka Observatory of the Institute of Cosmophysical Research and Radio Wave Propagation (IKIR) of the Far Eastern Branch of the Russian Academy of Sciences (φ = 52.97° N; λ = 158.25° E) and data on the solar, seismic, and cyclonic activities available on the INTERNET are used as an indicator of thunderstorm activity. It is shown that, in addition to from solar flares, which are accompanied by increased radiation in the visible and infrared spectra, the infrared radiation from a series of closely located epicenters of average-intensity earthquakes, as well as distant tropical cyclones in the Pacific Ocean, can be a source of powerful flows of warm and humid air for the formation of thunderstorm activity.
