After introducing spectrometers with the energy threshold of 0.3 MeV the pattern of the thunderstorm ground enhancements (TGEs) observed on Aragats dramatically changed demonstrating multi-hour radiation. In the paper, we analyze comprehensive observations made on different time scales and energy ranges. A new model of TGE is discussed explaining much larger time of particle fluxes from clouds.
