Abstract Thunderstorm is a well-known and permanent source of infrasound events. Infrasound signal propagation is known as well to be dictated by atmospheric parameters like temperature and wind. In tropical region like in Madagascar, rainfall pattern is one possible technique used to explain seasonal variation of IMS infrasound network detectability. In this study, 20 years of I33MG infrasonic station bulletin was correlated to rainfall data. Infrasound bulletin is obtained from DTKPMCC software in NIAB collection, atmospheric variations are derived from ECMWF ERA5 data and precipitation data are from local meteorological service of Madagascar. Observation of rainfall as well as infrasound bulletin from 2003 to 2022 shows a correlation between precipitation and infrasound events.
