Abstract <p>Atmospheric turbulence is one of the most significant factors affecting the propagation of waves of various nature and the operation of devices based on their application. This paper presents the results of experimental studies of the impact of short-term heavy rainfall on subsequent changes in the meteorological and turbulent state of the ground atmosphere based on processed synchronous acoustic and optical measurements of atmospheric parameters. An assessment is made of the impact of intense precipitation on the main turbulent characteristics of the surface atmosphere, such as the energy of temperature and wind fluctuations and vertical heat and momentum fluxes. It is shown that heavy rainfall significantly changes these characteristics. The results obtained can be used to interpret optical and acoustic measurements used to study the atmosphere.</p>
