Results of Russian studies on cloud physics, precipitation, and weather modification in 2015–2018 are presented based on a survey prepared for the Russian National Report on Meteorology and Atmospheric Sciences to the 28th General Assembly of the International Union of Geodesy and Geophysics. Results concerning general issues of observation and modeling of clouds and precipitation, including convective clouds, issues of studying microphysical and optical characteristics of clouds, and weather modification are discussed.
