The study presents a comprehensive survey of thunderstorms in Southeast Asia Republic of Vietnam, Cambodia, Thailand, Laos and North Vietnam . Various Southeast Asian data sources are used, and the reliability of these sources as well as the difficulties involved in obtaining reliable thunderstorm data are discussed. The monthly and annual frequencies of thunderstorm days for 83 stations in Southeast Asia are given in both table and isoline-map forms. Year to year variations in the numbers of thunderstorms observed monthly and annually are discussed. The duration and diurnal variation of thunderstorms are also considered. A thunderstorm persistency model was developed from ten years of daily thunderstorm records for selected Thailand stations. The report shows how the local thunderstorm climatology can be approximated for a Southeast Asian location where no data are available.
