Argentina is located in the south of South America, being one of the 200 countries in the world with one of the largest territorial extension, so it exhibits different topographic and climatic characteristics, which makes it unique. The Andes Mountains, the natural boundary between Argentina and Chile, is one of the natural conditions that influence the climate in the country.In the present work, the spatial distribution and historical evolution of the stormy day in Argentina was studied. Discrete surface synoptic observations (SYNOP messages ) such as those reported in different conventional weather stations of the National Meteorological Service (SMN) and continuous information observed by the WWLLN detection network were used, understanding as a Thunderstorm day (Td)that day when an observer hears thunder at the weather station in the first case or when the World Wide Lightning Location Network (wwlln.net) detects at least one electrical discharge during the day in a certain area centered on the station, in the second case. Thus, one of the main challenges was to achieve a good integration of these two sources of information.
