The aim of this guide is to present the meteorological student and operational forecaster the current techniques available for interpreting satellite and radar images of weather systems in mid-latitudes of South America. Most of the books and/or guides about identification and interpretation of meteorological images from satellites and radars are dedicated to weather patterns observed over the Northern Hemisphere and tropical latitudes. As a supplement to existing manuals and guides, this new guide presents a variety of products over South American mid-latitudes. The present guide was initiated with satellite images obtained by Internet from NOAA/AVHRR and GOES-8 and with data recorded by an old radar M-33 located in Ezeiza Airport, close to Buenos Aires City (34°30’S, 58°20’W). By the end of 1998, the Department of Atmospheric Sciences of the University of Buenos Aires acquired three stations to receive NOAA-AVHRR, GVAR images and WEFAX respectively. This material will be used for teaching and research. For this reason an archive is being prepared with several examples. The selected images are being matched with conceptual models and weather charts.  This type of presentation allows the user the identification and interpretation of images as easy and quickly as possible. Patterns observed in satellite and radar images are explained in terms of basic typical airflows. It is not a finished work; it is rather the beginning of a hard and challenging task that will require the participation of a number of collaborators, many more than the ones who prepared this presentation.  In this opportunity some examples are presented such as the development of Mesoscale Convective Systems, the evolution of cold fronts as they cross the Andes barrier and the formation and dissipation of fog and stratus.
