Resumen
In this article, some results of numerical prediction of binary tropical cyclones (or binary systems) paths are presented. The analyzed systems were produced between 1984 and 2005, southward of 20º North latitude on northeastern Pacific Ocean adjacent to México. In this zone, it is common that tropical cyclones be accompanied by cloud clusters or another tropical cyclone that might be a mesoscale convective system, (MCS), a tropical depression, a tropical storm or a hurricane, establishing an interaction that is able to affect their typical tracks. When simulating a binary system in this work, the ability of the model to predict the path of this kind of tropical cyclones was improved. In all cases, western coast of México was affected by this kind of systems.
