Our approach is based on a topological analysis of rainfall data allowing for the extraction of the most prominent, and hence meaningful, rainfall field maxima. Then, an ad-hoc bottleneck matching is used to track the evolution of maxima along multiple time instances. The potential of our method is exhibited through a set of experiments carried out on a collection of observed punctual rainfall data and radar measurements provided by Genova municipality and Regione Liguria. }, keywords = {Critical points, Persistence analysis, Storm tracking}, url = {http://irs.imati.cnr.it/reports/irs16-11}, author = {D.
