AbstractThe Carte Synoptique catalogue of solar filaments from 1919 March to 1957 July, corresponding to complete cycles 16-18, is utilized to show the latitudinal migrations of solar filaments at low (=50 degrees) and high (>50 degrees) latitudes and the latitudinal distributions of solar filaments for all solar filaments, solar filaments whose maximum lengths during solar disk passage are less than or equal to 70 degrees and solar filaments whose maximum lengths during solar disk passage are larger than 70 degrees. The results show the following. (1) The latitudinal migrations of all low-latitude solar filaments and low-latitude solar filaments whose maximum lengths during solar disk passage are less than or equal to 70 degrees follow the Sporer sunspot law. However, the latitudinal migration of low-latitude solar filaments whose maximum lengths during solar disk passage are larger than 70 degrees do not follow the Sporer sunspot law: there is no equatorward and no poleward drift. The latitudinal migration of high-latitude solar filaments whose maximum lengths during solar disk passage are larger than 70 degrees is more significant than those of all high-latitude solar filaments and high-latitude solar filaments whose maximum lengths during solar disk passage are less than or equal to 70 degrees: there is a poleward migration from the latitude of about 50 degrees to 70 degrees and an equatorward migration from the latitude of about 70 degrees to 50 degrees of all high-latitude solar filaments and high-latitude solar filaments whose maximum lengths during solar disk passage are less than or equal to 70 degrees and there is a poleward migration from the latitude of about 50 degrees to 80 degrees and an equatorward migration from the latitude of about 80 degrees to 50 degrees of high-latitude solar filaments whose maximum lengths during solar disk passage are larger than 70 degrees. (2) The statistical characteristics of latitudinal distribution of solar filaments whose maximum lengths during solar disk passage are larger than 70 degrees is different from those of all solar filaments and solar filaments whose maximum lengths during solar disk passage are less than or equal to 70 degrees ((c) 2012 WILEY-VCH Verlag GmbH & Co.
