available advanced tools and techniques are also contributing toward monitoring about one additional
Atlantic tropical cyclone per year since 2002. Thus large, long-term 'trends' in tropical cyclone frequency are primarily manifestations of increased monitoring capabilities and likely not related to any real change in the climate in which they develop.

The project ranks the year 1914 as the quietest hurricane season ever for the
Atlantic basin with just one tropical storm. The project has currently reanalyzed storms from the period 1886 to 1970, with 1965-1970 period being revised in January 2022, and has extended HURDAT back to 1851. In 2001, data

1966, an average of two storms per year are missing from HURDAT. This is mainly due to a lack of satellite imagery and lack of reconnaissance aircraft prior to 1943. An additional storm per year is likely missing prior to the advent of new technologies. These technologies include satellite-derived

As early as 1957, it was recognized that an increasing trend in the number of tropical cyclones each season in the
Atlantic Basin was at least partially tied to increasing observations and better records. By analyzing the density of ship tracks over time, it has been estimated that between 1900 and

A significant amount of new data for systems between 1851 and 1886 became available after a major basin-wide reanalysis in 1996, a project led by Jose
