Global Identification of Previously Undetected Tropical Cyclone Candidates in NOAA/CIRES 20th Century Reanalysis DataThis research expands the scope of the original methodology by presenting a filtering algorithm that dramatically improves the efficiency and speed with which candidate events are identified and...
First, a series of atmospheric proxies of TC passage in the NOAA/CIRES 20th Century Reanalysis dataset are constructed for the satellite-era. Next, similar magnitude signatures (not corresponding to known Best-Track TCs) are identified in the pre-satellite era and subjected to further synoptic ...

Quantity of each candidate event type found using the manual process compared with the quantity found in both the manual process and the algorithmic method. As determined by ...
Extratropical cyclone (ETC) climatologies in the Northern Hemisphere are analyzed from 1891 to 2005. Sea level pressure fields from the 20th Century Reanalysis (Compo et al, 2010) were used to identify ETCs and assemble tracks. Transformation of the data into an equal area coordinate system and ...
