--- - attributes: ~ caption: "This graph shows the total number of tropical cyclone days (the number of active storms on any given day) per year for the North Atlantic region west of 60°W. The data are tabulated for each of three intensity thresholds: named storms (winds of at least 39 mph), hurricanes (at least 74 mph), and major hurricanes (111 mph or more). \r\n\r\nAdding up the number of tropical cyclone days in a year across each of the three categories gives an indication of tropical storm frequency, duration, and intensity for that year." chapter_identifier: ~ create_dt: 2021-10-19T14:38:28 href: https://data.globalchange.gov/report/indicator-atlantic-tropical-cyclone-days-2021/figure/indicator-atlantic-tropical-cyclone-days-2021.yaml identifier: indicator-atlantic-tropical-cyclone-days-2021 lat_max: 55 lat_min: 0 lon_max: -58 lon_min: -106 ordinal: 1 report_identifier: indicator-atlantic-tropical-cyclone-days-2021 source_citation: ~ submission_dt: 2021-11-09T15:37:08 time_end: 2020-12-31T00:00:00 time_start: 1950-01-01T00:00:00 title: Atlantic Tropical Cyclone Days uri: /report/indicator-atlantic-tropical-cyclone-days-2021/figure/indicator-atlantic-tropical-cyclone-days-2021 url: ~ usage_limits: Figure may be copyright protected and permission may be required.
