This map product visualizes the tracks of historical hurricanes in contiguous U.S.
from
1851 to 2024. It is a continuation of my previous award-winning map Visualizing
Historical Hurricanes in Continuous U.S, with revised legend design
and updated dataset.
With all the hurricane tracks’ intensity displayed in different color-width
combination,
as illustrated in the legend, the storm category (Saffir-Simpson Hurricane Wind) is
intuitively visualized at corresponding location of tracks. Storms since 2020 have
full
opacity, and various transparency is applied to the older ones according to the
year,
imitating the fading out history, while storms before 1970 are universally grayed
out
with only 25% opacity. As for the label typography, bold text illustrates major
hurricanes (category-3 and above); hurricanes since 2000 are labeled on the ocean,
and
those before are labeled on the land, including some named storms.
Additionally, auxiliary elements (graticule, country boundary, state boundary,
hillshading, urban area) and graphic designs are deployed for visual legibility and
cartographic aesthetics.
The major data source is the International Best Track Archive for Climate
Stewardship
(IBTrACS) during 1851 - 2024, providing the location and intensity for global
tropical
cyclones. Additional data sources include U.S. Census Bureau, ArcGIS Online, and
Esri’s
World Ocean Basemap and Light Gray Basemap.
