This map product is a combination of three geovisualizations about historical hurricanes in contiguous
U.S. from different perspectives.
1. The Panoramic “Hexagon” Map (bottom): With orthographic “World From Space” projection, this map lines
up the major Atlantic coastal area of the U.S. horizontally. Based on
10-square-kilometer hexagon unit, the choropleth (color) shows the total number of storms, and the piled
bar chart (length) shows the storm frequencies in recent 10, 20, 50, 100, and
171 (all accessible history) years, correspondingly. Urban area is colored in light gray, and necessary
labels for major coastal cities are displayed.
2. The “Concentric Ring” Map (top-left): With same universal unit as the bottom map (10-sq-km hexagon),
this map uses concentric rings to compare the number of the storm events every
decade in recent 50 years: i.e. the center (core) indicates oldest decade (1970s) and edge ring
indicates the most recent one (2010s). The darker the ring color is, the more storms
this hexagon statistical unit has witnessed.
3. The “Historic Hurricane Tracks” Map (top-right): With all the hurricane tracks’ intensity displayed
in different color-width combination, the storm category (Saffir-Simpson
Hurricane Wind) is intuitively visualized at corresponding location. Storms in recent 20 years have full
opacity, and various transparency is applied according to its year, imitating
the fading out history. As for the label typography, black text indicates storms in recent 20 years,
aligned on the right side of coast; grayer text indicates storms earlier, aligned
on the left side of coast; and additionally, bold text illustrates major hurricanes (category-3 and
above). The storm’s year is added to the bracket after the name, while some
historic storms even do not have a name.
Additionally, auxiliary elements (graticule, state boundary, ocean basemap) and graphic designs
(tri-partition layout, gradient effect, drop shadow, universal condensed “Acumin”
font) are deployed for visual legibility and cartographic aesthetics.
The major data source is the International Best Track Archive for Climate Stewardship (IBTrACS) during
1851 to 2021, 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.
This map is the winner of Arthur Robinson Static Print Map Award in 50th CaGIS Map Design Competition .
It was also personally selected by Jack Dangermond, President of Esri, to be included in the Plenary Session (about 17:22) of 2023 Esri User Conference.
This map was selected by the Highlands County (FL) Board of County Commissioners, to be featured in the traveling "Map Expo" for public educational purpose. The exhibition was firstly on display in the government building for GIS Day, and then moved to 3 public libraries till mid December.
Dates & Locations of "2024 Map Expo":
1. Government Center lobby, Nov. 18-22, 2024
(600 S. Commerce Ave., Sebring)
2. Avon Park Public Library, Nov. 25-27, 2024

This map is also selected to be published on the next volume (Vol.40) of Esri Map Book, in 2025.
As Hurricane Helene intensifies in late September of 2024, discussions about the disaster preparedness of Florida and Georgia are growing. It reminds me of the map I created two years ago about historical hurricanes, so I expanded the hurricane trajectory section with updated data, including Hurricane Ian (2022) and Idalia (2023). Hope people in the affected areas could learn from the past experiences to better handle the upcoming challenges. Pray for everyone's safety.
On Nov 30, 2024, the National Hurricane Center (NHS) announces the official end of 2024 Atlantic Hurricane Season on Nov 30, with a record-breaking ramp up following a peak-season lull. As the finale, I updated this map with 18 new tracks of storms, and 5 more labels of landed hurricanes: Beryl (Juy), Debby (Aug), Francine (Sep), Helene (Sep), and Milton (Oct), in 2024.
