IX.2 Hurricanes & Tropical Storms—Locations and Intensities since 1851
Created by cartographer and designer John Nelson, this map visualizes over 160 years of recorded tropical storms and hurricanes by their paths and intensities, sourced from NOAA archives made available to the public. Mapping large volumes of this sort of recurring phenomena reveals clearer and stronger footprints of structure that may not be as apparent when presented individually. Inherent in the mapping, and highlighted via the polar projection, is the circuitous nature of cyclonic patterns as they spawn in warm tropical waters and rush away from the equator, carried along by climatic forces ultimately tied to the rotation of the planet itself. When viewed broadly in temporal volume and geographic scale, the cyclonic structure of individual hurricanes is echoed by a macroscopic view of this planetary phenomenon, forming one large “hurricane.” This fractal-like repeating pattern is a reminder of the repeating order found throughout the universe. In this case, a single rotational body, when seen at the right scale, forms a collective rotational body at the planetary level—a pattern then repeated at the solar system and galactic scales. The second and perhaps more salient message of this visualization is the evidence of increasing efforts and confidence in detecting and tracking these storms. The timeline plots the overall energy measured each hurricane season. The precipitous increase of detection in recent decades illustrates the narrative of important investments in the sciences—and the human dividends into which that investment has paid.
