The primary objective of Project Cyclops was to disrupt the structure of hurricanes by releasing silver iodide into their cloud systems. Silver iodide acts as a nucleating agent, encouraging the formation of ice crystals from supercooled water droplets within storm clouds. In theory, this process could alter the thermodynamics of a storm, potentially reducing its intensity.
The experiment was a joint effort between NOTS scientists and the Weather Bureau (now known as the National Weather Service, a part of the National Oceanic and Atmospheric Administration [NOAA]). A critical component of the experiment was the Cyclops device, designed to disperse silver iodide into the clouds from an aircraft. The first test was conducted over Hurricane Esther from a U.S. Naval Station in Puerto Rico. Eight Cyclops units were dropped into the northeast quadrant of the hurricane’s wall cloud.
The results were significant, with a “dramatic and radical change in the thermodynamics of the hurricane” observed for approximately one and a half hours following the seeding. The project report noted that the seeded area of the storm experienced a rapid conversion of supercooled water droplets into ice crystals. This led to the formation of a “cup-like” shape in the hurricane’s eye, with the wall cloud appearing to spread outwards. In the words of the report, “the changes in the form of the eye continued for at least an hour and a half,” during which time the eye’s shape oscillated and even resembled a figure 9 before returning to its original circular structure.
The potential implications of Project Cyclops were vast, hinting at a future where hurricanes might be influenced or weakened before making landfall. However, as the results were still preliminary, the project highlighted the need for further experimentation and development. The report concluded with a recommendation to conduct more tests and suggested using smaller Cyclops units for better dispersal and control in future hurricane modification efforts.
