Meteorologists atop Mount Washington, known for its extreme weather, recently took advantage of a rare phenomenon: rime ice formations that allowed them to engage in subarctic surfing. This unusual event showcased the unique conditions of the mountain, where freezing temperatures and high winds create stunning ice structures.
Key Takeaways
- Meteorologists surfed on rime ice atop Mount Washington.
- Rime ice can form at rates of up to 9 inches per hour.
- The last significant rime ice wave occurred nearly two years ago.
- Mount Washington is known for having the world’s worst weather.
The Rare Ice Wave
Mount Washington Observatory, located in New Hampshire, is famous for its harsh weather conditions, including an average temperature of 27 degrees Fahrenheit and frequent fog. Recently, after several days of freezing temperatures and high winds, the summit experienced a rare formation of rime ice, which occurs when liquid water droplets from fog freeze upon contact with cold surfaces.
The meteorologists at the observatory, including Charlie Peachey, Alex Branton, and Alexis George, seized the opportunity to surf on the icy formations. Peachey noted that the rime ice wave on the observatory’s tower had not formed in nearly two years, making this event particularly special.
The Science Behind Rime Ice
Rime ice is a unique weather phenomenon that can accumulate rapidly under specific conditions. Here are some key points about rime ice:
- Formation: Rime ice forms when supercooled water droplets freeze upon contact with surfaces at or below freezing temperatures.
- Accumulation Rate: It can accrete at rates reaching up to 9 inches per hour, depending on the environmental conditions.
- Visual Impact: The resulting ice formations can create stunning visual displays, often resembling waves or other intricate shapes.
The Experience of Subarctic Surfing
The meteorologists shared their experiences of surfing on the icy summit, highlighting both the challenges and the thrill of the activity. Despite the extreme cold and harsh winds, the team managed to enjoy a rare moment of fun amidst their rigorous data collection duties.
- Safety Precautions: The observatory emphasized the importance of dressing appropriately for the extreme conditions, warning that the casual attire seen in the surfing photos is not suitable for winter conditions on the summit.
- Daily Operations: Weather observers at Mount Washington maintain a 24/7 presence, collecting data every hour to support National Weather Service forecasts, often using Snowcat vehicles for transportation during severe winter weather.
Conclusion
The recent subarctic surfing event atop Mount Washington not only provided a unique spectacle but also highlighted the extraordinary weather phenomena that occur in this region. As meteorologists continue to brave the elements to gather critical weather data, moments like these remind us of the beauty and unpredictability of nature.
