Quick Answer
Igloos can provide moderate protection from high winds but are not entirely effective against extreme gusts. This is due to their relatively lightweight structure and the potential for snow to be stripped away by strong winds.
Igloo Design and Wind Resistance
When constructing an igloo, it’s essential to focus on building a sturdy, well-insulated structure that can withstand harsh weather conditions. Ideally, an igloo should be built with blocks of snow that are at least 2-3 times larger than the previous layer, allowing for a strong and stable foundation. This technique, known as “layering,” helps distribute the wind load more evenly across the igloo’s surface.
Wind-Resistant Techniques
To enhance an igloo’s wind resistance, you can employ a few specific techniques. One approach is to build a “wind tunnel” around the entrance, which involves creating a narrow, curved passage that helps to reduce wind velocity before it reaches the main body of the igloo. You can also use a technique called “snow anchoring,” where you dig a trench around the perimeter of the igloo and fill it with compacted snow, creating a solid anchor for the structure.
Traditional Igloo Construction
In Inuit culture, igloos were traditionally built as emergency shelters, often in areas with relatively calm weather. To construct a wind-resistant igloo, the Inuit used a combination of techniques, including layering, wind tunneling, and snow anchoring. They also built igloos in areas with natural windbreaks, such as behind hills or outcroppings of rock. By combining these techniques and situational awareness, the Inuit were able to create shelters that could withstand even the most extreme Arctic weather conditions.
