What natural indicators suggest a change in weather is coming?

Observing Nature’s Signs

When traversing the tundra, pay attention to changes in lichen and berry growth. A sudden increase in berry production can indicate an approaching storm, as the plants are responding to increased humidity and cloud cover. Similarly, lichens may become more vibrant or dense as a storm approaches. Observe the direction and speed of the wind, as a sudden shift or increase in wind speed can signal a change in weather.

Animal Behavior and Migration Patterns

Pay attention to the behavior and migration patterns of local wildlife, such as caribou. When caribou begin to move towards higher ground or thicker vegetation, it may indicate an approaching storm. This behavior is often a result of their keen sense of smell and ability to detect changes in barometric pressure. Observe the behavior of other animals, such as birds and insects, as they too may exhibit changes in behavior before a storm.

Permafrost and Frost Crust Indicators

In the tundra, the permafrost and frost crust can be indicative of changing weather patterns. A sudden drop in temperature can cause the permafrost to contract, resulting in a harder and more brittle surface. This can be detected by the sound of cracking and creaking when walking on the permafrost. Additionally, a change in the frost crust can indicate a change in weather, with a harder crust often indicating a more stable weather pattern.
