Meteorologists have been measuring these temperature shifts for decades in three phases: Positive, neutral and negative.

几十年来，气象学家一直将这些温度变化分为三个阶段: 正、中和和负。

These mirrors still create a dangerous temperature shift for local wildlife, but they have less potential to transform the landscape.

这些镜子仍然会对当地野生动物造成危险的温度变化，但它们改变景观的潜力较小。

These mechanisms are controlled by the brain's hypothalamus, which detects minute temperature shifts and sends signals throughout the body accordingly.

这套机制通过大脑的下丘脑控制，下丘脑可以检测微小的温度变化，并通过变化向身体发送信号。
