1 - For desert rats and camels, the problem is conservation of water in an environment where standing water is nonexistent, temperature is high, and humidity is low.

2 - Since the atmospheric pressure changes with the altitude and humidity of the air, the barometer is also used to forecast weather conditions.

3 - Even though thunderstorms are most frequently seen in tropical rainforest regions they may also occur in any other parts where there are conditions of high humidity with atmospheric instability.

4 - Humidity and precipitation provide moisture that can slow fires down and reduce their intensity, as it is hard for fuel to ignite if it has high moisture levels.

5 - People have varying sensitivities to mold, a type of fungi that grows in warm, damp, humid environments.
