Relative Humidity & Temperature

Notice the great presence of a middle cloud layer (Stratonimbus). In minor proportion we can observe the presence of low and high clouds. Observe that stratonimbus has a RH value higher than low clouds.

Water Vapor

Even though the middle clouds have a higher RH value than low clouds, they have a lower amount of water vapor. In the same way, we can observe on the linear plot that high clouds (11 km) are almost imperceptibles regarding to amount of water vapor.
