Document Summary
Lecture 4 & 5: october 20, 2014: water in the atmosphere and atmospheric stability: water in the atmosphere. Sundogs are refractions through plate-like-type ice crystal (like small prisms) during a sunset or sunrise. The angle change is greater for blue and less for red: heat is energy being transferred from one object to another. The emitted infrared radiation is proportional to the cloud top temperature, and is used in satellite images to estimate cloud top height: demo: radiometer: heat transfer by radiation. A radiometer works by light rays striking black and white panels. It will spin towards the black panels because the black panels absorb the light and heat up more. Air molecules move faster when they"re warmer, so they cause the pinwheel to spin. The warm air is going up and expanding; the pinwheel spins to try and regulate the air temperature. Lecture 5: october 22, 2014 & october 24, 2014: atmospheric stability: atmospheric stability.
