Centripetal Force - A force that acts on an object moving in a curved path. Centripetal force is directed towards the center of an objects axis of rotation. This force is responsible for keeping an object moving in a curved path.

Deposition - The process where water turns directly from vapor to ice, without first becoming liquid. A common instance of deposition is when frost forms on the grass during cold mornings.

Steam Fog - The name for fog that is produced due to cold air mixing with warmer and more humid air. The most common setup for steam fog is when cold air drifts across warm water. The first cold air masses of the season that drift across lakes and rivers will often result in the creation of steam fog.

Wall Cloud - A localized, persistent, often abrupt lowering from a rain-free base of a cumulonimbus cloud. The location of the wall cloud marks the location of a strong updraft feeding the storm. Therefore, many wall clouds exhibit rapid upward motion and sometimes rotation. However, not all wall clouds rotate. If the wall cloud is seen rotating, the formation of a tornado is possible.

sounding - A sounding is the graphical output taken by a rawindsonde which is launched with a weather balloon to record various atmospheric variables in differing altitudes. Temperature, moisture, and wind speed/direction are most commonly measured when a sounding is taken. The data can be plotted on a diagram called a skew-t diagram which can give important details on the atmosphere such as how stable or unstable it is.

Diamond Dust - A type of precipitation composed of slowly falling and very small, ice crystals which often seem to float in the air. It may fall from a high cloud or from a cloudless sky. It only occurs during frigid temperatures. Diamond dust is observed around 316 days a year in parts of Antarctica.
