Seiches - Standing waves that oscillate back and forth over an open body of water. They are most common in large bodies of water such as bays or lakes. The impetus for a seiche to occur is persistent strong winds that push water from one end of the body of water to the other. When the winds let up, the water that has been pushed to one side of the bay or lake starts to oscillate to the opposite shore and then back again. Anyone who sloshes water from one side of a bathtub to the other side has witnessed a small-scale seiche. The Great Lakes occasionally see seiche events that are noted by a rhythmic rise and fall of water levels.

Stratocumulus - These are low-level clouds that are seen as a relatively flat layer with some individual elements. Elements often are arranged in rows, bands, or waves. Stratocumulus clouds can reveal the depth of the moist air at low levels, while the speed of the cloud elements can reveal the strength of the winds along the low-level jet. Stratocumulous clouds are one of the most common types of clouds seen on Earth.

Scintillation - The apparent twinkling of a star due to its light passing through regions of differing air densities in the atmosphere. This results in the light being refracted and scattered before it reaches the viewer.

Advection Fog - Advection fog often looks like radiation fog and is also the result of condensation. However, the condensation in this case is caused not by a reduction in surface temperature, but rather by the horizontal movement of warm moist air over a cold surface. This is very common during the winter when warm moist winds blow over cold snowcover. Advection fog may also form when moist maritime air masses drift over a cold inland area. This usually happens at night when the temperature of the land drops due to radiational cooling.

Pluie - This is the french word for rain. To say, "it is raining today" one would say, "Il pleut aujourd'hui."

Verglas - Taken from the French language, this is a term that is used to describe a thin coating of ice that forms on an object, such as a rock.
