Lenticular clouds - The scientific name is altocumulus standing lenticular clouds. These lens shaped clouds are the most common cloud type to be mistaken for UFO's. They are most common near mountain ranges, as they form when strong winds blow up and over the top of a mountain range. Even though the winds within these clouds are moving very quickly, the cloud formation itself remains stationary. The presence of a lenticular cloud signifies an area of severe turbulence in the atmosphere, as pilots avoid them when possible.

Tropical Depression - A tropical cyclone with sustained winds lower than 30 knots/35 mph/55kph. The main impacts from a tropical depression would be heavy rain, gusty winds, and a modest storm surge where they make landfall.

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

Corona - A corona is a series of alternating dark and bright rings of light that can at times be seen surrounding the moon or sun. When a thin stratus cloud is present, a corona can be seen around the moon as the moonlight is diffracted by the water droplets in the cloud. The corona of the sun is most visible during a total solar eclipse.

Blizzard Warning - Blizzard Warnings are issued when visibilities are reduced to a quarter mile or less for 3 hours or longer. Wind speeds must also be sustained at 35 mph with frequent higher gusts in order to achieve blizzard conditions.

Transpiration - The process by which water escapes plants into the air and turns into water vapor. The rate at which plants lose water to the air increases as the temperature increases. Corn plants transpire at a rate higher than most plants. This means that corn needs more moisture to survive compared to most plant life.

Aurora Borealis - Also known as the northern lights; these luminous radiant emissions from the upper atmosphere can be seen over middle and high latitudes. They are centered around the earth's magnetic poles. These silent fireworks are often seen on clear winter nights in a variety of shapes and colors.
