Cloud Street - Clouds that are aligned in rows that are parallel to the direction of the wind. Cloud streets are oftentimes composed of cumulus clouds.

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.

El Nino - An anomalous warming of ocean waters in the east central equatorial Pacific. El Nino events occur every two to seven years and have local as well as global impacts. Nutrient deficient waters cripple the fishing industry off the coast of western South America during El Ninos, while global weather patterns can be significantly altered due to the presence of an El Nino.

Condensation funnel - A condensation funnel is composed of water droplets and rotates while it extends down from the base of the thunderstorm. When it reaches the ground, it is called a tornado. If it stays above the ground, it remains a funnel cloud.

Noctilucent Clouds - These are a type of cloud that is extremely rare and found very high in the atmosphere. The base of these clouds is typically around 200,000 feet. They are seen as wavy, thin, bluish-white clouds and are best seen at twilight in polar latitudes. The word Noctilucent is derived from the latin word that means "night-shining.'

Cirrostratus clouds - A widespread, thin high level cloud that is composed of ice crystals. These clouds form a thin veil-like layer over the entire sky. When sunlight or moonlight passes through these clouds, a ring or halo may form. Many times cirrostratus clouds arrive 12-24 hours before a rain or snow event.

Mountain Breeze - A wind pattern that develops during the night due to differential cooling on the mountain compared to nearby valleys. The mountain cools faster than the valleys in the evening. This cool, dense air blows down the mountainsides into the valleys. The opposite occurs during the day, which produces an upslope wind known as the valley breeze.
