The above map looks at what is known as ceilings. The definition of ceilings is the first broken or overcast layer of cloud cover in the atmosphere. For it to be considered a ceiling the clouds need to cover more than half of the sky. If we look at the red circled area we see the numbers of 1 and 2. This tells us that there is a ceiling at 1,000-2,000ft which are in the level of low clouds such...

Cumulus-nimbus Clouds

The image above shows a Cumulus-nimbus cloud that has an anvil top to it. The reason that can be identified is that the cirrus is in place above the center of the storm. The image below does not have an anvil top yet. The anvil top forms on CB clouds after they reach the height in the atmosphere where they begin to feel the upper level winds becoming too strong for them to continue development...

Cumulus Clouds Low Cloud

If you look in the photo above you can see the line of Cumulus clouds that appear in the background. These clouds were created by daytime heating and also an unstable atmosphere. The moisture for these clouds was rising from the Pacific Ocean. The darker cloud is the stronger of the cumulus clouds meaning that the majority of the moisture is being absorbed by that cloud. The clouds around this...

Cumulus clouds are white in appearance and are formed when warm moist air near the earth’s surface is forced aloft by day time heating. Cumulus clouds are usually associated with nice weather, however if they continue to grow and get more moisture and instability with them they can turn into Towering Cumulus and CB clouds which would change the weather to increase the chance of seeing...

Cirrocumulus

Cirrocumulus clouds are high-altitude clouds that mainly occur between 16,000 and 40,000 feet. Like most cumulus clouds, these clouds indicate a vertical and upward transference of atmospheric conditions. Unlike other cirrus clouds, cirrocumulus composition includes super-cooled liquid water droplets. Ice crystals are also present, and usually, the ice crystals cause the droplets in the cloud...

Word of the Day
bretelles
  • In dressmaking, straps running from the belt in front over the shoulders to the belt in the back, with more or less elaboration of trimming and outline. They usually broaden at the shoulder and narrow toward the waist.
