Cloud Types

• This script has been adapted from Bashewa's original Ver 2.1 script.
• The Original was for WD, Virtual Weather Station and WUHU.)
• Cloudbase CU Script
• It has now been adapted to work with Meteobridge.
• No Metar image is from the Weather Station Data
• Metar Data is from EGAC - Belfast Approx 8.2 miles away
• Data comparison may vary slightly due to altitude of WX

High Level Clouds

• Cirrus are high clouds which are composed of ice cystrals that originate from the freezing of supercooled water droplets.
• They are thin and have a wispy appearance, and are often transparent.
• Usually indicates a change in weather will occur within 24 hours.

• Cirrostratus are high clouds, composed of ice crystals.
• Appear as small individual cloudlets in rows. No shading can be seen on the lower surface.
• Usually indicate fair weather for the near future.

• Cirrostratus are high clouds, composed of Ice Crystals.
• Thin and uniform appearance, Often covering the whole sky. A halo of the sun or moon can usually be seen through the cloud.
• Usually indicate rain or snow within the next 12 - 24 hours.

Mid Level Clouds

• Altocumulus are Mid level clouds composed of water droplets.
• Similar to Cirrocumulus, but have larger individual cloudlets, and shading can be seen.
• If seen in the morning, prepare for a thunderstorm in the afternoon.

• Altostratus clouds are mid level clouds composed of ice crystals and water droplets.
• Generally uniform and grey in appearance, and frequently cover the entire sky. The sun or moon may also be seen through them, but is usually quite fuzzy.
• Tend to indicate a storm some time in the very near future.

Low Level Clouds

• Stratocumulus clouds are low level clouds composed of water droplets
• Appear as low patches or sheets of grey to white cloud, with individual rolls or rounded masses.
• Do not usually bring precipitation.

• Stratus clouds are low level clouds composed of water droplets.
• Appear as a uniform greyish layer and often cover the entire sky. They can sometimes cover hill tops.
• Often bring drizzle or light snow.

• Nimbostratus clouds are low level clouds that might consist entirely of cloud droplets or raindrops, or of ice crystals and snowflakes.
• They are thick grey clouds with a ragged base. Sometimes they cover the entire sky.
• Indicate rain in the very near future.

• Cumulus clouds are low level clouds, composed of water droplets.
• They are have a puffy appearence, a flat base and are white or light grey.
• Indicate fair weather unless they grow vertically.

Vertically Developed Clouds

• Cumulonimbus clouds are Vertically Developed Clouds which are composed of water droplets and ice crystals.
• Appear dark and very tall often extending through all the levels of altitude, and can be several miles wide. They often appear in a shape similar to a mushroom.
• Usually indicate a storm in the near future. Rain, hail, thunder, lightning.

Other Clouds

• Contrails are visible trails of condensed water vapour made by the exhaust of aircraft engines.
