Cloud Types: common cloud classifications

For example, cloud names containing the prefix "cirr-", as in cirrus clouds, are located at high levels while cloud names with the prefix "alto-", as in altostratus, are found at middle levels. This module introduces several cloud groups. The first three groups are identified based upon their height above the ground. List of cloud types. Clouds are formed in the Earth's atmosphere when water evaporates into vapor from oceans, lakes, ponds, and even streams and rivers; and by evaporation or transpiration over moist areas of Earth's land surface.[1] The vapor rises up into colder areas of the atmosphere due to convective, orographic, or frontal lifting.

This subjects the rising air to a process called adiabatic cooling.[2] The water vapor attaches itself to condensation nuclei which can be anything from dust to microscopic particles of salt and debris. Once the vapor has been cooled to saturation, the cloud becomes visible. All weather-producing clouds form in the troposphere, the lowest major layer of the atmosphere. However very small amounts of water vapor can be found higher up in the stratosphere and mesosphere and may condense into very thin clouds if the air temperatures are sufficiently cold.

The nephology branch of meteorology is focused on the study of cloud physics. Extremely high cirriform[edit] Type 1 Type 2.

Tracking marine debris from Japanese tsunami. Video: Tsunami Aftermath: Marine Debris | Download: 1280 x 720 (70 MB) Ongoing efforts to update and refine computer models with wind speed and ocean current data is leading to a better understanding of how fast tsunami-generated debris may travel across the Pacific.

Visit NOAA's Marine Debris Program for the latest information and modeling maps. Audio Podcast: The powerful Japanese earthquake and resulting tsunami in March, 2011, washed untold tons of marine debris into the Pacific Ocean. Carey Morishige, Pacific Islands Regional Coordinator for the NOAA Marine Debris Program, explains where this debris may be, where it's heading, what's being done about it, and what you can do to help. Debris from the tsunami that devastated Japan in March 2011 could continue washing ashore in the United States for many years, according to predictions by NOAA scientists. Federal Agencies Join Forces As the tsunami surge receded, it washed much of what was in the coastal inundation zone into the ocean. Japanese tsunami debris link roundup. Estimation of debris path created with OSCURS model.

Debris from the 2011 Japanese tsunami is headed towards Hawaii and the North American west coast. Explainers: NOAA has a new video and podcast explaining how the debris is moving across the ocean, and what you can do to help.
