Visualization of a (fictive) formation of isotherms (red-orange) and isobars (blue) in a baroclinic atmospheric layering. A rotating tank experiment modelling baroclinic eddies in the atmosphere In fluid dynamics , the baroclinity (often called baroclinicity ) of a stratified fluid is a measure of how misaligned the gradient of pressure is from ...
Within the Earth's atmosphere and surface, the liquid phase is the most common and is the form that is generally denoted by the word "water". The solid phase of water is known as ice and commonly takes the structure of hard, amalgamated crystals, such as ice cubes, or loosely accumulated granular crystals, like snow.
Water vapor thus has a scale height a fraction of that of the bulk atmosphere, [21] [22] [23] as the water condenses and exits, primarily in the troposphere, the lowest layer of the atmosphere. [24] Carbon dioxide ( CO 2 ) and methane , being well-mixed in the atmosphere, tend to rise above water vapour.
Water vapor concentration for this gas mixture is 0.4%. Water vapor is a greenhouse gas in the Earth's atmosphere, responsible for 70% of the known absorption of incoming sunlight, particularly in the infrared region, and about 60% of the atmospheric absorption of thermal radiation by the Earth known as the greenhouse effect.

Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
The colour blood red is a dark shade of the colour red meant to resemble the colour of human blood (which is composed of oxygenated red erythrocytes, white leukocytes, and yellow blood plasma). [2] It is the iron in hemoglobin specifically that gives blood its red colour. The actual colour ranges from crimson to a dark brown-blood depending on ...
The Kelvin–Helmholtz instability can be seen in the bands in planetary atmospheres such as Saturn and Jupiter, for example in the giant red spot vortex. In the atmosphere surrounding the giant red spot there is the biggest example of KHI that is known of and is caused by the shear force at the interface of the different layers of Jupiter's ...
To create ice XVII, the researchers first produced filled ice in a stable phase named C 0 from a mixture of hydrogen (H 2) and water (H 2 O), using temperatures from 100 to 270 K (−173 to −3 °C; −280 to 26 °F) and pressures from 360 to 700 MPa (52,000 to 102,000 psi; 3,600 to 6,900 atm), and C 2 are all stable solid phases of a mixture ...
