Open ocean convection is a process in which the mesoscale ocean ... the constant of proportionality γ and β are found to be equal to 3.9 ± 0.9 and 12 ± 3 ...
It is the first known work that attempts to treat a broad range of meteorological topics. [3] For the first time, precipitation and the clouds from which precipitation falls are called meteors, which originate from the Greek word meteoros, meaning 'high in the sky'. From that word comes the modern term meteorology, the study of clouds and weather.
In fluid dynamics, convective mixing is the vertical transport of a fluid and its properties. In many important ocean and atmospheric phenomena, convection is driven by density differences in the fluid, e.g. the sinking of cold, dense water in polar regions of the world's oceans; and the rising of warm, less-dense air during the formation of cumulonimbus clouds and hurricanes.
Scientists believe they’ve discovered an ancient ocean floor comprising a new layer between Earth’s mantle and core.
This was sufficient to allow computing of spreading rates over the last 700,000 years on many mid-ocean ridges by locating the closest reversed crust boundary to the crest of a mid-ocean ridge. [11] Marine magnetic anomalies were found later to span the vast flanks of the ridges. [ 9 ]
Convection is often categorised or described by the main effect causing the convective flow; for example, thermal convection. Convection cannot take place in most solids because neither bulk current flows nor significant diffusion of matter can take place. Granular convection is a similar phenomenon in granular material instead of fluids.

Atmospheric convection is the vertical transport of heat and moisture in the atmosphere.It occurs when warmer, less dense air rises, while cooler, denser air sinks. This process is driven by parcel-environment instability, meaning that a "parcel" of air is warmer and less dense than the surrounding environment at the same altitude.
