This implies that the mass of the maximum loss of the atmosphere occurs at a certain atmospheric pressure, at which the pressure dependence changes.
At the same time, inward diffusion of oxygen from the atmosphere occurred.
Though some mercury in the atmosphere occurs naturally, roughly two-thirds is produced by industrial sources — especially coal-burning power plants.
The removal of submicron aerosols from the atmosphere occurs by precipitation scavenging and by direct capture of the aerosols by landscape.
In the opposite case, when buoyancy is neglected, we have acoustic waves in air, and radiation into the atmosphere occurs when the phase speed c of surface waves exceeds the sound speed (Brekhovskikh and Godin 1998).
Many species in the FT, such as O3, have longer lifetimes than those in the PBL owing to the lower temperatures and lack of deposition in the FT, which is also where most of the transport of chemical species within the atmosphere occurs.
In other words, net C loss to the atmosphere occurs in instances where the disturbance interval is shorter than the time required for the forest to regrow to its pre-disturbance state, or where the forest experiences a permanent conversion to a different vegetation type.
They are the highest clouds in the Earth's atmosphere, occurring in the mesosphere at altitudes of around 76 to 85 kilometers (47 to 53 mi).
Evaporation into the open atmosphere occurs at the surface of the soil, and the soil dries progressively downward with time.
Solar flares — very intense brightenings of the sun's atmosphere — occur throughout the sun's 11-year activity cycle, with their frequency increasing as the cycle peaks, as it did around the 2012 event.
