These changes aloft force changes below in the troposphere.
Strengthening storm systems within the troposphere can act to intensify the polar vortex by significantly cooling the poles.
Surface anticyclones form due to downward motion through the troposphere, the atmospheric layer where weather occurs.
The fragments were displaced in the lower atmosphere (troposphere) from their expected trajectories by strong wind.
The retreat and thinning is attributed to a decrease in precipitations and a warming of the upper troposphere over the last decades.
These rising air currents diverge in the upper troposphere and move away from the equator at high altitude in both northerly and southerly directions.
A change in the current density and in the initial values of electrical power delivered to the simulated troposphere resulted in differences in the type and amount of compounds formed.
Higher levels of pollutants in the lower troposphere may stimulate seed germination when other external conditions are inappropriate for seedling growth.
