Aerosol Effects on Instability, Circulations, Clouds, and Precipitation

Figure 3

Schematic depiction of the atmosphere with a horizontal temperature gradient. The red column (W) has a higher temperature than the blue column (C). The arrows represent air motions. The arrow in the red column represents rising air and that in the blue column represents sinking air, while the arrows across the two columns represent convergence or divergence of air between them.
