Climate Change: Causes & Impacts (SL IB Environmental Systems & Societies (ESS))

Weather and climate are significantly influenced by atmospheric circulatory systems, which result in the movement of air masses, distribution of heat, and the formation of weather patterns.

Air movement within atmospheric pressure cells is roughly circular and moves surplus heat from equatorial regions to other parts of the Earth.

In both hemispheres, heat energy transfer occurs where three atmospheric circulation cells meet.

State the names of these three cells that make up the tricellular model of atmospheric circulation.

State two sources of methane emissions.

Climate change can amplify or intensify changes, leading to further global warming

For example, increasing temperatures result in the release of the potent greenhouse gas methane from thawing permafrost, which further enhances the greenhouse effect.

Identify the name of this type of process.
