DISCUSSION: Across the atmospheric science world, many scientists evaluate the degree of instability throughout the atmosphere by way of analyzing a parameter known as convective available potential energy (CAPE). CAPE essentially helps atmospheric scientists to assess the amount of instability present within the depth of the atmosphere at any given point in time. To no surprise, as seen in the graphic below, the greatest atmospheric instability appears to be confined to within the tropical regions of the planet (i.e., approximately within 10°N and 10°S). This agrees with fundamental meteorological theory based on this part of the Earth being collocated with the positioning of the inter-tropical convergence zone (ITCZ) which is a relatively narrow band of quasi-constant convection which circumnavigates the planet throughout the year.
