Amazing View of Convective Available Potential Energy (CAPE) Across The Planet! (credit: Earth)7/27/2016
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.

DISCUSSION: As strong to severe thunderstorms roared through coastal sections of New Jersey earlier this evening, there are unbelievably majestic storm structure observed. One such example is the storm structure observed in and around Lakewood, New Jersey (as well as areas to the north and south of there). Having said that, in the image below, you can clearly see a picture-perfect shelf cloud moving directly over the boardwalk adjacent to the beach and shoreline in parts of Central to Northern New Jersey. The feature in the image below is a classic shelf cloud which generally forms as a result of warm air being rapidly lifted over the leading edge of the cooler air rushing away from the leading portion of the approaching thunderstorm. Along with the presence of this gorgeous shelf cloud earlier this evening there was also impressive lightning on display in association with these severe thunderstorms which affected parts of coastal New Jersey!
