Former Director of the Central Weather Bureau, Cheng Mingdian, explained on Facebook the phenomenon of cold core low pressure, which is usually difficult to see without accompanying cloud systems. This high-level weather phenomenon is known to increase instability and intensify thunderstorms when it moves in. The Central Weather Bureau further elaborated that cold core low pressure, mainly found in the upper atmosphere during summer and autumn, is not visible on conventional surface weather maps but can be detected using high-altitude water vapor channel cloud maps. Despite being present only at high altitudes, cold core low pressure can influence local weather by lowering temperatures aloft and enhancing convection, leading to more severe thunderstorms and potentially triggering phenomena like tropical depressions or typhoons.
