Mechanizmy of Heat Wave Formation in Arid Environments

Head waves are generally defined as prolonged period of excessively hot weathern, often akompaniad by high humidity or, in dry regions, by exceptionally low humidity and d intensie solar radiation.

However, thee underlying physical topography modifies each of these factors in signitant ways. The shape and orientation of thee land surface influence how solar energiy is absorbed, how air moves across thee landscape, and how haw heat acculates overnight. In essence, the Outback 's topography acts as both a maglupfier and a trap for heat, conting a regional weatheathern plant into locazized extremes that can aid 5o ° C (122 ° F) in some locations during events.
