Changes in wind regimes, sea surface temperature and wind speeds. High-wind conditions that may exceed a building’s design specifications.
The Climate Risk Engines extreme wind model draw from two types of extreme wind; (1) synoptic wind and, (2) convective wind. Both are modelled under extreme wind, though they have different drivers for baseline hazard data and climate projection data. Tropical Cyclone wind damage is modelled and reported as a separate hazard.
Synoptic
Synoptic winds are driven by pressure gradients between large-scale atmospheric pressure systems (on the order of hundreds of kilometres, e.g. low pressure systems) that are the result of temperature differences across the Earth.
Convective
Convection, the processes that produce thunderstorms, poses numerous threats to individuals and property including damaging straight-line winds, large hail, heavy rainfall, lightning and tornadoes.
Convective Available Potential Energy (CAPE) and wind shear (bulk wind difference) between the Surface and 6 km (S06) are considered the most influential environmental attributes for the formation and development of severe convection that is capable of producing damage
