Heatwave forcings

Forcings constructed along morasses

In a previous paper [11], we introduced a way of constructing a forcing along a simplified (κ, 1)-morass such that the forcing satisfies a chain condition. The basic idea is to generalize iterated forcing with finite support as introduced by Solovay and Tennenbaum, which works with continuous, commutative systems of complete embeddings. However, instead of considering a linear system of embeddi...

Short Extenders Forcings II

A model with otp(pcf(a)) = ω1 + 1 is constructed, for countable set a of regular cardinals. 1 Preliminary Settings Let 〈κα | α < ω1〉 be an an increasing continuous sequence of singular cardinals of cofinality ω so that for each α < ω1, if α = 0 or α is a successor ordinal, then κα is a limit of an increasing sequence 〈κα,n | n < ω〉 of cardinals such that (1) κα,n is strong up to a 2-Mahlo cardi...

The Excess Heat Factor: A Metric for Heatwave Intensity and Its Use in Classifying Heatwave Severity

Heatwaves represent a significant natural hazard in Australia, arguably more hazardous to human life than bushfires, tropical cyclones and floods. In the 2008/2009 summer, for example, many more lives were lost to heatwaves than to that summer's bushfires which were among the worst in the history of the Australian nation. For many years, these other forms of natural disaster have received much ...
