It's Hot ! Damn Hot !

This latest heatwave (in part triggering the huge fish kill in the Darling River) , and the one to follow next week, were caused by "blocking highs" in the Tasman Sea, allowing air to just sit in the centre of the country (largely rock and desert) and along with clear skies allowed the heat of mid summer solar radiation to just accumulate.
I don't know if these weather system phenomena are predicted by models (or linked to the deep ocean conveyor) -- but I'm sure one can be made to fit
The country posted it's highest ever overnight minimum temperature of 35.9°C (up by 0.4°C) , however the highest ever recorded daytime temperature is still the 50.7°C set way back in 1960.
Marble Bar (in WA) also posted 160 days in a row over 1923/1924 of over 37.9°C (100°F in the old money) ...... how people survived that I have no idea. No hypothesized "AGW" effects back then.

I wonder what effect the large areas of land clearing and open cut mining, and widespread hydrological functioning disruption (capture of overland flows, degradation /destruction of wetlands, and the soil sponge, and intersection and draining of natural aquifers, etc) is having on the tendency of the country to store increasing heat) ........ ?? :cat:
This phenomenon is studied and understood in urban /suburban environments (Urban Heat Islands become Urban Heat Continents:
https://www.news.com.au/technology/...t/news-story/0df25ff17daedbb5793b20da70968671 ), but if the broader landscape effect is studied in the scientific realms it is certainly not making it onto the mainstream media radar.
Nor is the contribution to the Great Barrier Reef die back events caused by excess fertilizer /nutrients, and sediment run off from cleared agricultural lands.
Seems like these are all "fertile" areas for scientific enquiry ......
Oh, and the biggest mystery around the incidence of Bushfires (or Brush or Wildfires as they are called stateside) is ...... which idiot started them ?! :storm: coz sure as heck the vast majority are NOT started by lightning ........
Chosun :gh:
