A screenshot taken on 1 March 2022, by a concerned citizen, shows that the official BOM rain gauge in the centre of Lismore registered 467 mm on 28th February 2022, breaking the previous record of 334.3 mm set in 1954. There was no recording from the rainfall gauge at Lismore Airport bec...
2019). Furthermore, Yildirim and Rahman (2021) found maximum drought quantities (the longest duration, biggest magnitude, and highest intensity) of short- and long-term droughts in various rainfall districts in southeastern Australia between 2013 and 2019. It can be concluded that the study area ...
Data were obtained from the Australian Bureau of Meteorology (BoM) from 136 high-quality weather stations. To reduce spatial complexity, climate regionalization was used to divide the stations in homogenous sub-regions based on similarity of rainfall patterns and intensity using principal component ...
In any case on the minor AGW point – one of BoM’s known previous statistical system issues was the warming trend (oh dear) in the Indian Ocean. You could of course have tried the Oodnadatta Index and found the sub-tropical ridge intensity was also trending (double oh dear). I’ve no...
Globally, the intensity and frequency of droughts and rainfall extremes are projected to increase due to anthropogenic climate change8,9. However, detecting the human influence on drought at regional scales is challenging, with clear climate change signals emerging in only selected regions (e.g., ...
However, the recovery of such vegetation is dependent on factors such as the intensity and duration of grazing and the availability of soil moisture and nutrients (Leriche et al., 2003). In our grazed plots, however, grazing and reduction in rainfall induced both biotic and abiotic stresses ...
Other predictors especially if you’re going national – sub-tropical ridge (STR) latitude and STR intensity, the 6 major SST grid boxes around the nation, SAM, MJO. And phew – have you thought about doing streamflow? Anyway don’t mind me – just thought you’d like some serious feed...
Climate change is manifesting through increased intensity and frequency of extreme events such as droughts and floods. Drought causes significant stress by limiting water availability, resulting in reduced plant growth and belowground carbon (C) inputs as well as plant nutrient uptake and microbial acti...
Australia has been exposed to a vast array of extreme weather regimes over the past few years, and the frequency and intensity of these events are expected to increase as a result of anthropogenic climate change. However, the predictability of extreme droughts, heat waves (HWs), bushfires and...
This paper builds on the work of Rahman et al (2002a) in developing Intensity Frequency Duration (IFD) tables that are used as the basis of rainfall event generation in the Monte Carlo simulation. The current approach as outlined by Rahman et al (2002a) involves identification of 'core' ...
