Drs Singer and Michaelides employ STORM to
show that the historical
rainfall trends likely resulted in less runoff from this dryland basin, an effect they expect to have occurred at many similar basins in the region.
Found one from the Aussie Govt clearly
showing the upward
rainfall trend.
Here we analyze a series of climate model experiments along with observational data to
show that the recent warming
trend in Atlantic sea surface temperature and the corresponding trans - basin displacements of the main atmospheric pressure centers were key drivers of the observed Walker circulation intensification, eastern Pacific cooling, North American
rainfall trends and western Pacific sea - level rise.
In contrast, the daily
rainfall variability during July - August
shows a statistically significant (5 per cent significance level) increasing
trend.
My point is simply that observations of the actual
rainfall trend in recent times are not consistent with CSIRO model projections (I will of course withdraw this comment if my figuring is
shown to be wrong).
Remarkably, the raw data
shows between ~ 1870s to 1940s Australia temperature
trends did NOT follow world
trends, largely as a result of changes in
rainfall.
One model
showed a 17 - percent increase in extreme
rainfall between 1861 and 2017 — quite similar to the
trend found in the actual
rainfall observations.
This view is unsupported, he says, by data for the past hundred years analyzed by the US National Climate Data Center that captures information on
rainfall, drought and other indicators and found that only the last few decades
showed signs of more extreme climate, not a long - term
trend.
Northern Australian wet season
rainfall (Jones et al., 2004), updated through 2004 — 2005 (Figure 3.36),
shows the positive
trend and the contribution of the anomalously wet period of the mid-1970s as well as the more recent anomalously wet period around 2000 (see also Smith, 2004).
And as far as precipitation goes, the
trends down there are all over the place — some stations
show trends towards increasing
rainfall amounts, while others nearby, towards decreasing amounts.
* «UK
rainfall shows large year to year variability, making
trends hard to detect» * «While connections can be made between climate change and dry seasons in some parts of the world, there is currently no clear evidence of such a link to recent dry periods in the UK» * «The attribution of these changes to anthropogenic global warming requires climate models of sufficient resolution to capture storms and their associated
rainfall.»
Some analyses of long - term historical weather data for the region
show a drying
trend, and others no change in
rainfall at all (Hulme et al. 2001; Christensen et al. 2007; Funk et al. 2008; Williams and Funk 2011).
