Not exact matches

A new report released Friday by the National Academy of Sciences has found that such extreme event attribution studies can be done reliably for certain types of weather extremes, including heavy precipitation.

This is addressed by evaluating change in global or large - scale patterns in the frequency or intensity of extremes (e.g., observed widespread intensification of precipitation extremes attributed to human influence, increase in frequency and intensity of hot extremes) and by event attribution methods.

In the second real - time extreme weather attribution study in the context of the World Weather Attribution project the team found a 5 - 80 % increase in the likelihood of heavy precipitation like those associated with storm Desmond to occur due to anthropogenic climattribution study in the context of the World Weather Attribution project the team found a 5 - 80 % increase in the likelihood of heavy precipitation like those associated with storm Desmond to occur due to anthropogenic climAttribution project the team found a 5 - 80 % increase in the likelihood of heavy precipitation like those associated with storm Desmond to occur due to anthropogenic climate change.

My experience with extremes and detection and attribution of an anthropogenic signal in those is that only by averaging the behavior of extremes (both temperature extremes and precipitation extremes) over large geographical areas (continental or barely sub-continental) we have been able to see something outside of natural variability.

There have also been some reports on trends of more extreme precipitation, although The International Ad Hoc Detection and Attribution Group (IDAG, 2005) did not manage to attribute trends in precipitation to anthropogenic greenhouse gases (G)-- a quote from their review article is: «For diurnal temperature range (DTR) and precipitation, detection is not achieved», here «detection» implying the signal of G.

In fact, Min et al. used leading empirical orthogonal functions (EOFs; a type of principal component analysis) in their attribution analysis for extreme precipitation, implying large spatial scales.

«Since the AR4, there is some new limited direct evidence for an anthropogenic influence on extreme precipitation, including a formal detection and attribution study and indirect evidence that extreme precipitation would be expected to have increased given the evidence of anthropogenic influence on various aspects of the global hydrological cycle and high confidence that the intensity of extreme precipitation events will increase with warming, at a rate well exceeding that of the mean precipitation..

Topics include observations of precipitation extremes, detection and attribution work on precipitation extremes and projected changes to precipitation extremes.

2012 Controversial «attribution» studies find recent disastrous heat waves, droughts, extremes of precipitation, and floods were made worse by global warming.
