Sentences with phrase «scaling of precipitation extremes»

O'Gorman, P. A., and T. Schneider, 2009: Scaling of precipitation extremes over a wide range of climates simulated with an idealized GCM.

Not exact matches

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 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.

So: The study finds a fingerprint of anthropogenic influences on large scale increase in precipitation extremes, with remaining uncertainties — namely that there is still a possibility that the widespread increase in heavy precipitation could be due to an unusual event of natural variability.The intensification of extreme rainfall is expected with warming, and there is a clear physical mechanism for it, but it is never possible to completely separate a signal of external forcing from climate variability — the separation will always be statistical in nature.

Large - scale flooding can also occur due to extreme precipitation in the absence of snowmelt (for example, Rush Creek and the Root River, Minnesota, in August 2007 and multiple rivers in southern Minnesota in September 2010).84 These warm - season events are projected to increase in magnitude.

Its six chapters cover temperature assessment, precipitation assessment, large - scale climate variability modes and related oscillation indices, extreme events, climate and composition of the atmosphere and cryosphere and sea level.

Of the types of extremes that battered the country this year, only certain large - scale phenomena among them — such as heat waves, droughts and heavy precipitation — have links to climate changOf the types of extremes that battered the country this year, only certain large - scale phenomena among them — such as heat waves, droughts and heavy precipitation — have links to climate changof extremes that battered the country this year, only certain large - scale phenomena among them — such as heat waves, droughts and heavy precipitation — have links to climate change.

There is medium confidence that anthropogenic influences have contributed to intensification of extreme precipitation at the global scale.

In some locations, such extreme precipitation does not simply scale with the ability of the atmosphere to hold moisture (i.e. at the Clausius - Clapyron rate of 6 to 7 % per °C).

A set of long, nearly complete daily precipitation series for Alaska spanning the latter half of the 20th century has been analyzed for seasonal relationships between variations in mean, heavy, and extreme precipitation and large - scale atmospheric circulation variations at interannual, decadal, and secular timescales.

Further investigation using high - resolution modeling approaches that better resolve the boundary conditions and fine - scale physical processes (44 ⇓ — 46) and / or using analyses that focus on the underlying large - scale climate dynamics of individual extreme events (8) could help to overcome the limitations of simulated precipitation and temperature in the current generation of global climate models.

Recent work by Agel et al. provides a detailed regional analysis of the seasonal and spatial distribution, time - scale, and contributing large - scale factors associated with extreme short - term precipitation in the Northeast.

In summary, in contrast with the simulations of extreme temperature by climate models, extreme precipitation is difficult to reproduce, especially for the intensities and patterns of heavy rainfall which are heavily affected by the local scale (see Chapter 10).
