Better predicting how plants and animals will weather climate extremes
ecomechanical models extreme climate plants animals
2021/8/4
A team of scientists has devised a more accurate way to predict the effects of climate change on plants and animals -- and whether some will survive at all.
Extremes—Oceanography's Adventures at the Poles
Extremes Oceanography's Adventures the Poles
2015/7/22
Extremes is a collection of papers from the fourth Maury Workshop on the history of oceanography, held in Barrow, Alaska. From the editors' notes, and comments in the introduction by Michael Reidy, th...
By now, most sci-en-tists—97 per-cent of them, to be exact—agree that the tem-per-a-ture of the planet is rising and that the increase is due to human activ-i-ties such as fossil fuel use and defor-es...
Max-stable models for multivariate extremes
Copula domain of attraction max-stable distribution spectral measure tail dependence
2012/4/17
Multivariate extreme-value analysis is concerned with the extremes in a multivariate random sample, that is, points of which at least some components have exceptionally large values. Mathematical theo...
Tail Asymptotic of Sum and Product of Random Variables with Applications in the Theory of Extremes of Conditionally Gaussian Processes
tail asymptotic Laplace method self-similar processes Gaussian processes locally stationary processes
2011/9/15
Abstract: We consider two independent random variables with the given tail asymptotic (e.g. power or exponential). We find tail asymptotic for their sum and product. This is done by some cumbersome bu...
Temperature extremes in the Mediterranean area: trends in the past and assessments for the future
Temperature extremes the Mediterranean area trends the past and assessments the future
2010/10/21
Trends of Mediterranean extreme temperatures are analysed for the period 1961–1990 based on daily station time series. Increases can be identified in the western Mediterranean area, whereas an opposit...
Geo-effectiveness of Solar Wind Extremes
Geomagnetic storms geomagnetic activity solar wind streams interplanetary magnetic field space weather
2010/9/16
Examples of extreme events of solar wind and their effect on geomagnetic conditions are discussed here. It is found that there are two regimes of high speed solar wind streams with a threshold ofͬ...
Subsampling weakly dependent times series and application to extremes
dependent times series extremes
2010/11/30
This paper provides extensions of the work on subsampling by Bertail et al. (2004) for strongly
mixing case to weakly dependent case by application of the results of Doukhan and Louhichi (1999).We in...
Seasonal sea level extremes in the Mediterranean Sea and at the Atlantic European coasts
Seasonal sea level the Mediterranean Sea at the Atlantic European coasts
2010/10/21
Hourly sea level data from tide gauges and a barotropic model are used to explore the spatial and temporal variability of sea level extremes in the Mediterranean Sea and the Atlantic coasts of the Ibe...
Indices of precipitation extremes in Southern Portugal–a geostatistical approach
precipitation extremes Southern Portugal geostatistical approach
2009/12/16
Most of the actual studies and previews of future rainfall patterns, based on past observed records for Mediterranean climate areas, focus on the decline of the rainfall amounts over the years, and al...
An analysis of the evolution of hydrometeorological extremes in newspapers:the case of Catalonia,1982–2006
evolution hydrometeorological extremes newspapers case of Catalonia
2009/12/8
This contribution analyzes the evolution of perception of certain natural hazards over the past 25 years in a Mediterranean region. Articles from newspapers have been used as indicator. To this end a ...

A delay differential model of ENSO variability:parametric instability and the distribution of extremes
delay differential model ENSO variability parametric instability distribution of extremes
2009/10/30
We consider a delay differential equation (DDE) model for El-Niño Southern Oscillation (ENSO) variability. The model combines two key mechanisms that participate in ENSO dynamics: delayed negat...
Frequency of Extremes and its Relation to Climate Fluctuations
Frequency of Extremes Climate Fluctuations
2009/10/26
Possible consequences of climate change concern both changes in long-term
mean values of runoff and changes in frequency and magnitude of extreme
runoff events. The physical safety of dams and prote...
Probability Distribution of Precipitation Extremes over the Yangtze River Basin
precipitation extremes ECHAM5 model probability distribution model Yangtze River basin
2009/8/28
Based on the daily observational precipitation data of 147 stations in the Yangtze River basin for 1960-2005, and the projected daily data of 79 grids from ECHAM5/MPI-OM in the 20th century, time seri...
