Extreme flood events have been and continue to be one of the most important natural hazards responsible for deaths and economic losses. Extreme floods result in direct destructive effects during the time of the event, and they also may be followed by a related chain of indirect calamities such as famines and epidemics that produce additional damages and suffering. Extreme hydrological events th...

The 781,000 km (193 million acre) United States National Forests and Grasslands system (NF) provides important ecosystem services such as clean water supply, timber production, wildlife habitat, and recreation opportunities to the American public. Quantifying the historical impacts of climate change and drought on ecosystem functions at the national scale is essential to develop sound forest ma...

At very high energy the same universal relation between the multiparticle or the transverse energy distribution associated to a rare event C, P C and the corresponding minimum bias distribution P, P C (ν) ≡ ν/ < ν > P (ν), ν ≡ n or E T works for nucleus-nucleus collisions as well as for hadron-hadron collisions. This suggests that asymptotically, all hadronic processes are similar.

In recent years, extreme weather events have led to ever larger economic losses in the United States. Multibillion dollar losses now occur with increasing frequency. The trend in losses has led many to conclude that the United States has witnessed changes in the frequency and/or intensity of extreme events. These perceptions are more than idle speculations— they underlie policy decisions with i...

The collapse of the roof of the Baltimore & Ohio (B&O) Railroad Museum Roundhouse onto its collections during a snowstorm in 2003 provides a starting point for our exploration of the link between learning and rare events. The collapse occurred as the museum was preparing for another rare event: the Fair of the Iron Horse, an event planned to celebrate the 175th anniversary of American railroadi...

*Correspondence: Ana C. Russo, Instituto Dom Luiz, Faculdade de Ciências, Universidade de Lisboa, Edifício C8, Piso 3, 1749-016 Lisboa, Portugal e-mail: [email protected] Europe has suffered several extreme weather events which were responsible for considerable ecological and economic losses in the last few decades. In Southern Europe, droughts are one of the most frequent extreme weather events...

The research focuses on identifying and characterizing the occurrence of episodes meteorological droughts in Puno region Perú, order to determine economic impact this climatic phenomenon agricultural activities region. From use standardized rainfall index for 12 months (SPI-12) period 1981-2019, occurrence, magnitude, persistence spatial evolution drought events area were determined, determinin...
