Projection of Future Precipitation Extremes Change (2001-2050) in the Yangtze River Basin
Yangtze River basin extreme precipitation daily maximum rainfall the year 2050 projection
2009/8/28
Daily maximum rainfall (R1D) was higher in the Jialing River basin, the Taihu Lake area and the mid-lower main stream section of the Yangtze River basin in the 1990s, and there was a good relationship...
Ongoing global warming and local warm extremes: a case study of winter 2006-2007 in Helsinki, Finland
climate change temperature extreme Finland CMIP3
2009/6/9
December 2006 and March 2007 were both record warm in large parts of northern Europe. Here
we focus on temperatures observed in Helsinki, Finland, and study whether these mild winter months can be in...
Relationships between statistics of rainfall extremes and mean annual precipitation：an application for design-storm estimation in northern central Italy
mean annual precipitation rainfall extremes
2009/5/13
Several hydrological analyses need to be founded on a reliable estimate of the design storm, which is the expected rainfall depth corresponding to a given duration and probability of occurrence, usual...
Geo-effectiveness of Solar Wind Extremes
Geomagnetic storms geomagnetic activity solar wind streams interplanetary magnetic field space weather
2009/5/7
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 of ...
Effects of decreasing acid deposition and climate change on acid extremes in an upland stream
climate change upland stream acid deposition
2009/4/29
This study assesses the major chemical processes leading to acid extremes in a small, moorland stream in mid-Wales, UK, which has been monitored since 1979. Results suggest that base cation (mainly ca...
Optical closure in lakes with contrasting extremes of reflectance
Optical closure contrasting extremes
2014/4/21
We measured inherent and apparent optical properties and computed ‘optical closure’ in four lakes on the South
Island of New Zealand, ranging very widely in reflectance. Optical properties were measu...
Nitrogen dynamics in runoff from two small heathland catchments representing opposite extremes with respect to climate and N deposition in Norway
catchments surface water nitrogen deposition
2009/3/17
Effects of contrasting climatic conditions and nitrogen (N) deposition levels on streamwater N dynamics are assessed at two small heathland catchments; Dalelva in northern Norway (69°N) and Øyg...
On the variability of return periods of European winter precipitation extremes over the last three centuries
European winter precipitation extremes three centuries
2008/11/4
We investigate the changes of extreme European winter (December-February) precipitation back to 1700 and show for various European regions that return periods of extremely wet and dry winters are subj...
The impact of an upper tropospheric teleconnection pattern on precipitation extremes over Cyprus

2010/1/27
Analysis of extreme hydrometeorological events is important for characterizing and better understanding the meteorological conditions that can generate severe rainstorms and the consequent catastrophi...
Extreme heat and runoff extremes in the Swiss Alps
Extreme heat runoff extremes Swiss Alps
2009/12/30
The hydrological response of Swiss river basins to the 2003 European summer heatwave was evaluated by a combined analysis of historical discharge records and specific applications of distributed hydro...
L-moments based assessment of a mixture model for frequency analysis of rainfall extremes
