夏季亚洲-太平洋热力差异年代-百年尺度变化与太阳活动
亚洲-太平洋涛动 年代-百年尺度变率 太阳活动 突变
2013/8/28
利用重建的近千年亚洲-太平洋涛动指数和太阳辐照度时间序列, 用统计方法研究了夏季亚洲与其周边的海陆热力差异在年代-百年际时间尺度上的变化特征及其与太阳辐照度的关系, 结果表明: 亚洲季风区热力差异存在着90 a 左右、10~13 和3~7 a 的周期振荡; 在百年尺度上, 热力差异表现出3 次明显突变, 它们分别发生在1305~1315 年、1420~1430 年以及1625~1635 年. 海陆...

Verification new ECMWF ERA-Interim France
2011/3/15
An evaluation of the global ECMWF atmospheric reanalysis ERA-Interim (with a 0.5° grid) is performed over France, based on the high resolution (8 km) SAFRAN atmospheric reanalysis. The ERA-Interim pre...
Uncertainty in climate change impacts on water resources in the Rio Grande Basin, Brazil
Uncertainty in climate water resources Rio Grande Basin
2011/3/15
We quantify uncertainty in the impacts of climate change on the discharge of Rio Grande, a major tributary of the Paraná River in South America and one of the most important basins in Brazil for water...
Spatial interpolation of hourly rainfall – effect of additional information, variogram inference and storm properties
Spatial interpolation hourly rainfall additional information variogram inference
2011/3/15
Hydrological modelling of floods relies on precipitation data with a high resolution in space and time. A reliable spatial representation of short time step rainfall is often difficult to achieve due ...

Reliability robustness rainfall compound weather pattern sub-sampling
2011/3/14
A new probabilistic model for daily rainfall, named MEWP (Multi Exponential Weather Pattern) distribution, has been introduced in Garavaglia et al. (2010). This model provides estimates of extreme rai...

This paper describes the evaluation of the KNMI Cloud Physical Properties – Precipitation Properties (CPP-PP) algorithm over West Africa. The algorithm combines condensed water path (CWP), cloud phase...
A multiple threshold method for fitting the generalized Pareto distribution to rainfall time series
generalized Pareto distribution rainfall time series
2010/12/22
Previous studies indicate the generalized Pareto distribution (GPD) as a suitable distribution function to reliably describe the exceedances of daily rainfall records above a proper optimum threshold,...
Streamflow sensitivity to climate and land cover changes: Meki River, Ethiopia
climate land cover changes
2010/12/22
Impacts of climate and land cover changes on streamflow were assessed using a hydrological modeling. The precipitation runoff modeling system of the US Geological Survey was modified in order to consi...
The role of climatic and terrain attributes in estimating baseflow recession in tropical catchments
climatic terrain attributes estimating baseflow recession tropical catchments
2010/12/22
The understanding of low flows in rivers is paramount more than ever as demand for water increases on a global scale. At the same time, limited streamflow data to investigate this phenomenon, particul...

Simulation of the snowmelt runoff contributing area in a small alpine basin
runoff contributing area alpine basin
2014/4/3
Simulation of areal snowmelt and snowcover depletion over time can be carried out by applying point-scale
melt rate computations to distributions of snow water equivalent (SWE). In alpine basins, thi...

2014/4/3
The partially decomposed organic layer (duff: F and H layers) of the forest floor is an important boundary between the soil
and atmospheric processes. Here we use both empirical data and a thre...
