Evaluation of alternative formulae for calculation of surface temperature in snowmelt models using frequency analysis of temperature observations
alternative formulae surface temperature snowmelt models frequency analysis temperature observations
2010/4/7
The snow surface temperature is an important quantity in the snow energy balance, since it modulates the exchange of energy between the surface and the atmosphere as well as the conduction of energy i...

Multilevel and multiscale drought reanalysis France Safran-Isba-Modcou hydrometeorological suite
2010/4/7
Physically-based droughts can be defined as a water deficit in at least one component of the land surface hydrological cycle. The reliance of different activity domains (water supply, irrigation, hydr...
Towards understanding hydroclimatic change in Victoria，Australia——preliminary insights into the “Big Dry”
hydroclimatic change Victoria preliminary insights Big Dry
2010/4/7
Since the mid-1990s the majority of Victoria, Australia, has experienced severe drought conditions (i.e. the "Big Dry") characterized by streamflow that is the lowest in approximately 80 years of reco...
2.5ka来新疆吉力湖湖泊沉积记录的气候环境变化
吉力湖 过去2ka 多指标分析
2010/12/28
选择位于西风区的吉力湖为研究对象，利用210Pb、137Cs和AMS14C测年手段，建立了吉力湖沉积岩芯2.5ka以来的时间序列.对湖泊沉积物的粒度、总有机碳、总氮以及有机碳同位素等多环境指标的综合分析，重建了吉力湖2.5ka以来的气候环境演化特征. 2.5ka以来吉力湖气候环境变化大致经历了5个阶段：500BC-50BC，暖干；50BC-650AD，冷湿，气候不稳定，冷暖波动较大；650-135...
Climate and terrain factors explaining streamflow response and recession in Australian catchments
Climate and terrain factors streamflow response recession Australian catchments
2010/2/1
Daily streamflow data were analysed to assess which climate and terrain factors best explain streamflow response in 183 Australian catchments. Assessed descriptors of catchment response included the p...
