Floodplain environmental change during the younger dryas and holocene: Evidence from the lower kennet valley, south central England [PDF]
, 2006 Many lowland rivers across northwest Europe exhibit broadly similar behavioural responses to glacial-interglacial transitions and landscape development. Difficulties exist in assessing these, largely because the evidence from many rivers remains limited

Operational assimilation of GPS slant path delay measurements into the MM5 4DVAR system
, 2011 A forward operator for Global Positioning System (GPS) slant total delay (STD) data and its adjoint were implemented into the Mesoscale Model version 5 (MM5) 4DVAR system to investigate its impact on quantitative precipitation forecasting (QPF).

Zhejiang Daxue xuebao. Lixue ban, 2006 对MM5V3模式中16组组合区域气候模拟试验所得的结果，分区域以RBF神经网络进行集成，分析了网络结构参数的不同对集成结果的影响，最后对整个区域的温度场进行了集成.结果表明：选择合适的网络结构参数是至关重要的，神经网络的非线性集成结果均明显优于单个参数化方案和16个方案线性集成的预测结果，整个区域的温度场集成结果比MM5模拟更接近于实况场，均方根误差场也较原MM5方案明显减小.这些结果对于区域气候的集成预测以及进一步优化神经网络的性能有一定的参考意义.
