Scale-dependency of surface fluxes in an atmospheric mesoscale model: effect of spatial heterogeneity in atmospheric conditions [PDF]
Nonlinear Processes in Geophysics, 2008 We examined the nonlinear effect of spatial heterogeneity in atmospheric conditions on the simulation of surface fluxes in the mesoscale model, MM5 by testing their scale-invariance from a tower footprint to regional scales.

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.

Ensemble‐based simultaneous state and parameter estimation with MM5
Geophysical Research Letters, 2006 The performance of the ensemble Kalman filter (EnKF) under imperfect model conditions is investigated through simultaneous state and parameter estimation for a numerical weather prediction model of operational complexity (MM5). The source of model error is assumed to be the uncertainty in the vertical eddy mixing coefficient.

Developing a high-resolution wind map for a complex terrain with a coupled MM5/CALMET system [PDF]
, 2007 This study investigates the wind energy potential in Hong Kong, a region with a complex terrain, by coupling the prognostic MM5 mesoscale model with the CALMET diagnostic model to produce high-resolution wind fields. Hourly wind fields were simulated for

Shuitu Baochi Xuebao, 2005 结合中尺度大气模式MM5和Shao的风蚀起沙方案,对敦煌莫高窟顶灌木林带和草方格沙障的固沙效应进行数值模拟研究。结果表明:灌木林带的建立,使其地表风蚀起沙的临界摩擦速度(ut)达到1.15m/s,是林带建立前的4.1倍,地表的顺风向沙粒通量(Q)和垂直尘粒通量(F)均减小为0,完全抑制了地表风蚀起沙;草方格沙障的设置,使ut达到0.53m/s,为设置前的1.9倍,Q和F分别减少约3/5和7/8,固沙效果非常明显。一般情况下,ut不会大于1.0m/s,充分说明灌木林带比草方格具有更强的固沙效果 ...
