MYJ和YSU方案对WRF边界层气象要素模拟的影响
大气边界层方案 温度层结 风速 边界层高度 整体Richardson数
2013/11/6
研究新一代中尺度气象模式WRF中两种大气边界层方案(MYJ,YSU)对沈阳冬季大气边界层结构模拟的影响,重点分析温度层结、低层风场、边界层高度等对污染物扩散有重要影响的气象要素.和观测数据的比对表明WRF基本能够模拟出温度风速的日变化特征,但模拟风速偏大.YSU方案由于模拟的边界层顶卷挟和边界层内混合作用较强,夜间接地逆温强度低于MYJ方案,逆温维持时间比MYJ方案短4小时,同时模拟边界层高度也高...
Ignition from a Fire Perimeter in a WRF Wildland Fire Model
Ignition Fire Perimeter WRF Wildland Fire Model Atmospheric and Oceanic Physics

CAMS云微物理方案的改进及与WRF模式耦合的个例研究
CAMS 微物理方案 WRF 耦合
2012/4/1
本文在中国气象科学研究院(CAMS)双参数云微物理方案的基础上,增加气溶胶粒子的活化过程,改进原方案中的水汽混合比、云水混合比及云滴数浓度的预报方程,实现对各种水成物(包括云水)的混合比和数浓度的预报.此外,改进后的CAMS云方案被成功耦合到了WRF v3.1中尺度模式.本文利用耦合模式对2009年4月23~24日发生在我国北方地区的一次降水天气过程进行了模拟,将新方案的模拟结果与WRF自带的3个...
