A flux-form semi-Lagrangian transport scheme (FFSL) was implemented in a spectral atmospheric general circulation model (GCM) developed and used at IAP/LASG.Idealized numerical experiments show that t
Freeze-thaw processes in soils, including changes in frost and thaw fronts (FTFs), are important physical processes.The movement of FTFs affects soil water and thermal characteristics, as well as ener
CFRAM (Climate Feedback-Response Analysis Method)基于耦合的地表-大气能量平衡方程,通过对局部各项能量通量分别求解线性红外辐射传输方程,可将各项能量扰动所造成的温度变化进行线性的定量分解.本文利用CFRAM方法对气候系统模式FGOALS-s2模拟的冬、夏季地面平均温度(1979-2005)相对于ERA-Interim再分析资料的偏差,进行了归因分析.

为改进LICOM对高纬度海洋环流的模拟能力,以及提高动力框架的计算精度,我们将LICOM原本基于经纬网格的差分格式改进为可以基于任意正交曲线的差分格式,而且可以保证原有所有的守恒性质不变.同时,我们还进一步改进的LICOM模式的MPI并行剖分方案,提高了模式的并行效率.
从消光光谱的测量反演粒子的尺度分布(PSD)是一个具有挑战性的问题,特别是对非球形粒子.假设所有的粒子都是同一固定取向,且其消光截面可以充分用反常衍射理论(ADT)计算,据此,我们利用积分变换理论提出了一系列非球形(包括椭球,长方体,三角柱体,六角柱体,椭圆柱体)的解析反演算法,并发现:(1)就所考虑的每种非球形粒子而言,尺度分布和消光谱之间存在一个ADT变换,这有助于我们理解反问题的物理本质,A
Climate variability in the Southern Hemisphere (SH) extratropical regions is dominated by the SH annular mode (SAM).Future changes in the SAMcould have a large influence on the climate over broad regi
This study identifies a decadal shift of summer surface air temperature (SAT) over the Northeast Asia, including the southeastern part of Russia, Mongolia and northern China, around the mid-1990s.
This study examines the relationship between the zonal oscillation of the western Pacific subtropical high (WPSH) and underneath sea surface temperature (SST) variation on a subseasonal time scale, as
CORDEX东亚区域包含了大部分的西太平洋和东印度洋,RegCM3物理过程参数的默认设定在该区域(特别是海洋区域)的模拟偏差较大.我们利用快速模拟退火(MVFSA)的采样技术,针对RegCM3的MIT-EMANUEL对流参数化方案在CORDEX的性能进行了优化.
