Research interests

In recent 10 years, my research work are mainly focused on development of atmospheric general circulation model (AGCM) and organizing of coupled climate system model (CCSM) development, new approaches of data assimilation and their applications.


The research work on AGCM include the design of dynamical core of the Grid-point Atmospheric Model of IAP LASG (GAMIL), the improvement of its physical parameterization schemes and its applications to the studies on the Esatern Asian climate. The dynamical core of the GAMIL was designed using a new semi-implicit finite difference scheme with exact physical conservations to solve the primitive equations of baroclinic atmosphere with hydrostatic equilibrium. The scheme incorporates an implicit conservation scheme for the terms of surface gravity-wave propagation along the zonal parallels and an explicit conservation scheme for the other terms of the equations. The use of the implicit conservation scheme for zonal surface gravity-wave equations makes the dynamical core well stable, without any filtering or smoothing at the polar regions. The deduction of standard atmospheric stratification greatly reduces the negative influence of high and steep mountains on model performance. The skillful combination of the implicit and explicit conservation schemes makes the total mass and effective energy exactly conserved by the new dynamical core.


Since 2000, I have been contributing to the organizing and development of the new generation of the LASG climate system model, the Flexible Global Ocean-Atmosphere-Land System (FGOALS) Model. This is a fully-coupled, global climate model that provides state-of-the-art computer simulations of the Earth's past, present, and future climate states. It consists of a coupler and 4 main component models. It uses the CPL5 from NCAR as the coupler. It has two options of atmospheric component model: one is the grid-point atmospheric model IAP LASG (GAMIL) and the other is the spectral atmospheric model of IAP LASG (SAMIL). Both GAMIL and SAMIL are two state-of-the-art AGCMs developped by the LASG model group. The ocean component of the FGOALS is the LASG/IAP climate ocean model (LICOM), which is a state-of-the-art ocean general circulation model (OGCM) developed in LASG since 1980s. The components of land surface model and sea ice model are respectively the CLM2 and the CSIM4, which are introduced from NCAR. The FGOALS is one of the 24 IPCC AR4 models. It has been used for many applications, including ocean-atmosphere-land interactions in the areas of the Asia, Indian Ocean and Pacific, studies on regional climate (e.g. Asian monsoon, Pacific subtropic high and land-amtosphere system in Tibetan Plateau etc.) and global climate, paleoclimate simulation, and so on. This model provided the important bases and framework for the development of the on-going earth system model of LASG.


Other related studies on model development include the improvements of a dynamic global vegetation model and simulations of carbon and water at an upland-oak forest, development of ocean data assimilation system of LICOM for climate prediction by FGOALS, the simulation study of tropospheric ozone over Europe with MOZART22, and the evaluation of the atmospheric transport in GAMIL using radon measurements: sensitivity to cumulus convection parameterization, which are not introduced here in detail.


On the study of data assimilation, a new approach to data assimilation, noted as `three-dimensional variational data assimilation of mapped observation (3DVM)', was proposed, based on the new concept of mapped observation and the new idea of backward 4DVar. Like the available 4DVar, 3DVM produces an optimal initial condition (IC) that is consistent with the prediction model due to the inclusion of model constraints and best fits the observations in the assimilation window through the model solution trajectory. Different from the 4DVar, the IC derived from 3DVM is located at the end of the assimilation window rather than at the beginning conventionally. This change greatly reduces the computing cost for the new approach, which is almost the same as that of the three-dimensional variational data assimilation (3DVar). Especially, such a change is able to improve assimilation accuracy because it does not need the tangential linear and adjoint approximations to calculate the gradient of cost function. Therefore, in numerical test, the new approach produces better IC than 4DVar does for 72-h simulation of TY9914 (Dan), by assimilating the three-dimensional fields of temperature and wind retrieved from the Advanced Microwave Sounding Unit-A (AMSU-A) observations. Meanwhile, it takes only 1/7 of the computing cost that the 4DVar requires for the same initialization with the same retrieved data.
Many work on numerical methods were done in the earily time (before 1997).
