This International Laboratory for High-Resolution Earth System Prediction (iHESP) seeks to develop a new advanced modeling framework for high-resolution multiscale Earth System predictions and provide reliable information at both global and regional scales, taking full advantage of the combined expertise of three world-class institutions, Qingdao Pilot National Laboratory for Marine Science and Technology (QNLM), Texas A&M University (TAMU), and National Center for Atmospheric Research (NCAR).
iHESP’s goal is to advance challenging fundamental science and technology in Earth system modeling and prediction.
Cutting Edge Research
Model Simulation of West Pacific Typhoons
High-Resolution Global Coupled Climate Modelling
Current coarse resolution global coupled models have limited skill in simulating climate and weather extreme events like tropical cyclones, winter storms, drought and flooding. One area of research at iHESP is to study whether high atmospheric model resolution to permit tropical cyclones and high ocean model resolution to resolve mesoscale processes improve the model skill.
High-Resolution Ensemble Decadal Climate Prediction
Can a high-resolution coupled model which resolves frontal and meso-scale ocean-atmospheric interactions improve the realism of simulated climate variability and predictions at seasonal-to-decadal scales? This is another question we are interested in exploring. We use ensembles of high-resolution and low-resolution model simulations to answer this question.
Regional Downscaling
It is prohibitively expensive to run global models at convection resolving atmospheric and sub-mesoscale resolving ocean resolutions. We are developing tools and methods for online regional dynamic downscaling at iHESP.
Online Coupled Data-Assimilation
We are actively working on developing an online coupled data-assimilation system using an ensemble Kalman filter (EnKF). This new data assimilation capability will be implemented to both regional and global models.
Modelling Tools
At iHESP, we use the Community Earth System Model (CESM), Weather Research and Forecast (WRF) model, and Regional Ocean Modelling System (ROMS). We also develope methods to couple these three models together using CESM/CIME framework.
