UFS AT All-Hands Meetings

The UFS S2S Application Team is joining efforts with the EMC Coupled Modeling Team in organizing monthly All-Hands meetings on UFS Coupled Global Model Evaluation on S2S Time Scales. Meetings  will be organized around S2S science topics, including prediction skill of the UFS and other models on this timescale, and new diagnostics designed to advance the understanding of Earth system variability of the S2S timescale. Another goal of these meetings is to identify projects that can be spun up to fill the gap in the model evaluation, improving the forecast skill, and how to communicate and apply the S2S forecasts. The format of the meetings will alternate between informal presentations followed by short discussions and informal discussions around topics of interest identified by the UFS S2S community.

Next Meeting: Friday, August 16th

  • Title: Evaluation on East Asian (EASM) and North American Summer Monsoon (NASM) for UFS High Resolution Prototypes 
    • Speaker: Wei Li, SAIC/EMC/NCEP
    • Abstract:  In this presentation, East Asian summer monsoon (EASM) and North American summer monsoon (NASM) indices in UFS high resolution prototypes (HR1, HR2 and HR3s) are first reviewed and compared with GFSv16. We then explored the mechanism for the biases before and after EASM and NASM onset from the perspective of the diabatic heating. The results show that EASM and NASM biases in the models are closely linked to the biases of the two major components of the diabatic heating (i.e. latent heating and radiative heating)

  • Title: Prediction of Diverse Boreal Summer Intraseasonal Oscillation in the GFDL SPEAR Model
    • Speaker: Baoqing Xiang, GFDL
    • Abstract: Boreal summer intraseasonal oscillation (BSISO) is a primary source of predictability for summertime weather and climate on the subseasonal-to-seasonal (S2S) time scale. In this talk, I will present the overall prediction skill of BSISO using the GFDL SPEAR model based on 20-yr hindcast experiments. Meanwhile, I will show results about the contrasting prediction skills between two types of BSISO (the so-called canonical BSISO versus northward dipole BSISO). What controls the BSISO prediction skill among individual events will be discussed. Finally, I will present some preliminary results illustrating the potential linkage between the canonical BSISO and the heat waves in North America.
