Presented on September 17, 2025, by Dr. Hongwei SunFacultyDepartment of Atmospheric SciencesUniversity of Hawai’i at Mānoa ABSTRACT: Numerical models have become important tools for scientists to understand the complex climate system. Various types of numerical models (e.g., Lagrangian vs. Eulerian
Dynamics of MJO Eastward Propagation
Presented on September 10, 2025, by Professor Tim LiAtmospheric Sciences DepartmentUniversity of Hawaii at Manoa ABSTRACT: The madden-Julian Oscillation (MJO) is a large-scale low-frequency mode in the tropical atmosphere, and it represents a major predictability source for sub-seasonal forecast. Many current
