Atmosphere

The general circulation of the atmosphere and the connectivity between different regions are areas of interest for us.

Idian Ocean Dipole

Key Points

Indian Ocean Dipole (IOD)’s Rossby wave train is partially similar to the climatology; a negative IOD enormously increases zonal wavenumber 3
IOD (El Niño Southern Oscillation) is negatively (positively) correlated with zonal wavenumber 2 and 3 (1) in austral spring
The extremely positive IOD in 2019 exhibited more significant increases and unusual changes in wave patterns
