Synoptic meteorology and climatology
- Local weather systems: extratropical cyclones, blocking
- Summer monsoon: atmospheric river, Changma
Large-scale atmospheric dynamics
- Large-scale circulations: Hadley Cell, westerly jet, teleconnection
- Stratosphere-troposphere coupling: Antarctic ozone, Quasi-Biennial Oscillation (QBO), Stratospheric Sudden Warming (SSW)
Long-term climate change and variability
- Global warming
- Short-lived climate forcers (SLCFs) and their climate impacts
- Stratospheric ozone depletion/recovery and their climate impacts
Atmospheric and climate predictability
- Subseasonal-to-seasonal (S2S) prediction
- Near-term climate prediction
