His early research focused on:
- Tropical circulation
- Atmospheric waves
- Monsoon systems
- Ocean–atmosphere coupling
- Climate variability
Indian Institute of Tropical Meteorology (IITM)
A major part of Goswami’s career was spent at the Indian Institute of Tropical Meteorology (IITM), Pune, one of India’s premier atmospheric research institutions.
He served in several important scientific positions before becoming Director of IITM.
Under his leadership, IITM expanded research in:
- Climate modeling
- Monsoon prediction
- Numerical weather forecasting
- Earth system science

Monsoon Dynamics
B. N. Goswami is internationally recognized for his pioneering studies on the Indian summer monsoon.
His research has greatly improved understanding of:
- Monsoon onset and withdrawal
- Active and break phases of the monsoon
- Monsoon circulation
- Seasonal rainfall variability
- Extreme rainfall events
His work has helped improve seasonal monsoon prediction models.
Intra-Seasonal Oscillations
One of Goswami’s most influential scientific contributions has been the study of Monsoon Intra-Seasonal Oscillations (MISOs).
His research demonstrated how fluctuations within the monsoon season affect:
- Rainfall distribution
- Floods
- Droughts
- Agricultural productivity
These findings are now fundamental to modern monsoon forecasting.
Climate Change Research
Goswami has conducted important research on the effects of global warming on the Indian climate.
His studies have examined:
- Changes in rainfall patterns
- Increasing frequency of extreme rainfall events
- Climate variability
- Monsoon responses to global warming
- Future climate projections
His work has contributed to national and international climate assessments.
Ocean–Atmosphere Interaction
Another major area of his research has been understanding how the Indian Ocean influences weather and climate.
His investigations include:
- Sea surface temperature variability
- Air–sea heat exchange
- Indian Ocean Dipole (IOD)
- El Niño–Southern Oscillation (ENSO)
- Tropical ocean dynamics
These studies have enhanced long-range weather forecasting.
Scientific Leadership
Apart from research, Goswami has held several prestigious positions, including:
- Director of the Indian Institute of Tropical Meteorology (IITM)

His research transformed scientific understanding of the mechanisms governing the Indian summer monsoon, leading to more accurate forecasting.
2. Monsoon Intra-Seasonal Oscillations (MISOs)
He helped explain how fluctuations within the monsoon season control rainfall distribution and influence floods and droughts across India.
3. Extreme Rainfall Studies
Goswami’s research demonstrated that while the total seasonal rainfall may remain relatively stable, the frequency and intensity of extreme rainfall events over central India have increased in recent decades due to climate change.
4. Ocean–Atmosphere Coupling
His studies clarified the role of ocean temperatures and large-scale climate phenomena such as ENSO and the Indian Ocean Dipole in influencing monsoon variability.
5. Climate Modeling
He contributed to the development and improvement of climate models used for:
- Seasonal forecasting
- Climate projections
- Extreme weather prediction
- Disaster risk assessment
