Muhammad Azhar Ehsan

Climate scientist. Forecaster. Storyteller of a changing planet.

I study how the oceans and atmosphere shape our climate — from El Niño to the South Asian monsoon — and how we can predict their swings to help societies prepare for what comes next.

What I work on

Understanding and predicting our climate

My research sits at the intersection of climate dynamics, prediction science, and real-world application — turning physics into forecasts, and forecasts into action.

Ocean–Atmosphere

ENSO & Tropical Variability

Dynamics of El Niño–Southern Oscillation, the Indian Ocean Dipole, and how tropical oceans shape global climate.

Monsoons

Monsoons & Regional Climate

South Asian and African monsoons — drivers of variability, predictability, and impacts on water and food systems.

S2S

Subseasonal-to-Seasonal Prediction

Improving forecasts on the weeks-to-months horizon using multi-model ensembles (NMME, SubX, S2S, C3S).

AI / ML

AI for Earth System Prediction

Machine learning and foundation models for understanding predictability and skill.

Impact

Forecast Applications

Translating predictions into actionable information for agriculture, water, health, and disaster risk.

Decadal

Decadal Variability

Interannual-to-decadal climate variability and windows of opportunity for prediction.

Let's collaborate

I'm open to research collaborations, talks, mentoring, and projects that bring climate science closer to the people who need it most.
