Agnirva Space Premier League - Expedition #32567: Storm Spotting from Space: How the ISS Helps Predict Cyclone Intensity

Cyclones are some of the most destructive natural disasters on Earth, and accurate forecasting is critical for saving lives and property. The 'Cyclone Intensity Measurements from the ISS (CyMISS)' project, led by Dr. Paul Joss from MIT and supported by NASA, is a game-changing step in improving storm prediction.

Using a specially designed optical imaging system aboard the ISS, CyMISS captures high-resolution images of tropical cyclones from above. Unlike weather satellites in geostationary orbits, the ISS orbits closer to Earth, allowing it to see storms in greater detail.

The key objective of CyMISS is to measure the height and structure of a cyclone’s eyewall — the ring of towering clouds surrounding the calm eye. These details are crucial for estimating storm strength, as higher and more organized eyewalls typically signal intensifying storms.

The experiment uses a combination of visible light and infrared sensors to analyze cloud shapes, heights, and temperature gradients. Data collected are then compared with readings from aircraft and traditional satellites.

CyMISS has already demonstrated that ISS imagery can accurately track changes in storm structure, even in remote ocean regions where other systems may not provide real-time coverage. This makes it a valuable tool for meteorologists and disaster response teams.

Beyond forecasting, the data also help researchers understand how cyclones form and evolve. This could lead to new models that predict not just strength but also rainfall and potential for storm surge.

By enhancing early warning systems, CyMISS directly contributes to global disaster preparedness and resilience.

This experiment highlights the ISS’s value not only as a space lab but also as a powerful observation platform for Earth sciences.
