Tracking the Giant Ocean Swells of El Niño from Orbit
The Sentinel-6 Michael Freilich satellite, a joint mission between NASA and the European Space Agency, has detected massive shifts in the equatorial Pacific Ocean.
Observational data confirms that enormous bands of warm water, known as Kelvin waves, are actively traveling eastward and arriving off the coast of South America.
Because water physically expands as it warms, using satellites to measure sea surface height is the most reliable method to determine how much heat is stored beneath the ocean’s surface.
These abnormal elevations in sea level serve as a clear and undeniable indicator that a powerful El Niño climate pattern is once again beginning to unfold.
Scientists at the Jet Propulsion Laboratory have warned that the current oceanic activity strongly resembles the conditions seen prior to the devastating El Niño event of 1997.
By providing early warnings of this climate shift, which is known to drive up global temperatures and trigger extreme floods and droughts worldwide, satellite data acts as our first line of defense.
The advanced technology used to monitor our planet’s oceans from orbit has become a crucial lifeline, helping global communities prepare for future natural disasters.
It is truly remarkable to see how exploring the cosmos also empowers us to protect and understand the delicate environment of our home planet.
