NASA uyduları rekor düzeyde olabilecek bir El Niño’yu izliyor

NASA satellites are tracking what could become an exceptionally powerful El Niño. As of October, NOAA estimated an 83% probability that the strongest event since 1950 is under way. El Niño, a natural pattern that returns roughly every two to seven years, warms parts of the equatorial Pacific. Early signs appeared in January 2026, when a Kelvin wave, a long, slow pulse of warm water, was spotted near Micronesia. As such waves carry heat eastward, the air above warms and rises, weakening the trade winds and letting eastern sea levels and temperatures climb further. By early April the warm water had reached the eastern Pacific, where the sea surface is now about 1.7°C above the long-term average. The ocean’s colour is changing as well: NASA’s PACE satellite shows equatorial waters turning bluer, because weaker winds bring fewer nutrients up from the deep, so phytoplankton become less abundant.
