NASA monitors potentially historic El Niño development

NASA is closely monitoring a new El Niño episode that could become the most powerful recorded since 1950. The phenomenon is characterized by unusual warming of equatorial Pacific waters, which disrupts wind patterns, redistributes ocean heat, and alters global precipitation.

In early October, the National Oceanic and Atmospheric Administration (NOAA) estimated an 83% probability of this intense scenario occurring. NASA satellites detected early indicators as far back as January, specifically identifying a warm water mass known as a Kelvin wave near Micronesia. These waves transport heat from west to east, weakening trade winds and contributing to rising sea levels in the eastern Pacific.

The environmental and economic impacts of such an event affect coastal communities, wildlife, agriculture, and emergency services globally.
