A rare climate event is taking shape over the Atlantic Ocean while El Nino continues to influence weather across the globe. Scientists say the cooling pattern, known as Atlantic Nino, could become only the sixth such event recorded in the past 40 years if present ocean conditions continue.
Atlantic Nino After 4 Decades
Recent data from the National Oceanic and Atmospheric Administration shows a sharp contrast between the Pacific and Atlantic oceans. While El Nino has warmed the Pacific, the eastern equatorial Atlantic is experiencing below average sea surface temperatures. Atlantic Nino is different from the Pacific based La Nina, but both involve unusually cool waters in their respective regions. Experts say the event will be officially confirmed if sea surface temperatures remain at least 0.5 degrees Celsius below average for two overlapping seasons. Meteorologists also believe El Nino and Atlantic Nino can work together to influence atmospheric circulation despite developing over different oceans.
Fewer Hurricanes Could Develop:
Cooler Atlantic waters reduce the heat and moisture needed for powerful thunderstorms, making it harder for tropical cyclones and hurricanes to form. NOAA expects the 2026 Atlantic hurricane season to produce eight to fourteen named storms, including three to six hurricanes and one to three major hurricanes. By July 17, only two named storms had formed, with Tropical Storm Arthur being the only active named system so far.
Stronger Monsoon for India:
Atlantic Nino is associated with stronger Indian summer monsoon rainfall. Although the India Meteorological Department initially forecast below normal and uneven rainfall during July, several states have instead experienced intense rain. Heavy rainfall is expected across northern, eastern, and central India until July 20, while Ladakh has already recorded rainfall about 65 percent above normal. Scientists say the rare combination of El Nino and Atlantic Nino could result in fewer Atlantic hurricanes but a more active monsoon over India.
