  1. 20 de abr. de 2022 · Scientists at PSL are working to characterize marine heatwaves, understand how they form and dissipate, and predict them in advance. On this page, we will provide current ocean maps, forecasts of heatwaves, interactive tools for users to explore ocean heatwaves themselves, links to research results and to webpages at other institutions.

  2. 14 de jul. de 2023 · NOAA scientists have tracked a steady climb in ocean temperatures since April 2023, which is causing unprecedented heat stress conditions in the Caribbean Basin, including waters surrounding Florida and in the Gulf of Mexico. More isolated marine heat wave conditions have been detected off the Northeast U.S. coast, along the path.

  3. Heat waves form when high pressure aloft, from 10,000 to 25,000 feet (3,000 to 7,600 meters), strengthens and remains over a region for several days up to several weeks. This is common in summer in both Northern and Southern Hemispheres as the jet stream “follows the sun”.

  5. Extraordinary heat events occur around the planet during most summers, but the current heatwave in the Pacific Northwest is truly exceptional. In June 2021, all-time temperature records fell in multiple cities in the U.S. and Canada during a heatwave that the National Weather Service called “historic and dangerous.”.

  6. 6 de sept. de 2023 · The main source of ocean heat is sunlight. Additionally, clouds, water vapor, and greenhouse gases emit heat that they have absorbed, and some of that heat energy enters the ocean. Waves, tides, and currents constantly mix the ocean, moving heat from warmer to cooler latitudes and to deeper levels.

  7. 5 de sept. de 2019 · The marine heatwave that has formed off the West Coast of North America is currently close to the warmest area in the Pacific Ocean.
