Exchange between air and sea are also important factors that affect the climate on earth.<\/p><\/div>[vc_column_text]<\/p>\n<p style=\"text-align: center;\">The weather and climate are changing, both locally and globally, and extreme events such as tropical cyclones, polar low pressures, monster waves, storm surges, heat waves, and extreme rainfall situations are increasing in frequency and scope. The interaction between air and sea plays an important role in this development. The interaction also affects waves and ocean currents, the distribution of nutrient salts and the ecosystems in the sea.<\/p>\n<p style=\"text-align: center;\">It is demanding to study these processes. We have expertise in using measurements from satellites and advanced ocean sensors, in combination with physical models. We develop new methods for using measurements from satellites, and continuously improve the models used so that more accurate calculations and more secure forecasts for the future can be delivered. By studying the development of extreme events, we gain an increased understanding of where and why the events occur, how the climate will develop and what consequences the development will have.<\/p>\n<p>[\/vc_column_text]<div class=\"spacer\" style=\"--space-sm: 15px;--space-md: 15px;--space-lg: 15px;--space-xl: 15px;\"><\/div><div class=\"infobox teal\">\n<p style=\"text-align: center;\">For more information, contact <a href=\"https:\/\/nersc.no\/en\/ansatt\/antonio-bonaduce\/\"><strong>research leader Antonio Bonaduce<\/strong><\/a>.<\/p>\n<\/div><div class=\"spacer\" style=\"--space-sm: 15px;--space-md: 15px;--space-lg: 15px;--space-xl: 15px;\"><\/div>[\/vc_column][vc_column width=&#8221;1\/6&#8243;][\/vc_column][\/vc_row][\/vc_section][vc_row][vc_column]<div class=\"spacer\" style=\"--space-sm: 30px;--space-md: 30px;--space-lg: 30px;--space-xl: 30px;\"><\/div><div class=\"header left  \"><h2 class=\"heading-3\" title=\"News\">News<\/h2><\/div>                <script type=\"text\/javascript\">\n                postSettings = {\n                    'categories': '80',\n                    'posttypes': 'post',\n                    'limit': '',\n                    'offset': '',\n                    'ignoresticky': '',\n                    'showsticky': '',\n                    'paging': '',\n                    'acfmeta': '',\n                    'order': 'desc',\n                    'orderby': 'date',\n                    'metakey': '',\n                    'metatype': '',\n                    'includeposts': '8044,7004',\n                    'excludeposts': '',\n                    'grid': 'col-lg-4 col-md-6 col-sm-12'\n                };\n                <\/script><div class=\"vc-loop-posts row\">    <div class=\"col-lg-4 col-md-6 col-sm-12\">\n\t\t<article class=\"WP_Post has-image vc-loop-news\" id=\"post-8044\">\n\t\t\t<div class=\"inner-article\">\n\t\t\t\t<a href=\"https:\/\/nersc.no\/en\/features\/new-knowledge-about-the-impact-of-the-ocean-on-the-climate\/\" title=\"New knowledge about the impact of the ocean on the climate\">\n\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"346\" src=\"https:\/\/nersc.no\/wp-content\/uploads\/2025\/09\/pexels-pok-rie-33563-5799946-2-1024x346.jpg\" class=\"attachment-large size-large wp-post-image\" alt=\"\" srcset=\"https:\/\/nersc.no\/wp-content\/uploads\/2025\/09\/pexels-pok-rie-33563-5799946-2-1024x346.jpg 1024w, https:\/\/nersc.no\/wp-content\/uploads\/2025\/09\/pexels-pok-rie-33563-5799946-2-300x101.jpg 300w, https:\/\/nersc.no\/wp-content\/uploads\/2025\/09\/pexels-pok-rie-33563-5799946-2-768x259.jpg 768w, https:\/\/nersc.no\/wp-content\/uploads\/2025\/09\/pexels-pok-rie-33563-5799946-2-1536x519.jpg 1536w, https:\/\/nersc.no\/wp-content\/uploads\/2025\/09\/pexels-pok-rie-33563-5799946-2-2048x692.jpg 2048w, https:\/\/nersc.no\/wp-content\/uploads\/2025\/09\/pexels-pok-rie-33563-5799946-2-520x176.jpg 520w, https:\/\/nersc.no\/wp-content\/uploads\/2025\/09\/pexels-pok-rie-33563-5799946-2-800x270.jpg 800w, https:\/\/nersc.no\/wp-content\/uploads\/2025\/09\/pexels-pok-rie-33563-5799946-2-1600x540.jpg 1600w, https:\/\/nersc.no\/wp-content\/uploads\/2025\/09\/pexels-pok-rie-33563-5799946-2-1920x648.jpg 1920w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/>\n\t\t\t\t\t<div class=\"text\">\n\t\t\t\t\t\t<span class=\"category features\">Features<\/span>\n\t\t\t\t\t    <h2 class=\"title\">New knowledge about the impact of the ocean on the climate<\/h2>\n\t\t\t\t\t    <div class=\"ingress\"><\/div>\n                    <\/div>\n                    <footer class=\"footer\">\n                        <div class=\"date\">1.
