Real-time Climate Observer – Coming Soon

We have developed software which can scan the current climate. With this information, we are able to determine the jet stream position (by Sonja Totz) and quantify its amount of meandering (by Giorgia di Capua). We are also scanning the atmosphere to detect when the jet stream is more likely to resonate (by Kai Kornhuber) and cause high amplitude meanders, which are often associated with more extreme weather events.
