On March 30, 2019, Arctic sea ice extent was 13.42 million km², a record low for the measurements at ads.nipr.ac.jp for the time of year.


[ click on images to enlarge ]As the Arctic warms up faster than the rest of the world, the temperature difference between the North Pole and the Equator narrows, making the jet stream wavier, thus enabling warm air over the Pacific Arctic to move more easily into the Arctic.

The image on the right shows that, on March 31, 2019, the Arctic was 7.5°C or 13.5°F warmer than 1979-2000.

The earlier forecast below shows a temperature anomaly for the Arctic of 7.6°C or 13.68°F for March 31, 2019, 12:00 UTC and in places 30°C or 54°F warmer. The inset shows the Jet Stream moving higher over the Bering Strait, enabling air that has been strongly warmed up over the Pacific Ocean to move into the Arctic.


A wavier Jet Stream also enables cold air to more easily move out of the Arctic. The inset shows the Jet Stream dipping down over North America where temperatures lower than were usual were recorded.

The later forecast below shows a temperature anomaly for the Arctic of 7.7°C or 13.86°F for March 31, 2019,
