Smoke over North America

High levels of biomass-burning aerosols show up over North America on the above June 7, 2023 06 UTC forecast by Copernicus. The above satellite image shows the US East Coast, with New York blanketed in a veil of smoke on June 7, 2023.    High levels of carbon monoxide are visible over North America on the above map. Carbon monoxide is forecast to be as high as 8715 parts per billion in Quebec, Canada on June 8, 2023 (at 12:00 UTC, a few hours from now, at the green circle). The map below shows the location for this measurement in Quebec, Canada on June 8, 2023 (at red marker).  The image below also shows wind at 250 hPa, i.e. the Jet Stream. The circular wind patterns indicate how deformed the Jet Stream is.  The image below, from an earlier post , further illustrates the extent of the deformation of the Jet Stream, showing the Jet Stream on June 6, 2023, with no less than 26 circular wind patterns (at 250 hPa) marked on the image, which also shows sea surface tempe...

Arctic Sea Ice Gone By September 2019?

Record low Arctic sea ice extent for the time of year Arctic sea ice minimum extent typically occurs about half September. In 2012, minimum extent was reached on September 17, 2012, when extent was 3.387 million km². On July 28, 2019, Arctic sea ice extent was 6.576 million km². How much extent do you think there will be by September 17, 2019? From July 28, 2019, to September 17, 2019, that's a period of 52 days during which a lot of melting can occur. Could there be a Blue Ocean Event in 2019, with virtually all sea ice disappearing in the Arctic? Consider this. Extent was 6.926 million km² on September 17, 1989. Extent was 3.387 million km² on September 17, 2012, so 3.539 million km² had disappeared in 23 years. Over those years, more ice extent disappeared than what was left on September 17, 2012. The question is how much sea ice extent will be left when it will reach its minimum this year, i.e. in September 2019. The red dashed line on the image at the top continues the path of...
