Sahara Desert Migrates North into EuropeBrent Herbert 17 Jul 2007 12:25 GMT
In another weird weather development the Sahara Desert has been pushing Northward into Europe this summer. This is being caused by a very persistent and very rude northerly curvature of the Jet Stream. Normally this Jet Stream would be over Northern Africa and would keep the heat of the Sahara Desert trapped on the Sahara, but with this northerly curvature of the Jet Stream the damaging heat of the Sahara desert has now migrated north into central Europe, where it has been sitting for weeks now. You can see this northerly curve in the Jet Stream in blue on the Image of Europe from the Wunderground weather website. Countries all over Middle Europe are reporting temperatures around 100 degrees. Meanwhile, one consequence of this shift has been that humidity from Africa’s tropical jungles is now pushing northward onto the Sahara, as you can see in the humidity map of Africa from the Wunderground site.
