Did you know that a weakened polar vortex (a band of strong winds above the North or South Poles) can lead to extremely cold weather & snow in other places? But what can cause a weak polar vortex? Find out what @HamoudaMosti & other researchers learned: https://t.co/zhfVbMfc2N
Events, in which the tropospheric variability is not following the stratosphere (Stratosphere-Troposphere Decoupling) are discussed. We propose that such events are associated with SST patterns limited to lower mid-latitude.

Fascinating how GFS changed a lot overnight! From a PV split, to a displacement to Europe.

SST continues to break records! The global average is 0.3 ยฐC higher than the most extreme record, and 0.8 ยฐC higher than the average at this time of the year.
