Polar/Tropical Climate Interaction Leads to 87F Northwest Russia

A large stretch (from the Dateline to tropical Africa) of tropical convection associated with the Madden Julian oscillation coupled with high latitude high pressure blocking (negative arctic oscillation) have combined to produce more extreme weather events. Included is a record 87F observed in Northwest Russia this past Sunday.

Sudden Emergence of -NAO Pattern

A strong negative North Atlantic oscillation climate pattern has emerged and may last much of the remainder of meteorological spring. Implications include more wet weather for the U.S. and a general cool thermal regime and potentially prohibitive rains in Eastern Europe/Western Russia.

Are El Nino Global SSTA Patterns Changing?

Modern-day El Nino episodes have a tendency to occur while many other parts of the global oceans are also warmer than normal. This observation is a large change from the previous strong El Nino episodes of 1982-83/1997-98 when most of the oceanic heat and influence on atmospheric climate was consolidated in the tropical East Pacific. Consequently, our understanding of El Nino climate rooted in the influence on the atmosphere by the 1982-83/1997-98 warm ENSO events is different for many regions.
