ENSO - El Nino Southern Oscillation
The author of this site had the distinct pleasure of being introduced to the ENSO phenomenon,  by one of the first practitioners that utilized ENSO data, in an operational weather forecasting mode, Edward (Ted) Edie, of the New Zealand Meteorogical Service. Ted Edie was regarded as a pioneering practical meteorologist by his peers.

Our knowledge of the implications of the ENSO together with the North Atlantic Oscillation (NAO) and the Madden-Jullian Oscillation (MJO) is far from complete. We have only recently started to understand the global implications on weather and climate that these atmospheric modulations induce. An animation of the ENSO scenarios: http://esminfo.prenhall.com/science/geoanimations/animations/26_NinoNina.html
As stated in a recent paper:
"...the findings reported here indicate that atmospheric processes that are part of the ENSO cycle are collectively a major driver of temperature anomalies on a global scale."

This site provides real-time data on the Solar wind as measured by the ACE spacecraft. In addition, there is information on solar flares, aurora alerts, the ozone layer and other interesting space information.

​A New 200‐Year Spatial Reconstruction of West Antarctic Surface Mass Balance 
Key Points
  • A new reconstruction of spatially complete surface mass balance over the West Antarctic Ice Sheet during the past 200 years is presented
  • West Antarctica experiences a significant negative SMB trend during the nineteenth century, but a significant positive trend during 1900–2010
  • The WAIS east‐west dipole SMB trends are associated with positive polarity of Southern Annular Mode (SAM) and dominant La Niña events
