CICS-NC: Tropical-Extratropical Interactions

Updated: 6 Jan, 2014

Archive

This is a new experimental page for tracking the interactions between tropics and extratropics.

• Map of the Multivariate PNA (MVP): Contours identify the EOF loading pattern for OLR and streamfunction while the shading shows the observed anomalies.
• Multivariate PNA (MVP) Time Series
  • Plot for last 90 days
  • Data for last 365 days
  • Data for 1979-2011
• Maps of recent OLR anomalies (shaded), 200-hPa streamfunction anomalies (contours), and 200-hPa total zonal wind (black contour at 50 m/s)
  • 1-day average
  • 3-day average
  • 5-day average
