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
Maps of recent OLR anomalies (shaded), 200-hPa streamfunction anomalies (contours), and 200-hPa total zonal wind (black contour at 50 m/s)
Maps of 500-hPa geopotential height anomalies (contoured every 30 m) and significant 850-hPa temperature anomalies, as shown in Schreck et al. (2013).
