Reanalysis time machine

Scrub to any day since 1950 and read off the state of every major teleconnection — ENSO, the MJO, PNA, AO, NAO, EPO, WPO, QBO, PDO, SOI. Use the date picker, the ◀ ▶ buttons, the ← → keys (hold Shift for ±30 days), or Play to animate. Toggle the map between that day’s 24-hour precipitation and the 500 hPa upper-air pattern.
