mai capito il grafico della mjo

The Madden–Julian oscillation (MJO) is the largest element of the intraseasonal (30- to 90-day) variability in the tropical atmosphere. It was discovered in 1971 by Roland Madden and Paul Julian of the American National Center for Atmospheric Research (NCAR). It is a large-scale coupling between atmospheric circulation and tropical deep convection.^[1]^[2] Unlike a standing pattern like the El Niño Southern Oscillation (ENSO), the Madden–Julian oscillation is a traveling pattern that propagates eastward at approximately 4 to 8 m/s (14 to 29 km/h, 9 to 18 mph), through the atmosphere above the warm parts of the Indian and Pacific oceans. This overall circulation pattern manifests itself most clearly as anomalous rainfall.
The Madden–Julian oscillation is characterized by an eastward progression of large regions of both enhanced and suppressed tropical rainfall, observed mainly over the Indian and Pacific Ocean. The anomalous rainfall is usually first evident over the western Indian Ocean, and remains evident as it propagates over the very warm ocean waters of the western and central tropical Pacific. This pattern of tropical rainfall then generally becomes nondescript as it moves over the cooler ocean waters of the eastern Pacific (except over the region of warmer water off the west coast of Central America) but occasionally reappears at low amplitude over the tropical Atlantic and higher amplitude over the Indian Ocean. The wet phase of enhanced convection and precipitation is followed by a dry phase where thunderstorm activity is suppressed. Each cycle lasts approximately 30–60 days. Because of this pattern, the Madden–Julian oscillation is also known as the 30- to 60-day oscillation, 30- to 60-day wave, or intraseasonal oscillation.

Scusate una info.
Per ora questi primi 24-25 giorni di gennaio a Rimini e dintorni riescono a farlo da podio come gennaio più caldo? avete un po' di dati? grazie

qui secondo a ieri 7.1 contro l'ormai irraggiungibile 2014 a 7.5

Per portare quella roba sotto le 100h mancano solo 40 run di GFS, c'è da murì màt!!!

Ma le carte non le posta più nessuno?

Visto che sotto le 240h ancora c'è il nulla cosmico direi che non serve....potete anche non mettere gli spaghi, tanto son solo 3/4 quelli isolati freddofili, il resto è da nulla riporto nulla da 0 a 340h
