arabian sea sst*: Based on average sea surface temperature of northwest Arabian Sea during January and February. Positively correlated: above normal SST means above normal monsoon.
eurasian snow cover: Based on Eurasian snow cover in December. Negatively correlated: more snow cover means less rainfall.
northwest europe temperature: Based on average mean temperatures during January in five stations over northwest Europe. Positively correlated.
south indian ocean sst: Based on difference between SST over southeast Indian Ocean and southwest Indian Ocean during March. Positively correlated.
east asian pressure: Derived from average surface pressure in February and March over east Asia. Positively correlated.
europe pressure gradient: Based on mean sea level pressure anomalies between northwest Europe and southwest Europe. Positively correlated.
50 h P a ** wind pattern during winter: Derived by measuring the longitudinal length of troughs and ridges at 50 hPa (20-25 kilometre altitude) over northern hemisphere in winter. Negatively correlated.
