•Cold (warm) SST over eastern and western N Pacific and warm (cold) SST over central N Pacific induce wet (dry) summers (Ting)
•Tropical Pacific SST vary between wet and dry events (Ting)
•Extratropical SST influence central and eastern US precipitation (Ting)
•Tropical SSTs influence Northern Great Plains precipitation (Ting)
•Conditions for drought à cold SSTAs in tropical Pacific in winter and neutral ENSO summer w/ warm SSTAs over west coast of US and in N. Atlantic (Mo, 2008)
•Conditions for wet spells à warm ENSO winter pattern w/ positive SSTAs in tropical Pacific and negative SSTAs in N. Atlantic…weakening of warm ENSO in summer w/ weaker SSTAs in eastern Pacific (Mo, 2008)
•During 1930s, yearly SST variations played at most secondary role in drought conditions (Schubert)
•SSTA affect in 1988 drought was also small (Mo, 1990)
•Summertime cold SSTAs suppressed rainfall over Great Plains (Schubert)
