Importance of climate-weather interface ◦ Seasonal forecasting Agriculture Water resource management
Climate Data – Monthly Indexes ◦ PNA,PDO,ENSO,NAO,AO ◦ Climate Prediction Center (NOAA) Temporal Coverage – 1955 to present Temporal Resolution - Monthly Precipitation Data ◦ NOAA's PRECipitation REConstruction Dataset (PREC) Temporal Coverage – 1948 to present Temporal Resolution - Monthly Spatial Coverage – Global Spatial Resolution – 2.5° latitude x 2.5° longitude
Precipitation data split into six regional datasets which cover the Northwest, Southwest, North-central, South-central, Northeast, and Southeast United States Grid points in each region are summed to obtain a single monthly precipitation anomaly for each region

The largest correlations were found during the winter months (DJF) LocationPNAPDOSOINino-4Nino-3NAOAO Northwest Southwest North-Central South-Central Northeast Southeast The following analyses will cover the relationship between Nino-3 and precipitation over the North-Central United States
Some significant correlations between precipitation and teleconnection patterns Better spatial resolution of the analysis might improve results ◦ Perform correlations and regressions at each gridpoint
