4. Exploratory Work on Teleconnections between SST and Soil Moisture
( Lettenmaier, Cavazos and Zhu )
Sea surface temperature: Extended Reconstruction of Global Sea Surface Temperature data set based on COADS data. ( ) developed by T.M. Smith and R.W. Reynolds, NCDC. The original data resolution is 2º longitude, 2 º latitude. It was interpolated into 0.5 º resolution (The ocean domain is chosen according to the Bin Yu and J.M. Wallace’s paper, 2000, J. Climate, 13, )
Soil Moisture: VIC retrospective land surface dataset ( ). The original data with 1/8 degree resolution is aggregated into 0.5 º resolution.

5. Soil Moisture Predictability by Persistence and SST PCs
The highest variance explained is more than 90%. For June, over 40% of the variance is explained over most of the study domain, including Mexico.
( Lettenmaier, Cavazos and Zhu )

6. Soil Moisture Predictions: SST & Persistence vs. Persistence Only
Introducing SST PCs benefits long-time lead predictability (of June soil moisture), but no significant benefits for less than 6-month lead time predictability.
