  abstract: This dissertation focuses on examining the relationship between antecedent soil moisture and summer precipitation in the U.S. Great Plains (GP). The influence of Nino sea surface temperatures (SSTs) on summer precipitation has also been investigated to compare their relative contributions to those from local moisture recycling. Both observational data and model simulations have been used to investigate how and why soil moisture can affect subsequent summer precipitation in the GP. Observational analysis indicates that spring (May 1st) soil moisture is significantly correlated with summer precipitation only during periods when Nino SSTs are not strongly correlated with summer precipitation (e.g. 1925-1936). During periods when Nino SSTs are strongly correlated with summer precipitation (e.g. 1940-1970), spring soil moisture is not a good predictor of summer precipitation in the GP. The periods of strong correlation between Nino SSTs and summer precipitation are associated with strong SST persistence. This study suggests that both local soil moisture and remote SST anomalies (deviation from SST climatology) influence summer precipitation in the GP. The soil moisture anomalies are of greatest importance during years when Nino SST persistence is low. Model results have demonstrated that there are significant differences in precipitation response to soil moisture anomalies depending on their sign (+/-), timing and persistence. The influence of dry soil moisture anomalies on subsequent precipitation tends to last longer than wet soil moisture anomalies when initialized on May 1st. Dry soils can influence summer precipitation in the subsequent 2-3 months. However, the precipitation response to wet soil moisture anomalies is faster and greater in magnitude than the response to dry soil moisture anomalies. Persistent soil moisture anomalies that are sustained for an entire month produced larger precipitation changes than soil moisture anomalies only applied on the first day …
