Soil Moisture Feedbacks on PrecipitationCollaborators: None Funding: DOE NICCR Publications: Methods: Using a statistical method of lagged covariances, following the work of Frankignoul for ocean-atmosphere interactions and Notaro/Liu for vegetation-atmosphere interactions, we investigated hotspots of soil moisture feedback on precipitation in the IPCC AR4 global climate models. Key finding: During the NH summer, the key hotspots of soil moisture feedback on precipitation are found across North Africa, northern South America, central US, northern India, and Eurasia. The hotspots agree well with the findings of GLACE. |

Regions of significant forcing of soil moisture on monthly precipitation during the Northern Hemisphere summer based on IPCC AR4 global climate models. The statistical method uses lagged covariances and results in similar findings to the GLACE experiments. | |
