Summer aridity in the United States: Response to mid-Holocene changes in insolation and sea surface temperature

We examine the response of summer precipitation to mid‐Holocene insolation forcing and insolation‐induced changes in sea surface temperature. Using a high‐resolution nested climate modeling system, we find that mid‐Holocene insolation forcing results in drier‐than‐present conditions over the central continental United States (U.S.) and northern Rocky Mountains, as well as wetter‐than‐present conditions over the Atlantic seaboard and northwestern...
