The Role of Irrigation on Precipitation in The Great Plains USA
ISBN-13: 9783639144390 / Angielski / Miękka / 2009 / 276 str.
This book examines the relationship between irrigation and precipitation. The relationship is explored using the Palmer Drought Severity Index (PDSI) as a proxy for irrigation use, the Spatial Synoptic Classification (SSC) as a means of classifying surface air mass type, and the use of five atmospheric flow types characterizing the synoptic flow pattern. Scenarios, at each irrigated region, involving PDSI and either air mass type or flow type were tested using both parametric and non parametric procedures. This approach yields results according to flow type and air mass type at times when irrigation was likely or not likely to be used. Although many spatial results are significant, irrigation is only a minor contributor to precipitation. The most significant irrigation impacts are found on days when the synoptic pattern supports uplift and irrigation is a further agent of atmospheric destabilization. Irrigation is a relatively trivial factor inducing precipitation on stable days. Temporal results mirror the spatial results. More precipitation was observed at each region when irrigation use was higher or irrigation efficiency was lower.
