An Analysis of the Spatiotemporal Variation in Wind Erosion–Climate Erosion Force in the Ningxia Region and Its Driving Factors

Wind erosion is one of the major meteorological hazards in Ningxia, and climate change has caused changes wind erosion–climatic activity recent years. This study uses factor (C) proposed by Food Agriculture Organization United Nations to assess impact on erosion–climate erosion, results show that (1) distribution degree Ningxia region central > northern southern. Seasonally, it higher spring winter, lower summer autumn. (2) Climate more influence spring, autumn less summer. (3) The center gravity mainly located at junction migrates through four migration stages—northeast–southwest–northeast–southwest—on annual scale, stages—northwest–northeast–southeast—on seasonal monthly scales. rate cold season greater than warm season. (4) index influenced sunshine hours, average temperature, humidity, speed total precipitation, spatial temporal variability, among which most sensitive speed. (5) indices are positively correlated with NAO, AO, PDO SOI indices, negatively MEI ENSO there resonance cycles different time
