The results demonstrated a noticeable spatial variability with three subregions characterized by different trends: a remarkable wet tendency prevails in the central and southern areas, while the northern areas are dominated by a remarkable dry tendency.Īguilar E, Peterson TC, Obando PR et al (2005) Changes in precipitation and temperature extremes in Central America and northern South America, 1961–2003. The principal component analysis (PCA) was applied to the SPI series computed on 24-month time scales. Furthermore, the spatial and temporal variation of dryness/wetness has been assessed by the standardized precipitation index (SPI). Although the directions of trends in annual rainfall erosivity at most stations are upward, only 6 of the 75 stations have significant trends. When it comes to rainfall erosivity, most of this province is characterized by high values of annual rainfall erosivity. Meanwhile, both of the monthly rainfall heterogeneity and the contribution of the days with the greatest rainfall show an upward trend. For precipitation extremes, most of precipitation indices suggest that both the amount and the intensity of extreme precipitation are increasing, especially the mean precipitation amount on a wet day, showing a significant positive trend. Based on daily precipitation records at 75 meteorological stations in Hunan Province, central south China, the spatial and temporal variability of precipitation indices is analyzed during 1961–2010. ![]()
