Summary
This 1992 methodological paper presents the seasonal and temporal precipitation concentration index as a tool for characterising monthly rainfall distribution patterns in Spain. The index quantifies the degree to which precipitation is concentrated in particular months or seasons, providing a standardised metric for comparing rainfall seasonality across regions. Such indices are relevant to soil erosion risk assessment and water resource management in Mediterranean and semi-arid climates.
Regional applicability
Spain's Mediterranean and semi-arid climates differ significantly from United Kingdom conditions, which experience more distributed year-round precipitation. However, the methodological framework may have transferable value for UK climate classification and regional rainfall characterisation studies, particularly in applying standardised metrics to variable UK precipitation patterns.
Key measures
Precipitation concentration index (PCI); seasonal precipitation distribution; temporal rainfall patterns; monthly rainfall variation
Outcomes reported
The study developed and applied seasonal and temporal precipitation concentration indices to characterise monthly rainfall distribution patterns across Spain. This methodology enables quantification of rainfall seasonality and concentration, which has implications for water availability and erosion risk assessment.
