Spatial and Temporal Variations in Rainfall: Quirino Province

Abstract ―​

In order to adequately prepare decision makers for their diverse planning processes, it is necessary to comprehend historical and contemporary patterns of rainfall.Using rainfall data from seven (7) rain gauges in nearby provinces like Aurora and Nueva Vizcaya, the spatial analysis of rainfall in the Province of Quirino was conducted. Regression analysis and correlation analysis were used to assess spatial variation. The results of the significance test and annual correlation analysis showed that 12 pairs of stations had strong correlations. The months of May through December mark the start of the rainy season, whereas January marks the start of the dry period and concludes in April.
