Exploring spatial patterns of trends in monthly rainfall and temperature in the Philippines based on Climate Research Unit grid

Abstract

© 2018, Korean Spatial Information Society. This study assessed spatial pattern of trends in monthly rainfall and temperature in the Philippines using Climate Research Unit time series data. Based on the results, there are significant trends in monthly rainfall and temperature in the country. On the average, monthly rainfall in the country is increasing by 0.34 mm/year. In the case of monthly temperature, the average increases per year were 0.008 and 0.019 °C, for maximum and minimum temperature, respectively. In terms of proportion, larger portion of the country showed significant trends in monthly temperature (> 80%) compared to rainfall (< 10%). Shift in wettest, driest, warmest, and coldest months were also observed between the periods of 1951–1980 to 1986–2015.
