A relationship between temperature and precipitation over the contiguous Bandung city, Indonesia

Abstract

Temperature and precipitation are important measurements for explaining the climate and can have wide-ranging effects on human life and ecosystems. A warming climate tends to increase precipitation in many areas. Therefore, studying the relationship between temperature and precipitation is crucial for providing information precipitation prediction in many areas. The information on the relationship between precipitation and temperature will be very useful for a lot of fields such as ecological analysis, agriculture, and business. The correlation between monthly total precipitation and monthly mean temperature over the 30-year period from 1970 to 2000 using WorldClim global database data for Bandung city at ~ 1 km2 resolution was calculated and analyzed. Geographically weighted regression has been used to estimate regression coefficients of mean temperature on precipitation which allow varying over space and time. Regions of both positive and negative precipitation-temperature correlations were found which indicates that warm summers tended to be dryer. This particularly true in the northern regions of Bandung.
