ABSTRACT

This paper demonstrates a choropleth map to show spatio-temporal trends of global precipitation using the GIS/RS program Idrisi. While both annual mean and seasonality of the Global Precipitation Climatology Project (GPCP) data for different time periods are mapped in a single map form, two maps are generated to indicate linear and monotonic trends of global precipitation change. It appears evident that global patterns of precipitation had changed substantially between 1979 and 2006, where the patterns are mostly monotonic than linear. In other words, the trends of monotonic increase or decrease, which do not necessarily have to be a linear trend, are more dominant than the linear trends. This cartographic scheme turns out to be useful in terms of visualizing spatio-temporal information in a concise manner and categorizing areas that experience distinct patterns of climate change.
