Recent advances in spatial climate modeling make it possible to view animated monthly maps of Alaska’s temperature and precipitation. Monthly weather station data and other point measurements (1961-1990 Normals) were spatially distributed across Alaska with the PRISM model, developed at the Spatial Climate Analysis Service, Oregon State University.
The maps presented here were made from the previously created PRISM grids using a Geographic Information System (GIS). Separate animations are available for temperature and precipitation. The animations reveal patterns in both time and space related to the seasons, latitude, elevation, coastal effects, rain shadows, and other environmental parameters in a region of climatic extremes.
