PRISM normals data and the change in temperature or precipitation from MACA data are combined to generate predicted future annual and seasonal temperature and precipitation averages at the county level for the nation. We used the Multivariate Adaptive Constructed Analogs (MACA) statistically downscaled data to generate a period change analysis (1971-2000) vs. (2040-2069) of minimum temperature, maximum temperature, and change in precipitation upscaled to the county level. This is a list of cities by average temperature (monthly and yearly). Travel and vacation weather information for your holiday journey from Weatherbase. (2008). Product Filters: Product Type Ranks Anomalies Abs. Scenario: RCP 8.5. Time period: 2040-2069

Values % of Normal. Average change in temperature and precipitation values for the year and four seasons are summarized at the county level. Base data used - We use the 30 year normal data from the PRISM Climate Group for the 1971 to 2000 time period to represent the historic base temperature and precipitation. Not all products are available for all dates and time periods.

Information is based on 1971 to 2000 normals.     Time period: 1971 – 2000. View high, low and average temperatures within an area and the amount of cooling required (CDD), amount of heating required (HDD) and amount of rain in inches. Monthly and daily averages and yearly totals. This is a monthly 30-year normal dataset covering the conterminous US, averaged from 1971-2000. This is a collaborative website hosted under guidelines described in ARS Policy and Procedures #030 (dated 11/13/2013), Section 4-14. National temperature and precipitation maps are available from February 2001 to September 2020. Parameter Temp Precip. The change (1971 – 2000) vs. (2040 – 2069) in minimum and maximum temperature and precipitation for annual and seasonal timesteps for RCP8.5 was downloaded from MACA. These data are provided for both seasonal and annual time periods. PRISM normals data and the change in temperature or precipitation from MACA data are combined to generate predicted future annual and seasonal temperature and precipitation averages at the county level for the nation. Data are intended to provide a general estimate of broad seasonal changes in temperature and precipitation at the county scale to aid planning and management amid uncertainty. Use the Climate Data lookup to find climate information by ZIP Code. The temperatures listed … A description of the PRISM model, an uncertainty analysis and methods for creating the 1971-2000 normal data are described by Daly et al. List of countries - Global Climate data - Climate information and average monthly temperature, humidity, rainfall, snowfall, daylight, sunshine, UV index, and sea temperature for all countries in the world. Climate Change and the Carbon Cycle – Curriculum Unit for 9-12 Grade Students, Climate Change and the Water Cycle - 10-Hour Curriculum Unit for 6-12 Grade Students, The Effects of Climate Change on Agricultural Systems - 5-Hour Curriculum Unit for 6-12 Grade Students, Multivariate Adaptive Constructed Analogs, Southwest Regional Climate Hub and California Subsidiary Hub Assessment of Climate Change Vulnerability and Adaptation and Mitigation Strategies. ArcGIS was used to generate average values for minimum and maximum temperature and precipitation at the county level. Average yearly temperature is calculated by averaging the minimum and maximum daily temperatures in the country, averaged for the years 1961–1990, based on gridded climatologies from the Climatic Research Unit elaborated in 2011.

Future data used - We use the Multivariate Adaptive Constructed Analogs (MACA) (Abatzoglou and Brown 2012) downscaled temperature and precipitations projections from 20 general circulation models of the Coupled Model Inter-comparison Project 5 (CMIP5) for the future time period (2040-2069) and the Representative Concentration Pathway 8.5 (RCP 8.5). Average change in temperature and precipitation values for the year and four seasons are summarized at the county level. Region CONUS Alaska. We downloaded monthly PRISM data and calculated the mean minimum temperature, maximum temperature, and precipitation on a seasonal and annual basis.
