They look back to datasets spanning decades, and use techniques to make sure data represent current conditions, such as, say, increases in extreme weather. This preliminary set of maps from NOAA show the change in maximum temperature in the peak of each season between the old climate normals (1981-2010) and the new climate normals (1991-2020). Most of the U.S. was warmer, and the eastern two-thirds of the contiguous U.S. was wetter, from 19912020 than the previous normals period, 19812010.

Monthly: 1981-2010 normals At least some of that wetness relative to the 20th-century average is linked to the overall climate warming and wetting of the atmosphere thats occurred as rising temperatures cause more water to evaporate from the ocean and land surface. Heat maps and matching satellite images presented with a slider, so that readers can get a sense of how and why each city experiences such a wide range of temperatures on a hot summer day. For the Atlantic basin (the Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico), the chart is based on data from the 77-year period from 1944 to 2020 (starting at the beginning of the aircraft reconnaissance era) but normalized to 100 years. Some are well known metrics like heating and cooling degree days, growing season length for various temperature thresholds, numbers of days with precipitation or with temperatures below freezing, etc. However, station-based temperature comparisons based on this same set of station normals are not reliable, because the homogenization process that removes artificial discontinuities (station moves, instrument changes, etc.) Climate Normals: An Overview. NOAA's Geoplatform provides geospatial data, maps, and analytics in support of NOAA's mission through a GIS application using Esri's ArcGIS Online. ), and recommends an update each decade, in part to incorporate newer weather stations. 40.24N 111.64W (Elev.

Climate Normals period from 1901-1930 (upper left) to 1991-2020 (lower right). Many agencies, including the NOAA Climate Prediction Center, develop their own averages and change base periods for specific applications and/or internal use. Unlike complex station climate normals, monthly gridded normals are simple averages of the maximum temperature, minimum temperature, mean temperature, and precipitation totals for each month of the year.

Suite 250 A team of NCEI researchers spent considerable time and effort improving and automating these processes, particularly for daily and hourly normals. For longer term climate change study comparisons, we also produced the 20th Century Baseline, a set of averages from 19012000. The data set reflects a new normal that takes the most recent 30 years of climate change-influenced weather and climate conditions into account. Honolulu, HI 96822 Fire Weather (Note that for Figures 2a and 2d, the average for individual reporting stations varies greatly because of the state's large elevation range.)
