Extremes and averages in contiguous U.S. climate : graphs of 100 years of NOAA contiguous U.S. climate data (2018 edition)
Tisdale, Bob
This book presents graphs of NOAA climate data for each of the 9 NOAA Climate Regions of the Contiguous United States, for the Contiguous United States as a whole, and for each of the 48 contiguous United States individually. More specifically, for the 100-year period of 1919 to 2018, this book presents time-series comparison graphs, along with their linear trends, of the highest of the monthly highs per year and the lowest of the monthly lows per year-the extremes-and also the averages per year for NOAA: - Precipitation (PCP) data (presented in inches), - Palmer Drought Severity Index (PDSI) data, and - Near-surface air temperature (TMAX, TAVG, & TMIN) data (presented in degrees Fahrenheit)... ...for each of the Contiguous United States as a whole, for the 9 NOAA U.S. Climate Regions, and for each of the 48 (contiguous) States individually. The data are presented in their observed forms (or calculated form in the case of the drought data), not as anomalies. The extremes and averages were extracted by MS EXCEL from NOAA monthly data from January 1919 to December 2018. The book also includes a presentation of the adjustments NOAA has made to the average temperature (TAVG) data (before and after the adjustments) for the contiguous United States and for each of the 9 NOAA climate regions. Additionally, there are comparison graphs of the annual cycles in near-surface air temperatures, based on 30-year averages of the monthly values-the first 30 years of that 100 year period (1919-1948) versus its last 30 years (1989-2018)-for each of the temperature metrics. These are provided to show readers how the annual cycles in surface temperatures (based on average monthly temperatures) have changed between those two time periods. These comparison graphs of the annual temperature cycles are provided for each state, each region and for the Contiguous U.S. as a whole. After the explanations in the introduction, the graphs are presented without comment from the author.</p>
