Environmental Topics


This guide uses the definitions of weather and climate from the National Oceanic and Atmospheric Administration (NOAA). Both terms concern the "state of the atmosphere with respect to wind, temperature, cloudiness, moisture, pressure, etc." The distinction between the terms is the time factor, as defined below.

Term Definition and Example
  • The "composite or generally prevailing weather conditions of a region, throughout the year, averaged over a series of years."
    • An example is the average recorded snowfall in Washington DC for the date of January 15th for the past seventy years.
  • The atmospheric "conditions at a given point in time."
    • An example is the recorded snowfall in Washington DC for January 15, 2024.
