What was the local weather like within the newest reporting interval?
The NWS local weather abstract for metro Atlanta has now been up to date with August 2024 figures.
In an article entitled What is the Difference between Climate and Weather?, the National Ocean Service describes the distinction as follows:
“Weather is what you see outdoors on any explicit day. So, for instance, it might be 75° levels and sunny or it may very well be 20° levels with heavy snow. That’s the climate.
“Climate is the average of that weather. For example, you can expect snow in the Northeast in January or for it to be hot and humid in the Southeast in July. This is climate. The climate record also includes extreme values such as record high temperatures or record amounts of rainfall. If you’ve ever heard your local weather person say “today we hit a record high for this day,” she is speaking about local weather information.
“So when we are talking about climate change, we are talking about changes in long-term averages of daily weather. In most places, weather can change from minute-to-minute, hour-to-hour, day-to-day, and season-to-season. Climate, however, is the average of weather over time and space.”
The local weather report for the Atlanta space for the earlier month exhibits how a lot departure from the common temperatures that month represents. The common temperature for a date is the common over a 30-year interval.
