If a meteorologist wants to calculate the average high temperature for "Summer 2023," using the astronomical definition would require data from June 21 to September 23. To compare this with "Summer 2024," they would have to adjust for the specific time of the solstice each year. Using the meteorological definition, they simply pull data from June 1 to August 31 for both years. The result is a clean, "apples-to-apples" comparison that accurately represents the hottest quarter of the year.
are a system of dividing the year into four consistent three-month periods based on the annual temperature cycle and the civil calendar. Unlike astronomical seasons , which are dictated by the Earth's position relative to the sun (solstices and equinoxes), meteorological seasons follow the same dates every year: March 1 (Spring), June 1 (Summer), September 1 (Autumn), and December 1 (Winter). Key Differences Between Systems meteorological seasons
Seasons are periods of the year distinguished by specific weather conditions and daylight hours. For millennia, societies have tracked the passage of time using the Earth's orbit around the Sun. This method, known as the , relies on the solstices and equinoxes to mark the beginning and end of seasons. However, for meteorologists and climatologists, the astronomical calendar presents significant logistical challenges regarding data comparison and weather prediction. If a meteorologist wants to calculate the average
