Decoding the Seasonal Shift: Unraveling the Early Onset of Meteorological Seasons in Contrast to Astronomical Seasons
AstronomyWhy do meteorological seasons begin earlier than astronomical seasons? Meteorological Seasons: A Practical Approach to Weather Patterns Meteorological seasons are a commonly used framework for dividing the year into distinct periods based on weather patterns. These seasons, which include spring, summer, fall, and winter, are typically defined by specific calendar dates that differ from astronomical
