According to the article, there are three different methods of defining seasons in the Northern Hemisphere. While each method has its own criteria, they all provide insight into the changes that occur throughout the year.
1. Solar Seasons
One way to define seasons is based on the length of daylight throughout the year. This method takes into account the amount of sunlight a specific region receives and how it changes over time. The start and end of solar seasons may slightly vary from year to year.
2. Astronomical Seasons
Another method relies on the Earth’s position relative to the Sun. These seasons are called astronomical seasons and are closely related to solstices and equinoxes. For example, the winter solstice marks the shortest day and longest night of the year in the Northern Hemisphere. After the solstice, the position of sunrise and sunset gradually shifts northward, resulting in longer days and more sunlight.
3. Meteorological Seasons
The third method of defining seasons is based on the calendar and the average temperature throughout the year. Meteorological seasons divide the year into four equal parts, with each season lasting three months. In this system, winter begins on December 1st and lasts until the end of February.
Although each method provides a different perspective on the changing seasons, they all provide valuable information about the natural rhythms in the Northern Hemisphere. Regardless of the amount of daylight, the position of the sun, or the average temperature, each factor contributes to our understanding and experience of the seasons.
