Every year in September, the autumnal equinox occurs, signaling the start of fall and the end of summer in the northern hemisphere. The axis of the Earth is inclined. This means that depending on where the Earth is along its orbit, the Sun lights the northern or southern hemisphere more. The Sun will, however, evenly illuminate the northern and southern hemispheres twice a year. The equinoxes are those times.
When is fall?
The three basic classifications of autumn are phenological, meteorological, and astronomical.
Astronomical
The four seasons are based on astronomical equinoxes and solstices. There is some debate, nevertheless, between those who believe that the equinox or solstice marks the beginning or halfway of the season.
Meteorological
On the other hand, based on monthly average temperatures, meteorologists typically divide seasons into intervals of three whole months, with summer being the warmest and winter being the coldest. Based on this, the autumn months are typically September, October, and November for the majority of the northern hemisphere.
Phenological
Utilizing phenological markers is the third method for identifying autumn. These include a variety of ecological and biological indicators, including the shedding of tree leaves and the migration of birds to warmer regions. Since weather and climate naturally have a big impact on these events, a changing climate could cause autumn to begin earlier or later than it would according to astronomy or meteorology.
