Autumn is one of the four cold-temperate seasons that marks the conversion of summer to winter. Autumn season can be experienced usually in September in the Northern Hemisphere, and in March in the Southern Hemisphere. Another sign to mark the arrival of Autumn is when the night becomes noticeably earlier.
The equinoxes might be expected to be in the midst of their respective seasons, but a slowdown in the temperature means that seasons appear little late than the dates calculated from a purely astronomical perspective. The actual slowdown varies with the region.
Meteorologists use a definition for the seasons based on months, with autumn being experienced in September, October, and November in the northern hemisphere, and in March, April, and May in the southern hemisphere.
The first day of Autumn in the United States and in the northern hemisphere is the day when the Sun crosses the ethereal equator moving southward. This scrumptious day is known as the Autumnal Equinox.
The descent of the Sun on the autumnal equinox is 0? 00'. The day and night on the day of the autumnal equinox are nearly the same amounts of time. The United States has nearly 12 hours of daylight on this day.
The autumn season is also known as fall. It traditionally begins in the U.S with the Labor Day Holiday at the start of September, and extends till the end of November celebrating the Thanksgiving Day holiday. Temperatures in the autumn normally range between 50 and 60 degree Fahrenheit in most places of the U.S.
During the autumn season, leaves change their color from green to yellow, then to orange, and then to red before they start to fall and touch the ground. The best months to experience autumn are September and October in the U.S.
Autumn is a quite and pleasant season in most of the U.S. The northern states of U.S generally brings warm sunny days with cool nights. The leaves of plants and trees begin to change their color, and produces a magnificent view for a few short week.
Autumn means an end of the super-hot summer and onset of pleasant temperatures. The land and hills are filled with trees full of bright yellow and orange leaves during the Autumn season.
