The delights of the Autumn season

Autumn is one of the most loved times of year, mainly due to the array of colours that our trees turn during this period along with it being the time of harvest. Sitting in your house all snuggled up with a blanket on the sofa with your heating turned on and in good working order thanks to http://www.hprservicesltd.com/gloucester-boilers/boiler-service-gloucester/ who conduct Boiler servicing in Gloucester, is one of the main reasons people like this time of year.

Autumn begins on the 22nd or 23rd September depending on when the Autumn equinox occurs – this is governed by the planet’s orbit around the Sun. This very occasionally occurs on the 24th September as the Gregorian calendar (which was adopted in 1582) is not perfectly in sync with the obit of the sun. This happened in 1931 and will occur again in 2303. As this date can change each year meteorologists developed their own start date for Autumn in order keep accurate records. The meteorological start of Autumn is 1st September each year. Equinox is a Latin word that means – equi (equal) and nox (night). It is used to define the period of time when the day-time and night-time (in terms of light) are of equal length. The Spring Equinox is what signals the end of the equal timings.

 

Watching the colours of the leaves on the tress tun golden yellow, orange and red is a sight that many people enjoy, and it begins once the daylight time starts to decrease. The scientific reason for this I that as the daylight decreases there is less light available for the plants to use in photosynthesis, this means that the trees reduce their food production and the amount of chlorophyll produced creating the vivid colours and the leaves ultimately falling from the trees.  The reduction of chlorophyll in the leaves means that other chemicals increase such as carotenoids, flavonoids and anthocyanins – these are the same chemicals that produce the colour in an egg yolk and in carrots.

Greek mythology states that the starting of Autumn was caused by Demeter (she was the Goddess of the Harvest) when her daughter Persephone was kidnapped by Hades and forced to be the Queen of the Underworld. As a result of her pain at losing her daughter, Demeter caused all the leaves on the trees and crops to die and did not reverse this until her daughter was returned – this is what we now know as Spring.
