Herbstanfang Wann ist Herbst? Wann ist Herbstanfang 2016
On the question of the beginning of autumn there as so often several answers: The answer can depending on what you want to know, so vary.
Firstly, there is the official start of autumn. This is often referred to as calendrical beginning of autumn, although he did not strictly follows the calendar and astronomical actually early fall would be called. He directed namely, in principle, directly after the position of the earth to the sun and is therefore relatively reliable.
Then there is the phenological Autumn Equinox, which depends on phenomena in nature - for example, after flowering of the autumn crocus.
And then there are also the for statistical purposes arbitrarily determined meteorological start of autumn always to 01 September.
Of course there are also the sensed early autumn - ie the time when one individually has the feeling "Now autumn". That Herbstgefühl 'often arises also with phenomena in nature - so to speak reasonably parallel to the phenological autumn beginning. Very obvious and therefore also very popular, for example, the discoloration of the leaves. For many people, colorful foliage is the direct indicator that now the summer is finally over and the autumn has begun. But one after anonther:
Astronomical: When is the official / calendrical beginning of autumn 2016?
Calendrical beginning of fall 2016 on September 22,
Still +0 days / Today the beginning of autumn 2016th
First briefly on the relationship between the calendar and astronomy. Basically, the man-made calendar follows astronomical processes. Astronomy is the beginning of autumn, as well as the beginning of spring, determined by the so-called day-and-night are equal or the equinox. These are the two days in the year when day and night are of equal length. Autumn ends with the winter solstice, which marks the beginning of winter.
During the winter months the nights are well known, longer than the days. During summer months, the days, however, are longer than the nights. On the day of the day and night are equally long, but the time between sunrise and sunset (day) is as long as the period between sunset and sunrise (night).
The first day-and-night match of the year, or even primary-day-and-night-same, marked on the northern hemisphere the beginning of spring. The secondary-day-and-night-Same marked accordingly the time of the year, on the day and night for the second time are of equal length. In the northern hemisphere begins the autumn, in the southern hemisphere begins the spring.
The timing of the secondary-day and night-same is not always on the same day - The calendrical Autumn Equinox may vary. Most of calendrical and astronomical Autumn Equinox is on 22 September or 23 September. Here the effective dates of the coming years:

When is the fall in meteorological terms?
In meteorology, it is relatively simple: you have assigned each season arbitrary three months. Accordingly, the Meteorological autumn begins each year on the northern hemisphere with the 01 September and ends on 30 November.
Spring months of March, April, May
Summer months: June, July, August
Autumn months: September, October, November
Winter months of December, January, February
The "meteorological Autumn Equinox" was established by organizational unit of the United Nations UN - World Meteorological Organization (World Meteorological Organization, WMO). The arbitrary division of the year makes it easier to collect weather data for longer periods and to compare.

The third type, to determine the beginning of fall, is the phenological method. Man divided basically in plant and animal phenomena-phenomena. This means that the beginning of the fall is determined by observation of nature and the phenomena that can be observed in nature.
It is virtually a IST contemplation of nature. When plants observation thus passing the beginning of autumn right on the state of development of various plants. Accordingly, it is knowledge and not forecasts - the data can therefore always only be subsequently evaluated and made available.
Phenological autumn in Central Europe is divided into the following three phases:
early fall
Flowering of the autumn crocus, incipient maturity of black elder, cornel and hazel, crop of pears and plums
Vollherbst
Many trees change their leaves, including oak, ash, chestnut, beech, and "Wild Wine". Chestnuts and acorns fall from the tree.
late autumn
Many trees shed their leaves, the winter crops to go
The phenological autumn beginning therefore depends on the weather and the microclimate around. It may therefore vary by region - depending on geographical latitude and longitude, depending on height, depending on the microclimate. Often, the phenological autumn beginning place for example in cities somewhat later rather than in the countryside - later in the south than in the north - and in the valleys later than on the mountains.
