Emagram

Emagramm the (energy -mass graph ) is a graph of temperature and humidity. Here, the temperature and moisture content of the atmosphere in different heights are displayed vertically. The horizontal axis (X -axis) in each case describes the temperature in degrees Celsius, and the vertical axis (Y- axis) is the height in meters and hPa Since temperature - and moisture content are shown vertically in this diagram type, the auxiliary lines ( lines of equal temperature are or isotherm ) presented to the temperature axis (X- axis) by 45 degrees to the right inclined ( in conventional charts rectangular). This is necessary because under normal conditions the air with increasing altitude is colder and the resulting temperature difference thus be seen again.

The Emagramm is often used in aviation (especially gliding ) in order to predict the thermodynamic conditions (eg, updrafts, cloud base, inversions ) can. To understand Emagramme, is associated with a certain initial effort, but who is familiar with it, can win a lot of information from it.
