The characteristics and the importance of the stratosphere layer

The stratosphere layer

The stratosphere layer is the second layer of the atmospheric envelope , It is called the ozonic atmospheric envelope , The atmospheric pressure in the stratosphere layer decreases as we go up until it becomes 1 mb at its top ( 0.001 of the normal atmospheric pressure at the sea level ) .

The stratosphere layer

The stratosphere extends from the tropopause to the stratopause

The stratosphere layer extends from the tropopause ( at a height of 13 km above the sea level ) to the stratopause ( at a height of 50 km above the sea level )  , The thickness of the stratosphere is 37 kilometers .

The temperature in the stratosphere layer increases gradually from ( – 60 degree Celsius ) , at the lower part until it reaches ( 0 degree Celsius ) at the top of the layer .

The temperature increases gradually due to the absorption of the ultraviolet rays  that emitted from the Sun by the ozone layer which is present at the upper part of  the stratosphere  layer .

The stratosphere layer contains the most of the ozone gas which found in the atmospheric envelope at the height 20 t0 40 km above the sea level . So , The stratosphere layer is called the ozonic atmospheric envelope .

The lower part of the stratosphere layer does not contain clouds or weather disturbances , and the air movement is horizontally . So the pilots prefer to fly their planes in the stratosphere layer .

So , the stratosphere layer is important for man’s life as it contains the ozone layer which absorbs the harmful ultraviolet radiations which emitted from the Sun , and also it is convenient for flying of the planes .
