<b>Sounding </b>describes a plot of the vertical profile of temperature and dew point (and often winds) above a fixed location. 
Soundings are used extensively in severe weather forecasting, e.g., to determine instability, locate temperature inversions, 
measure the strength of the <b>cap</b> (capping inversion), obtain the convective temperature, 
<a href="http://www.weatheronline.co.uk/feature/cc270503.htm" target="_top"><b>CAPE</b></a> (Convective Available Potential Energy) 
and <b>CIN </b>(Convective Inhibition). 
<br><br>
Horizontal lines represent height in pressure coordinates (millibars or hPa); diagonal lines represent temperature. 
Heavy solid lines show the vertical profile of modeled temperature (red) and 
<a href="http://www.weatheronline.co.uk/feature/wf261001.htm" target="_top"><b>dew point</b></a> (blue). 
The grey line shows the temperature of a parcel of surface air and how its temperature would change if it would be lifted.
