Lines on the skew-T Dry Adiabats

Dry adiabats on a skew-T

Dry adiabats represent lines of constant potential temperature. On the skew-T diagram, dry adiabats are the slightly-curved, solid lines sloping from the lower right to upper left. They indicate the rate of temperature change in a parcel of dry air rising or descending adiabatically, i.e., with no loss or gain of heat by the parcel. The dry adiabat for each multiple of 10°C shares a label with the isotherms, with the Celsius temperature value of its point of intersection with the 1000-hPa isobar.
