The first usage of a compass recorded in Western Europe and Persia occurred around the early 13th century.

This results in an increase of 38.5Â°F. Adding the 38.5Â°F increase to the original 12,000 feet temperature of 23Â°F, the parcel has a new temperature of 61.5Â°F. AVERAGE ADIABATIC LAPSE RATE.The average lapse rate lies between the dry adiabatic and the moist adiabatic at about 3.3Â°F per 1,000 feet.SUPERADIABATIC LAPSE RATE.The superadiabatic lapse rate is a decrease in temperature of more than 5 1/2Â°F per 1,000 feet and less than 15Â°F per 1,000 feet.AUTOCONVECTIVE LAPSE RATE.The autoconvective lapse rate is the decrease of more than 15Â°F per 1,000 feet.UPERADIABATIC LAPSE RATE.The superadiabatic lapse rate is a decrease in temperature of more than 5 1/2Â°F per 1,000 feet and less than 15Â°F per 1,000 feet. AUTOCONVECTIVE LAPSE RATE.The autoconvective lapse rate is the decrease of more than 15Â°F per 1,000 feet.
