How many degrees Fahrenheit does the lapse rate drop for every 1,000 feet according to the standard atmosphere properties?

The lapse rate is an important concept in meteorology and aviation, referring to the rate at which temperature decreases with an increase in altitude. According to the standard atmosphere properties, the average lapse rate is approximately 3.5 degrees Fahrenheit for every 1,000 feet of elevation gain.

This value is derived from the understanding that, as a general rule in the lower atmosphere (troposphere), air temperature tends to decrease with altitude due to the thinning of the atmosphere and decreasing air pressure. The 3.5 degrees Fahrenheit rate reflects this phenomenon under standard atmospheric conditions.

Understanding the lapse rate is crucial for air traffic control and pilots, as it affects aircraft performance, weather phenomena, and decisions regarding flight paths and altitudes. Keeping track of temperature changes with altitude helps in anticipating weather conditions and maintaining safe operational procedures.
