THE EFFECTS OF DIURNAL TEMPERATURE-CYCLING
Diurnal temperature-cycling is the fluctuation in temperature that occurs throughout a day; or, more specifically, throughout a 24-hour period. As the day wears on, temperatures rise steadily, beginning just after dawn, and then cool, starting in the late afternoon and continuing through the night. Generally speaking, diurnal temperature-cycling causes the air inside of sealed enclosures, such as containers used for shipping and storage, to expand and contract, creating pressure and vacuum respectively. As a result, the expanding air pushes out against an enclosure’s walls (pressure) during the day when the atmospheric temperatures are warmer, and pulls against those walls (vacuum) during the night when temperatures are cooler. In many situations, this is a problem.
