Why Odors Get Worse as Weather Warms
Are you smelling what I’m smelling? There are any number of situations during which you are likely to notice that odors worsen as temperatures rise. Whether you are driving by your local landfill in the summer or noticing your trash can when you open the door to your hot garage, these pungent smells are hard to miss.
Many industrial processes have odor problems on a much larger scale, which need to be managed for health and safety. Understanding why odors get worse as the weather warms can shed some light on understanding how to manage odors at places like wastewater treatment facilities.
When Temperatures Increase, Gases Are Energized
Rising temperatures increase the amount of energy available for odor-causing molecules. These molecules, in the form of a liquid or solid, require additional energy to transition into the gas phase. As the rise in temperature provides that energy, liquids or solids become gases and emit stronger odors. To make matters worse, heat also makes odor-causing bacteria grow faster.
Hot and Humid Air Causes Odors to Linger
Heat is often accompanied by humidity, which can be an aggravating factor when it comes to odor. Humidity describes the condition of vaporized water being trapped in the air. This humid air is heavy, so it also has the effect of trapping odors. Because the odor-causing molecules linger and are concentrated they produce a much more intense smell.
Weather and the Role of Temperature Inversions
Beyond temperature and humidity, the weather itself can play a role in the intensity of odor. On a clear cold night with high pressure, or an evening when a warm front is moving in, temperature inversion occurs. This inversion creates a warm layer of air just above a colder layer of air. Since the cold air is heavy and dense, the warm layer confines elements such as smoke, fog, and especially odors.
