High humidity can often have a negative effect on the capacity of chemical plants and refineries that use furnaces as part of a certain processes (e.g., steam reforming, wet sulfuric acid processes). For example, because humidity reduces ambient oxygen concentrations (dry air is typically 20.9% oxygen, but at 100% relative humidity the air is ...
Osmotic absorption becomes more important during times of low water transpiration caused by lower temperatures (for example at night) or high humidity, and the reverse occurs under high temperature or low humidity. It is these processes that cause guttation and wilting, respectively. [66] [67] Root extension is vital for plant survival.

For instance, the dew point temperature of air at 20 °C (68 °F) and 80 percent relative humidity is 16 °C (61 °F). The dew point temperature falls to 9 °C (48 °F) if the relative humidity is 50 percent. [4] A related, but quite distinct, technique of obtaining atmospheric moisture is the fog fence.
4. Air Plants. Per Marino, tillandsia (AKA air plants) thrive in humidity: “As an epiphyte, the air plant grows on top of tree branches and pulls all the water it needs from the intense morning ...
[7] typically a fraction of a percent by weight when in equilibrium of air of Relative humidity 10% to 90%. This affects the rate that buildings need to dry out after construction, typical cements starting with 40-60% water content.
The return of higher humidity will not be anything out of the ordinary for the middle of summer, Dombek said. However, the uptick will mark another change in the weather pattern.
Cloud-forest conditions are hard and expensive to replicate in a glasshouse because it is necessary to maintain very high humidity. Day temperatures have to be between 70-75F while night temperatures have to be maintained between 55-60F. In most cases, sophisticated refrigeration equipment has to be used to provide night temperatures below 60F.
