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 ...
Root pressure is the transverse osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves. [ 1 ] Root pressure occurs in the xylem of some vascular plants when the soil moisture level is high either at night or when transpiration is low during the daytime.
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.

Tiny hair-like structures called trichomes on the surface of leaves also can inhibit water loss by creating a high humidity environment at the surface of leaves. These are some examples of the adaptations of plants for the conservation of water that may be found on many xerophytes. Light supply
If a house is artificially humidified, by the use of a humidifier, during the winter, this can create conditions favorable to mold. Moving air may prevent mold from growing, since it has the same desiccating effect as low humidity. Mold grows best in warm temperatures, 25 to 30 °C (77 to 86 °F), although growth may occur between 0 and 35 °C ...
L.A. County will get a short break from the winds Sunday night before they pick up again Monday through Wednesday, gusting from 25-45 miles per hour, officials said.
