Gold Bar air quality reports

Wind direction is reported according to the direction from which it originates – for example, a north wind blows from north to south. Winds are usually reported using either cardinal directions, or degrees of direction.

Air temperature affects the movement of air. Different temperatures between two locations create a difference in air pressure. The atmosphere tries to equalize the air pressure, forming wind.

Humidity is the concentration of water vapor present in the air. Relative humidity is the ratio of a present state of humidity relative to a maximum humidity given the same temperature.

Barometric pressure is the air pressure, as measured within the atmosphere. It is quantified by the hydrostatic pressure caused by the weight of an air column above a measurement point. It is impacted by the planetary rotation and local effects such as, variations in temperature, density, air composition etc. Wind is generated by air movement from high to low pressure areas.
