Pressure : Current and History

This weather station has a pressure graph that tracks and displays the barometric pressure 12 hours ago as well as the current barometric pressure. Additionally, the graph will automatically display the “FALLING”, “STEADY” OR “RISING” icon and a curve to represent the rate of change over the previous 12 hour time period.

Atmospheric Pressure

Atmospheric Pressure is defined as the pressure at any location on the Earth, caused by the weight of the column of air above it. At sea level, atmospheric pressure has an average value of one atmosphere and gradually decreases as altitude increases. Also called barometric pressure.

The weight of the atmosphere that envelopes Earth exerts pressure on all points of the planet's surface. Meteorologists use barometers to measure this atmospheric pressure (also called barometric pressure). At sea level the atmospheric pressure is approximately 1 kilogram per square centimeter (14.7 pounds per square inch), which will cause a column of mercury in a mercury barometer to rise 760 millimeters (30.4 inches). Variations in the atmospheric pressure greatly affect the weather. Low pressure generally brings rain. In areas of low air pressure, the air is less dense and relatively warm, which causes it to rise. The expanding and rising air naturally cools, and the water vapor in the air condenses, forming clouds and the drops that fall as rain. In high pressure areas, the air is dense and relatively cool, which causes it to sink. The water vapor in the sinking air doesnʼt condense, resulting in clear skies.

USE

Daily High & Low

The daily high and low records are displayed for the indoor and outdoor temperature and humidity. These records ar cleared automatically every day at midnight.

Wireless Signal Reception Icons

The display unit has a signal reception icon near the outdoor temperature display area. If there are a low number of “bars” present, you may experience no temperature display ( “- -” ) or inacurracy. In either case, you may need to relocate one or both of the units. If most or all 4 of the bars are present, wireless reception is good and no action is required.

Forecast Icon

This feature gives you the predicted weather forecast for the next 12 to 24 hours based on an advanced algorithm that includes barometric pressure and temperature. This weather station will provide the most accurate forecast that a single station weather instrument can provide.

14 Day Learning Mode

This weather station has a patented “fourteen day learning mode” calibration process. During this learning mode the weather station will make altitude calculations that may affect the accuracy of the forecast. Once the 14 day learning mode process is complete, the learning mode icon will disappear and the weather forecast should be ready for superior operation.
